How to use 'CLBlastSgemmBatched'? #550

Open diverger opened 4 months ago

diverger commented 4 months ago

Hi,

I'm moving from ‘cublasCgemmBatched()’ to ‘CLBlastSgemmBatched()’, for the former, the A, B and C matrix is passed as array of pointer to array. Then how the matrix should be passed to the later? How should I pass the batched A1, A2, A3..., or B1, B2, B3, ..., etc to it? Use staked matrix?

Thanks.

Have you looked at the API docs or the sample usage of this function? The answer to your question is in the docs:

const cl_mem a_buffer: OpenCL buffer to store the input A matrix. const size_t *a_offsets: The offsets in elements from the start of the input A matrix. const size_t a_ld: Leading dimension of the input A matrix. This value must be greater than 0.
