TRSM used to have some issues - as much as I know.
I am not sure if this has been resolved now.
Will ask the BLAS team to look into this thread.
Can you provide some details? what library version? what OS? what GPU? what Catalyst version?
What is the size of your A matrix?
If you still think something is wrong, it would help if you can attach a sample code to help us reproduce the issue.
it seems I misread sth. in clAmdBlas.h.
With this error-meaning I figured out, that I forgot to check clCreateBuffer() which has an error 'CL_INVALID_BUFFER_SIZE' when my Right-Hand-side gets too big.
Thanks for your help.
