BLAS and LAPACK from Netlib are the de facto libraries for linear algebra. If you would like to take advantage of the highly optimized matrix routines of LAPACK, OpenBLAS, or MKL, you can optionally compile the libwalrus such that Eigen uses these frameworks as backends. openblas-lapack-ilp64. Benefit to Fedora Using a single default BLAS implementation will avoid bugs stemming from having two different BLAS libraries loaded at runtime that causes computation errors. dsyrk(A,B): standard Lapack function to update B := alpha*A*A’ + beta*B, and here we need B: = -AA’+B. So I guess the 1/ solution is the good one : netlib LAPACK will be used both as an ABI and as the reference implementation ; each optimized version might provide its own set of specialized implementation preserving the ABI by linking against LAPACK-static. example for details. If just the matrix-matrix multiply is slow, it’s likely because core/_dotblas.
