OpenCL SDK on VMWare

OpenCL SDK on VMWare

I have installed OpenCL SDK on VMWare and can run the example "Capsbasic" but if I try to run "MonteCarlo" or "GEMM" they fail with CL_DEVICE_NOT_AVAILABLE. Here is the otuput of all three:

Hello Bradley S.,

Thank you for sharing your issue.

In general VM doesn't report SSE4.2/SSE4.1 instrunction set required by the OpenCL driver.

Could you please check if it's the case with your VM.

a cat /proc/cpuinfo yields these flags:

Operating system virtualization is a convenient way to run multiple operating systems at the same time, on the same hardware, without requiring rebooting. There are several technologies that allow sharing of the GPU by both the host (native) and guest (virtualized) operating systems.

In case you're still interested in the topic of virtualization, there is an emerging pathway for access to the GPU in a virtual machine described here:

Please watch for more on this topic on this forum as well as Media SDK's.
