OEOmegaSystemHasGPU

bool OEOmegaSystemHasGPU()

Determines whether a GPU is present on the current system. This will check that the system is a Linux platform and the /dev/nvidiaN file exits, where N can be between 0 and 100. It will not try to create a context on the GPU, so there is still the possibility that the GPU will not be available, either due to the driver being uninstalled or the GPU being used by another system user.
