cuMemExportToShareableHandle always returns CUDA_ERROR_INVALID_VALUE #27

Closed vzhurba01 closed 1 year ago

vzhurba01 commented 2 years ago

The output variable cshareableHandle_ptr is incorrectly set to NULL and is passed to CUDA, thus always returning CUDA_ERROR_INVALID_VALUE.

The following similar APIs are likely not working either since they too have output variable void*:

cuMemExportToShareableHandle
cuDeviceGetNvSciSyncAttributes
cudaDeviceGetNvSciSyncAttributes
cuMemPoolExportToShareableHandle
cudaMemPoolExportToShareableHandle
cudaGraphMemFreeNodeGetParams
cuMemGetHandleForAddressRange

Resolved in v11.8.1
