Does brgemm support transA/transB?

[gengoks]

I notice that there is an option transA/transB in brgemm desc init.

status_t brgemm_desc_init(brgemm_t *brg, cpu_isa_t isa,
        brgemm_batch_kind_t type, impl::data_type_t dt_a,
        impl::data_type_t dt_b, bool transA, bool transB,
        brgemm_layout_t layout, float alpha, float beta, dim_t LDA, dim_t LDB,
        dim_t LDC, dim_t M, dim_t N, dim_t K, const brgemm_strides_t *strides)

But in its implementation, it will directly return unimplemented.

if (transA || transB) return status::unimplemented;

I would like to ask whether brgemm support transA and transB input. If not, do you have a plan to support such feature?

Hi @gengoks , thanks for your interest in brgemm! As you noticed, there is currently no support for transposed input in brgemm. We would like to add support at some point, but right now there is no definite plan for this feature.
