Description
Hi,
We want to implement strided GEMM implementation where the dot product for each output element is computed using only even indexed elements from rows/columns of matrix A/B. Seems like the routine for GEMM is written in assembly? Is there a way to implement this without hacking the assembly? If assembly is the only way can you please help us with this?
Thanks,
Nitish

First steps
- Read the whole issue, then the project's contributing guide.
- Comment on the issue to say you are picking it up — it saves two people doing the same work.
- Fork the repository and make your change on a branch.
- Open a pull request that references the issue number.
Research direction
Start by locating the GEMM entry points and assembly routines in OpenBLAS, since the issue does not name a file or test. Determine whether strided access using only even-indexed elements of A and B can be supported without changing assembly. Done means the requested computation is implemented with documented behavior and coverage for the strided case.
