Allocating a CudaPitchedDeviceVariable using a width and height throws an ErrorInvalidValue exception.

[dennisai]

Hello,

When I try to execute the following code, I get an ErrorInvalidValue exception.

CudaContext cudaContext = new CudaContext(CudaContext.GetMaxGflopsDeviceId());
CudaPitchedDeviceVariable<ushort> var = new CudaPitchedDeviceVariable<ushort>(
    2048, 160);

I have tried with multiple parameters, such as (16, 16) for my width and height. It appears to work with float but not with ushort. Any idea why it doesn't support ushort?

Please see the CUDA DriverAPI documentation: http://docs.nvidia.com/cuda/cuda-driver-api/group__CUDA__MEM.html#group__CUDA__MEM_1gcbe9b033f6c4de80f63cc6e58ed9a45a

ElementSizeBytes may be 4, 8 or 16 (since coalesced memory transactions are not possible on other data sizes).

ushort size is 2 bytes

Great thank you RoBik75!
