	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 the thread "Where is everyone?" and found it to be expired.

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). -- Steve http://troutmask.apl.washington.edu/~kargl/
