1. Field of the Invention
Embodiments of the present invention generally relate to computer system architectures. More particularly, embodiments of the present invention relate to using a graphics system to enable a multi-user computer system.
2. Related Art
Technological advances have significantly improved the performance of the computer system. However, there is a limit to the improvement in performance solely from technological advances. In the past, the computer system was mostly a productivity tool. Now, the computer system is evolving into both a digital entertainment tool and a productivity tool.
The traditional architecture of the computer system envisions a single user. If the computer system is configured with greater processing power (e.g., by increasing the number of processors), greater storage capacity (e.g., by increasing the size of the hard drive), and greater network communication capacity (e.g., by increasing network communication bandwidth), the typical single user underutilizes the resources of the computer system. Thus, the typical single user is not willing to pay the additional premium associated with scaling the traditional architecture.
A graphics system and a multi-user computer system are disclosed. The graphics system comprises a graphics processing unit (GPU) for processing pixels. It further includes a multi-user manager for allocating pixel processing capability for each one of a plurality of users, wherein each user uses a display and an input device. Moreover, the graphics system has a plurality of user attributes for each user.
The multi-user computer system comprises a central processing unit (CPU) and a disk drive configured to support a plurality of users. Further, the multi-user computer system includes the graphics system.
The accompanying drawings, which are incorporated in and form a part of this specification, illustrate embodiments of the invention and, together with the description, serve to explain the principles of the present invention.
Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings. While the invention will be described in conjunction with the preferred embodiments, it will be understood that they are not intended to limit the invention to these embodiments. On the contrary, the invention is intended to cover alternatives, modifications and equivalents, which may be included within the spirit and scope of the invention as defined by the appended claims. Furthermore, in the following detailed description of the present invention, numerous specific details are set forth in order to provide a thorough understanding of the present invention.
As depicted in
Each user is connected via a wired or wireless network connection (e.g., network connection 1, network connection 2, network connection 3, and network connection 4) to the multi-user computer system 100. In practice, the users share the resources of the multi-user computer system 100. Moreover, the multi-user computer system 100 provides computational processing, storage, network communication, and graphical/pixel processing services to the users. For example, graphics-intensive processing applications may be executed at the multi-user computer system 100 and then displayed and interacted with on the PDA and the cell phone.
As shown in
The graphics system 60 includes a graphics processing unit (GPU) 62, a multi-user manager 64, and user attributes (e.g., user 1 attributes, user 2 attributes, user 3 attributes, and user 4 attributes) for each user. The user attributes include the display size of the display used by each user. The GPU 62 is a semiconductor device that specializes in rapidly processing graphical or pixel data compared to a typical central processing unit (CPU) 10. The GPU 62 may also be utilized for general purpose processing tasks typically performed by the CPU 10. The graphics system 60 may also have multiple GPUs 62. Further, additional GPUs 62 may be added to the graphics system 60 in any one of numerous ways. For example, a module (e.g., graphics card) having a single GPU or multiple GPUs may be coupled to the graphics system 60. Moreover, multiple modules (e.g., graphics cards) having a single GPU or multiple GPUs may be coupled to the graphics system 60. Further, the GPU 62 may have one or multiple cores for graphical data processing.
The multi-user manager 64 receives requests for the multi-user computer system 100 to support additional users. The multi-user manager 64 decides whether to accept the request. If the multi-user manager 64 accepts the request, the multi-user manager allocates pixel processing capability for the additional user and creates user attributes for the additional user.
Referring again to
At Block 310, the graphics system 60 of the multi-user computer system 100 is requested to support an additional user. In particular, the multi-user manager 64 receives the request to support the additional user. Moreover, the multi-user manager 64 decides whether to accept the request.
Continuing, at Block 320, pixel processing capability is allocated for the additional user if the graphics system 60 accepts the request. Allocation of pixel processing capability is depicted in
In an embodiment, the request may include proof of an additional license for the additional user to use the graphics system. In another embodiment, the request may include an authorization key obtained after payment of a fee. In yet another embodiment, the request may include payment for supporting the additional user.
Further, at Block 330, the multi-user computer system 100 is configured to support the additional user. This configuration includes creating a section for the additional user in the disk drive 50 of the multi-user computer system 100.
In sum, a seamless experience for multiple users is created at a reduced cost and without a cumbersome process.
The foregoing descriptions of specific embodiments of the present invention have been presented for purposes of illustration and description. They are not intended to be exhaustive or to limit the invention to the precise forms disclosed, and many modifications and variations are possible in light of the above teaching. The embodiments were chosen and described in order to best explain the principles of the invention and its practical application, to thereby enable others skilled in the art to best utilize the invention and various embodiments with various modifications as are suited to the particular use contemplated. It is intended that the scope of the invention be defined by the Claims appended hereto and their equivalents.
