Abstract

The embodiments relate to a computer system, and management of an operating mode of a general-purpose computing on graphics processing unit (GPGPU) adapter. A tool is provided to control the function of the GPGPU adapter. The tool includes an input/output (I/O) interface operatively coupled to the GPGPU adapter. The tool further includes basic input/output system (BIOS) to determine presence of the GPGPU adapter and to interrogate the GPGPU adapter to automatically set an operating mode of the GPGPU adapter. At least two modes of the GPGPU adapter are provided. The GPGPU adapter is set to a first mode in response to determining that the GPGPU adapter is in communication with the visual display, and set to the second mode in response to determining that the GPGPU is not in communication with a visual display.

First claim

What is claimed is:

1. A system comprising:
a computer system comprising a processing unit operatively coupled to memory, a video device for outputting video data, and a basic input/output system (BIOS);
a general-purpose computing on graphics processing unit (GPGPU) adapter;
a visual display; and
a tool in communication with the processing unit to control the function of the GPGPU adapter, the tool comprising:
an input/output (I/O) interface operatively coupled to the processing unit, wherein the GPGPU adapter and the visual display are in communication with the I/O interface, wherein the GPGPU adapter is in communication with the I/O interface via a communication bus; and
the BIOS to determine presence of the GPGPU adapter;
the BIOS to interrogate the GPGPU adapter based on the determined presence, including determining communication between the visual display and the GPGPU adapter;
the BIOS to automatically set an operating mode of the GPGPU adapter based on the determined communication wherein the GPGPU adapter is set to the first mode in response to determining that the GPGPU adapter is in communication with the visual display and automatically set to the second mode if the GPGPU adapter is not in communication with the visual display; and
wherein the first mode of the GPGPU adapter is a graphics mode to operate at a first resolution, and the second mode of the GPGPU adapter is a computational mode to operate at a second resolution wherein the first resolution is directed at video data and the second resolution is directed at computational data, wherein the first resolution is different than the second resolution.

2. The system of claim 1 , further comprising the BIOS to automatically re-initialize the GPGPU adapter to operate in the first mode following reading of extended display identification data (EDID) information provided to the BIOS by the visual display via the GPGPU adapter.

3. The system of claim 2 , further comprising the GPGPU adapter to output video at the first resolution from the GPGPU adapter, and the BIOS to disable the video device.

4. The system of claim 3 , wherein the video device is a video application-specific integrated circuit (ASIC).

5. The system of claim 1 , further comprising the BIOS setting the GPGPU adapter to the second mode in response to determining that the GPGPU adapter is not in communication with the visual display.

6. The system of claim 5 , further comprising, in response to the GPGPU adapter being set to the second mode, the video device to output video data and the GPGPU adapter performing computations.

7. The system of claim 5 , wherein setting the GPGPU adapter to the second mode includes the BIOS to automatically re-initialize the GPGPU adapter to operate in the second mode.

8. The system of claim 1 , wherein the communication bus is a PCIe bus.

9. The system of claim 1 , further comprising the BIOS to automatically set an operating mode of the GPGPU adapter during the initialization of an operating system.

10. The system of claim 2 , wherein the video device is in communication with the visual display.

11. A method comprising:
determining, by a basic input/output system (BIOS) operatively coupled to an operating system, presence of a general-purpose computing on graphics processing unit (GPGPU) adapter;
interrogating, by the BIOS, the GPGPU adapter, including determining communication between the GPGPU adapter and a visual display; and
automatically setting, by the BIOS, an operating mode of the GPGPU adapter based on the determined communication;
wherein the GPGPU adapter is set to the first mode in response to determining that the GPGPU adapter is in communication with the visual display and automatically set to the second mode if the GPGPU adapter is not in communication with the visual display: and
wherein the first mode of the GPGPU adapter is a graphics mode to operate at a first resolution, and the second mode of the GPGPU adapter is a computational mode to operate at a second resolution wherein the first resolution is directed at video data and the second resolution is directed at computational data, wherein the first resolution is different than the second resolution.

12. The method of claim 11 , further comprising the BIOS automatically re-initializing the GPGPU adapter to operate in the first mode following reading of extended display identification data (EDID) information provided by the visual display.

13. The method of claim 12 , further comprising outputting video at the first resolution from the GPGPU adapter, and the BIOS disabling a video device for outputting video data.

14. The method of claim 11 , wherein setting the GPGPU adapter to the second mode includes the BIOS automatically re-initializing the GPGPU adapter to operate in the second mode.

15. The method of claim 14 , further comprising outputting video associated with the video device, and using the GPGPU adapter to perform computations.

16. A computer program product for controlling a function of a general-purpose computing on graphics processing unit (GPGPU) adapter, the computer program product comprising a computer readable storage device having program code embodied therewith, the program code executable by a processing unit to:
determine, by a basic input/output system (BIOS) operatively coupled to an operating system, presence of a general-purpose computing on graphics processing unit (GPGPU) adapter;
Interrogate the GPGPU adapter, by the BIOS, including determine communication between the GPGPU adapter and a visual display;
sending by the BIOS, video data to the visual display, including:
automatically set by the BIOS, an operating mode of the GPGPU adapter based on the determined communication;
wherein the GPGPU adapter is set to the first mode in response to determining that the GPGPU adapter is in communication with the visual display, including the GPGPU adapter to send the video data to the visual display, and

wherein the GPGPU adapter is automatically set to the second mode in response to determining that the GPGPU adapter is not in communication with the visual display including a video device to send the video data to the visual display; and
wherein the first mode of the GPGPU adapter is a graphics mode to operate at a first resolution, and the second mode of the GPGPU adapter is a computational mode to operate at a second resolution wherein the first resolution is directed at video data and the second resolution is directed at computational data, wherein the first resolution is different than the second resolution.

17. The method of claim 16 , further comprising the BIOS automatically re-initializing the GPGPU adapter to operate in the first mode following reading of extended display identification data (EDID) information provided by the visual display.

18. The method of claim 17 , further comprising outputting video at the first resolution from the GPGPU adapter, and the BIOS disabling the video device for outputting video data.

19. The method of claim 16 , wherein setting the GPGPU adapter to the second mode includes the BIOS automatically re-initializing the GPGPU adapter to operate in the second mode.
