It is possible to compile ATLAS exactly for use on multi-cpu shared

but it should say in the documentation how to do it.
This should be a very easy way to use more CPUs. I think that simply
linking Octave to a pthreads enabled ATLAS library would be
sufficient. The interfaces should be the exact same as the single
processor library.
Cheers,
Peter.
Hello all, of the suggestions made, which all sound pretty reasonable,
I'm planning on trying this one. Before I do though, has anyone built
Octave using a parallel ATLAS? Does parallel ATLAS break operations
into a number of threads that depends on the size of the problem, or is
the same number of threads always used? Well, I hope to have some
results to report in a week or so. M.
