Embodiments of the present disclosure relate generally to the technical field of computing, and more particularly to computing with multiple processor tiles.
The background description provided herein is for the purpose of generally presenting the context of the disclosure. Unless otherwise indicated herein, the materials described in this section are not prior art to the claims in this application and are not admitted to be prior art by inclusion in this section.
A multi-tile processor may include multiple processor tiles. A processor tile may include a computing unit, a processor core, a core, a processing engine, an execution unit, or a central processing unit (CPU), caches, and switches. Each processor tile may be coupled to one or more neighboring processor tiles by interconnects according to a topology. A signal pathway from a first processor tile to a second processor tile may include one or more interconnects to couple the first processor tile to the second processor tile through some intermediate processor tiles.
A large number of processor tiles may be formed on a die. The large number of processor tiles on a die may increase the communication complexity as well as the defect rate of the processor tiles and interconnects. In current practice, in order for a multi-tile processor on a die to function properly, the multi-tile processor may have to have a near faultless hardware realization of the processor tiles and interconnects. Hence, a multi-tile processor with large numbers of tiles may not survive a practical manufacturing defect rate.
Embodiments will be readily understood by the following detailed description in conjunction with the accompanying drawings. To facilitate this description, like reference numerals designate like structural elements. Embodiments are illustrated by way of example and not by way of limitation in the figures of the accompanying drawings.
Apparatuses, methods, and storage medium are disclosed herein related to the formations of signal pathways including multiple processor tiles coupled by interconnects on a multi-tile processor with a defect rate. Current solutions for the formation of a signal pathway may employ techniques running on a single centralized controller. As such, current solutions for the formations of signal pathways between processor tiles of a multi-tile processor may not work when the multi-tile processor have a significant failure rate, e.g., larger than 4%, of the processor tiles or interconnects. Hereinafter, a processor tile may simply be referred to as a tile.
Embodiments herein may present techniques for automatic formation of a signal pathway between two processor tiles on a multi-tile processor with multiple processor tiles and interconnects, where a significant subset may be faulty. In embodiments, the formation of a signal pathway, which may be referred to as routing, may be based on decentralized local interactions between adjacent tiles, to produce a dedicated signal pathway that may be optimal against selectable criteria, such as latency, energy, heat, or routing density of adjacent tiles. Without a centralized controller for the formation of a signal pathway, unsupervised local message passing between random collections of tiles on the multi-tile processor may be utilized to form the signal pathway. The formation of a signal pathway between any two processor tiles may be modeled on the dynamics of material self-assembly, following governing equations for a physical system having multiple elements. Such a decentralized or distributed solution for the formation of signal pathways may overcome fundamental limits on scaling, complexity, adaptation and setup time, for a multi-tile processor with multiple processor tiles and interconnects, where a significant subset may be faulty. Embodiments herein may be applicable to a multi-tile processor for tile counts larger than 500, e.g., in the range of about 500 to O(104), with defect rates in the range of 5-20%. Additionally, embodiments herein may have performances that scales with the number of tiles, e.g., scaling over 10,000 tiles, such as 70,000 tiles.
Embodiments herein may present a multi-tile processor including a plurality of processor tiles, and a plurality of interconnects selectively coupling the plurality of processor tiles to each other. At least a first processor tile of the plurality of processor tiles may include a memory to store a bulletin board to hold a message, an execution unit coupled to the memory, and an encapsulated software module to be executed by the execution unit. The encapsulated software module, in response to execution, may select a second processor tile of the plurality of processor tiles coupled with the first processor tile by an interconnect to be a part of a signal pathway. The second processor tile may be selected based at least in part on a selection criterion of the signal pathway and the message held in the bulletin board. The encapsulated software module may post and read a message at the bulletin board stored in the memory, or read a message from a bulletin board stored in a memory of the second processor tile.
Embodiments herein may present a multi-tile processor including a plurality of processor tiles, and a plurality of interconnects selectively coupling the plurality of processor tiles to each other. One or more of the plurality of processor tiles, or one or more of the plurality of interconnects may be faulty. A signal pathway may exist between a first processor tile and a second processor tile of the plurality of processor tiles. The signal pathway may include a set of non-faulty processor tiles and a set of non-faulty interconnects selected from the plurality of processor tiles and the plurality of interconnects. Each intermediate processor tile of the signal pathway, between the first and the second processor file, may select an adjacent non-faulty processor tile and a non-faulty interconnect coupling the selecting processor tile to the adjacent non-faulty processor tile to constitute the signal pathway.
Embodiments herein may present a method for configuring a signal pathway on an integrated circuit (IC) die. The method may include: selecting, by a first processor file, an adjacent processor tile of the first processor tile to be a part of the signal pathway to a second processor tile, the adjacent, first and second processor tiles being members of the IC die. The method may further include: receiving subsequently, from the adjacent processor tile, by the first processor tile, a confirmation that all intermediate processor tiles of the signal pathway to the second processor tile have been selected. In addition, the method may include: configuring, by the first processor tile, in response to the receipt of the confirmation, internal circuitry of the first processor tile, to enable the first processor tile to participate in signal routing on the signal pathway.

Among them, the processor tile 107, the processor tile 109, the processor tile 111, the processor tile 113, or the processor tile 105, may be an intermediate processor tile. The processor tile 101 may select the processor tile 107 among a set of adjacent processor tiles to be a part of the signal pathway 110, based at least in part on a selection criterion of the signal pathway 110.

Furthermore, the processor tile 109 may select the processor tile 111 from a set of adjacent processor tiles to be a part of the signal pathway 110.
In embodiments, the signal pathway 110 between the processor tile 101 and the processor tile 103 may be a shortest path between the processor tile 101 and the processor tile 103 based on the selection criterion applied to the plurality of processor tiles. The selection criterion may include a relationship between a processor tile and other processor tiles of the computational device 100, defined by a congestion, a distance, a load balance, a heat energy, or a boundary limit.
In embodiments, the physical system 210 may include multiple mass elements, e.g., a mass element 201, a mass element 203, a mass element 205, a mass element 207, a mass element 208, and a mass element 209, coupled by springs, e.g., a spring 211, a spring 213, a spring 215, a spring 217, a spring 219, a spring 216, and a spring 218, according to a topology as shown. The springs, e.g., the spring 211, the spring 213, the spring 215, the spring 217, the spring 219, the spring 216, and the spring 218, may have a uniform spring constant. In addition, the mass elements, e.g., the mass element 201, the mass element 203, the mass element 205, the mass element 207, the mass element 208, and the mass element 209 may have a uniform mass value. According to the law of physics, e.g., Hooke's law of force related to spring constant and distances, the physical system 210 may converge to a uniform spatial distribution of the mass elements. Starting from a random initial position, the mass elements may undergo damped harmonic oscillation, going through parameters and the range of values over which the transient response may converge, and ultimately converging to a stable rest state, as shown in
In embodiments, the computational device 220 may include processor tiles, e.g., a processor tile 221, a processor tile 223, a processor tile 225, a processor tile 227, a processor tile 228, and a processor tile 229, coupled by signal pathways, e.g., a signal pathway 231, a signal pathway 233, a signal pathway 235, a signal pathway 237, a signal pathway 239, a signal pathway 236, and a signal pathway 238, according to a topology as shown. The topology for the multiple signal pathways, e.g., the signal pathway 231, the signal pathway 233, the signal pathway 235, the signal pathway 237, the signal pathway 239, the signal pathway 236, and the signal pathway 238 may be formed according to an equivalence between a complex physical system, e.g., the physical system 210, and a target virtual structure of multiple signal pathways, and may be similar to the topology for the springs, e.g., the spring 211, the spring 213, the spring 215, the spring 217, the spring 219, the spring 216, and the spring 218.
In embodiments, the topology of the multiple signal pathways in the computational device 220 may be formed based on the equivalence of the physical system 201 to import the analytic tools and governing equations from the physical system 210, e.g., Hooke's law of force, and further use the governing equations to exert robust engineering control over the formation of the large scale virtual structures of multiple signal pathways. In other words, a mature set of analytic tools for a physical system, e.g., the physical system 210, may be applied to engineer robust on-die network structures of multiple signal pathways for the computational device 220.
In embodiments, the topology of the multiple signal pathways in the computational device 220 may be formed by self-assembly based on local unsupervised interactions of processor tiles. Physical chemists may define material self-assembly as “the spontaneous organization of objects, under equilibrium conditions, into stable aggregates.” Local unsupervised interactions between independent agents of a self-assembly system may give rise to complex global structures with extreme scale invariance and tolerance to component failure. Mapping of a self-assembly physical system, e.g., the physical system 210, based on local unsupervised interactions to a computational device, e.g., the computational device 220, may preserve the properties of scale invariance and defect tolerance, to generate robust, complex topologies for the computational device. When a physical system, e.g., the physical system 210, is mapped to a computational device, e.g., the computational device 220, the multiple elements of the physical system may correspond to multiple processor tiles of the computational device. Details of operations by a processor tile may be shown in

Multiple encapsulated software modules, e.g., an encapsulated software module 321, or a virtual encapsulated software module 323, may be executed by the execution unit 303. The virtual encapsulated software module 323 may interleave execution of the multiple encapsulated software modules, e.g., the encapsulated software module 301 and the encapsulated software module 321, by time-shared processing on the execution unit 303. The memory 305 may store the bulletin board 351 to hold a message 352, a tokenized message 354, the numeric field 361, the numeric field 363, and the numeric field 365. The encapsulated software module 301 may post and read a message, e.g., the message 352, at the bulletin board 351 stored in the memory 305. The memory 305 may further include tag data 353, which may identify the processor tile 300.
In embodiments, a rule of the set of rules 313 may specify a response to one or more messages held in the bulletin board 351, or a message to a bulletin board of an adjacent processor tile. For example, the response may include information for a replication operation, information for a self-deletion operation, information for an operation to post a local message, information for an idling operation, information for an operation to update a hop count of the signal pathway, information for a propagation operation, information for a numerical calculation, or information for an operation to estimate a distance.
In embodiments, the payload 315 may include data or code to be delivered to an adjacent processor tile. The data or the code included in the payload 315 may be generated by the encapsulated software module 301 based on an atomic function, and wherein the atomic function includes a parameter, an equation, or a single operation. The encapsulated software module 301 may post the message 352 with the payload 315.
In embodiments, the state vector 317 may represent the status of the encapsulated software module 301. The encapsulated software module 301 may encode the state vector 317 into the tokenized message 354 to represent the encapsulated software module 301, and may further post the tokenized message 354 in the bulletin board 351. An adjacent processor tile may read the tokenized message 354, and may instantiate the encapsulated software module 301 by processing the tokenized message. In this way, the encapsulated software module 301 may be cloned into the adjacent processor tile by message passing the tokenized message 354.
In embodiments, the numeric field 361 may include a set of key-value pair posted in the bulletin board 351. The numeric field 361 may be generated or managed by the encapsulated software module 301. The value of the numeric field 361 may be equivalent to a value of a continuous two-dimensional function discretely sampled at the spatial coordinates of the processor tile 300. In addition, the encapsulated software module 301 may compute the numeric field 363 based on the numeric field 361, and other numeric fields of adjacent processor tiles. Furthermore, the numeric field 365 may be a hierarchical numeric field that includes a first level numeric field, e.g., the numeric field 361, and a second level numeric field, e.g., the numeric field 363, and the second level numeric field is computed by the encapsulated software module 301 based on the first level numeric field. The numeric fields may be resilient to processor tile failures and readily scalable to a computational device with a large number of processor tiles, e.g., larger than 10,000 processor tiles.
In embodiments, the processor tile 300 may be mapped to an element of a physical system, e.g., the physical system 210, to perform self-assembly functions to form a signal pathway according to governing equations for the physical system. The dynamics of the self-assembly functions may be captured by the encapsulated software module 301, the bulletin board 351, and numeric fields. These dynamics of self-assembly may be used to guide the encapsulated software module 301 to form the signal pathway. According to the mapping, the encapsulated software module 301 may begin from a random initial position, limit the communication to message passing between adjacent processor tiles, and still anneal to a final configuration that is globally optimal. For example, the processor tile 300 may be a processor tile of a computational device mapped to matched pairs of chemical ions combining, with the following correspondences.
In embodiments, the processor tile 410 may include a memory 405, an execution unit 403 coupled to the memory 405, and an encapsulated software module 401 to be executed by the execution unit 403. The encapsulated software module 401 may include an API 411, where the API 411 may include commands 412 to communicate with the execution unit 403 or to communicate with other processor tiles, e.g., the processor tile 420. The encapsulated software module 401 may further include a set of rules 413, a payload 415, and a state vector 417. Multiple encapsulated software modules, e.g., an encapsulated software module 421, or a virtual encapsulated software module 423, may be executed by the execution unit 403. The memory 405 may store the bulletin board 451 to hold a message 452, a tokenized message 454, a numeric field 461, and a numeric field 463. More messages or more numeric fields may be stored in the bulletin board 451.

The encapsulated software module 402 may further include a set of rules 424, a payload 426, and a state vector 428. Multiple encapsulated software modules, e.g., an encapsulated software module 441, may be executed by the execution unit 404. The memory 406 may store a bulletin board 472 to hold a message 482, a tokenized message 484, a numeric field 491, and a numeric field 493. More messages or more numeric fields may be stored in the bulletin board 472. The encapsulated software module 402 may post and read a message, e.g., the message 482, at the bulletin board 472 stored in the memory 406. In addition, the encapsulated software module 402 may read the bulletin board 451 of the processor tile 410, and the encapsulated software module 401 may read the bulletin board 472 of the processor tile 420, so that messages may be passed between the processor tile 410 and the processor tile 420.
In embodiments, the encapsulated software module 401 may perform functions of self-assembly by message passing through bulletin boards, e.g., the bulletin board 451 and the bulletin board 472 of the adjacent processor tile 420. In detail, the encapsulated software module 401, in response to execution by the execution unit 403, may select the processor tile 420 from one or more adjacent processor tiles of the processor tile 410, to be a part of a signal pathway, based at least in part on a selection criterion of the signal pathway. The encapsulated software module 401 may make the selection based on the message 452 held in the bulletin board 451, or the message 482 held in the bulletin board 472, while applying a selection criterion for the signal pathway. The selection criterion for the signal pathway may be based on a relationship between the processor tile 410 and other adjacent processor tiles, e.g., the processor tile 420, defined by a congestion, a distance, a load balance, a heat energy, or a boundary limit.
In embodiments, the encapsulated software module 401 in the processor tile 410 may be different or perform functions different from the encapsulated software module 402 in the processor tile 420. The encapsulated software module 401 may determine or detect that the processor tile 420 to be an unoccupied processor tile, when the processor tile 420 does not have a copy of the encapsulated software module 401. On detection of the unoccupied processor file, the encapsulated software module 401 may clone a copy of itself to be placed into the processor tile 420 to make the processor tile 420 an occupied processor tile. The cloning of the encapsulated software module 401 may be accomplished by generating a tokenized message of the encapsulated software module 401, e.g., the tokenized message 454, placing the tokenized message in the bulletin board 451, where the processor tile 420 may read the bulletin board 451 for the tokenized message 454. The processor tile 420 may further make a copy of the tokenized message 454 to become the tokenized message 484 stored in the bulletin board 472, and further instantiate the encapsulated software module 401 to become the encapsulated software module 441, by processing the tokenized message 484 on the processor tile 420.
In embodiments, the encapsulated software module 441, which may be a cloned copy of the encapsulated software module 401 in the occupied processor tile, e.g., the processor tile 420, may generate the numeric field 493 on the processor 420, and the numeric field 493 may be updated from the numeric field 461 of the processor tile 410.

The encapsulated software module, e.g., the encapsulated software module 505, the encapsulated software module 515, the encapsulated software module 525, the encapsulated software module 535, the encapsulated software module 545, may perform spatial optimizations on these numeric fields to guide their migration and sequencing of the signal pathway 500. The encapsulated software modules may manage the formation of the signal pathway 500 via locally visible message posts in the bulletin boards, e.g., the bulletin board 504, the bulletin board 514, the bulletin board 524, the bulletin board 534, or the bulletin board 544.
In embodiments, the signal pathway 610 may include the processor tile 601 and the processor tile 641, with intermediate processor tiles, e.g., the processor tile 611, the processor tile 621, and the processor tile 631. The processor tile 601 may include a memory 602, and an execution unit 603 coupled to the memory 602. The memory 602 may store a bulletin board 604 to store messages or numeric fields. The processor tile 611 may include a memory 612, and an execution unit 613 coupled to the memory 612. The memory 612 may store a bulletin board 614 to store messages or numeric fields. The processor tile 621 may include a memory 622, and an execution unit 623 coupled to the memory 622. The memory 622 may store a bulletin board 624 to store messages or numeric fields. The processor tile 631 may include a memory 632, and an execution unit 633 coupled to the memory 632. The memory 632 may store a bulletin board 634 to store messages or numeric fields. The processor tile 641 may include a memory 642, and an execution unit 643 coupled to the memory 642. The memory 642 may store a bulletin board 644 to store messages or numeric fields.
As shown in
Based on the set of rules 617, the encapsulated software module 615 may post the numerical field 616 to the bulletin board 614, where the numerical field 616 may have a key-value pair as HC=0. In addition, the encapsulated software module 615 may scan all adjacent processor tiles to find any adjacent processor tiles that do not have a copy of the encapsulated software module 615. The encapsulated software module 615 may scan all adjacent processor tiles by checking the bulletin boards of the adjacent processor tiles. For example, the encapsulated software module 615 may detect that the processor tile 601 does not contain a copy of the encapsulated software module 615. After detecting the processor tile 601 does not contain a copy of the encapsulated software module 615, the encapsulated software module 615 may clone a copy of itself and uses its API to queue the copied encapsulated software module 615 for transfer to the unpopulated adjacent processor tile 601.

Similarly, the encapsulated software module 635 may scan all adjacent processor tiles by checking the bulletin boards of the adjacent processor tiles, and may detect that the processor tile 641 does not contain a copy of the encapsulated software module 635. Afterwards, the encapsulated software module 635 may clone a copy of itself and uses its API to queue the copied encapsulated software module 635 for transfer to the unpopulated adjacent processor tile 641. The cloned copy of the encapsulated software module 635 may enter the processor tile 641, to be an encapsulated software module 645 with a set of rules 647. The encapsulated software module 645 may compute its own hop count as an increment of the smallest visible hop count, and format the updated hop count in a numeric field 646 with a value as 3, incremented by 1 from the value of the numeric field 636.
In addition, according to the rule of estimating distance (D), the encapsulated software module 625 may computes a second numeric field 628 with a real-valued distance, computed by averaging all the integer hop counts that it can detect. Since the processor tile 611 and the processor tile 631 may be the processor tiles the encapsulated software module 625 may detect, the integer hop count of the processor tile 611 is 0, and the integer hop count of the processor tile 631 is 2, the encapsulated software module 625 may compute a numeric field 628 as D=1. Similarly, the encapsulated software module 635 may calculate a numeric field 638 as D=2, which is an average of the HC=1 for the processor tile 621, and the HC=3 for the processor tile 641. Furthermore, the encapsulated software module 645 may calculate a numeric field 648 as D=2.5, which is an average of the HC=2 for the processor tile 631 and HC=3 for the processor tile 641. The encapsulated software module 615 may calculate a numeric field 618 D=0.66, which is an average of the HC=1 for the processor tile 621, HC=1 for the processor tile 601, and HC=0 for the processor tile 611.

With increasing levels of the hierarchy, the function curves of the numeric fields may become piecewise differentiable, which may enable use of powerful distributed optimization functions whose convergence may depend on spatial continuity.
In embodiments, the signal pathway 1110 may include the processor tile 1101 and the processor tile 1141, with intermediate processor tiles, e.g., the processor tile 1111, the processor tile 1121, and the processor tile 1131.

The processor tile 1141 may include a memory 1142, and an execution unit 1143 coupled to the memory 1142. The memory 1142 may store a bulletin board 1144 to store messages or numeric fields.
In embodiments, the processor tile 1101 may further include an encapsulated software module 1105 that generates a numeric field 1106, an encapsulated software module 1107 that generates a numeric field 1108. In embodiments, there may be relationships between the numeric field 1106 and the numeric field 1108. For example, the numeric field 1108 may be calculated based on a formula 1/(1+x), where the variable x may be the value of the numeric field 1106. The numeric field 1106 and the numeric field 1108 may form a hierarchal numeric field.
In addition, the processor tile 1101 may include a virtual encapsulated software module 1109 to manage the executions of the encapsulated software module 1105 and the encapsulated software module 1107. For example, the virtual encapsulated software module 1109 may interleave execution of the encapsulated software module 1105 and the encapsulated software module 1107 by time-shared processing on the execution unit 1103.
The encapsulated software module 1105, the encapsulated software module 1107, and the virtual encapsulated software module 1109 may be cloned from the processor tile 1101 into the processor tile 1111, the processor tile 1121, the processor tile 1131, and the processor tile 1141, respectively. Multiple numeric fields and a hierarchal numeric field may be generated accordingly. The details of the cloning of the encapsulated software modules and the numeric fields in other processor tiles are not shown.
In embodiments, as shown in
In embodiments, per their internalized set of rules, each of the encapsulated software module 1221, the encapsulated software module 1222, the encapsulated software module 1223, the encapsulated software module 1224, may model the ‘energy field strength’ of a processor tile as a sum of the numeric field values from the other encapsulated software modules. At run time, each of the encapsulated software modules may post a message on its bulletin board that initiates a gradient radiating outward from its current location. At each local, e.g., unsynchronized time step, each of the encapsulated software modules may compute the energy field strength at its host processor tile and the energy of the one or two neighboring processor tiles. In addition to the energy field strength, the encapsulated software module may carry tag data that can identify the source of the encapsulated software module. As processing proceeds, the encapsulated software modules may use messages posted on the locally visible bulletin board to compute the cumulative energy field strength at their current processor tiles and at the immediately neighboring processor tiles. Migrating in a minimum energy direction may result in a uniform spatial distribution, regardless of initial position for the encapsulated software module.

The process 1400 may start at an interaction 1401. During the interaction 1401, a first processor tile may select an adjacent processor tile of the first processor tile to be a part of a signal pathway to a second processor tile, where the first processor tile, the adjacent processor tile, and the second processor tiles are members of an IC die. For example, at the interaction 1401, the processor tile 101 may select the processor tile 107 adjacent to the processor tile 101 to be a part of the signal pathway 110 to the processor tile 103. The processor tile 101 may be similar to the processor tile 300 and may include an encapsulated software module. The processor tile 107 adjacent to the processor tile 101 may be selected by the encapsulated software module, based on a selection criterion for the signal pathway 110.
During an interaction 1403, the first processor tile may receive subsequently, from the adjacent processor tile, a confirmation that all intermediate processor tiles of the signal pathway to the second processor tile has been selected. For example, at the interaction 1403, the processor tile 101 may receive subsequently, from the processor tile 107 processor tile 101, a confirmation that all intermediate processor tiles of the signal pathway 110 to the processor tile 103 has been selected.
During an interaction 1405, the first processor tile may configure, in response to the receipt of the confirmation, internal circuitry of the first processor tile, to enable the first processor tile to participate in signal routing on the signal pathway. For example, at the interaction 1405, the processor tile 101 may configure, in response to the receipt of the confirmation, internal circuitry of the processor tile 101, to enable the processor tile 101 to participate in signal routing on the signal pathway 110.
