gcc fortran matmul


In Gnu GCC, is the fortran compiler using ATLAS for matmul?

I didn't know sci.bio.paleontology was that low traffic until I tried read

If you specify -fexternal-blas, then it uses whatever BLAS you link it
to.

By default matmul does not use blas.  If you use -fexternal-blas
you can use whatever blas library you have (GotoBLAS, ACML, ATLAS,
good old netlib blas).
