Description Christoph Hertzberg 2019-10-14 12:44:12 UTC
Related to Bug 1758 (and, it may actually not worth to use blocking algorithms for custom types, especially if sub-optimal cache access is less expensive than copying.

This not only applies to GEMM/GEMV products but also, e.g., triangular solvers.

Yes that's one of the many items I have had in my mind for years...
