@marcoabreu @szha Thank you for inputs! We are able to build natively as the ARM team suggested that its more performant this way instead of cross-compilation.
Eigen does install headers only but it also has `libeigen_blas.so` and `libeigen_lapack.so`. Unfortunately it doesn't provide all thr LAPACK APIs so Its not usedul for LAPACK: https://gitlab.com/libeigen/eigen/-/issues/2221#note_554042309 The file `libeigen_blas.so` does have APIs for `gemm`, `syrk`, `trsm` and `trmm`. But these are not CBLAS APIs but BLAS APIs so currently modifying these inside the code to evaluate the performance of its BLAS support only at Ops level and model level. -- You are receiving this because you were mentioned.
