LAPACK/ScaLAPACK Development

I have PC with dual-core processor.I want to test parallel efficiency with it. could anyone give me an example code written by fortran for solving linear system of equations,wich can be run in dual-core processor PC?
Thanks a lot for your attention. :)

I am not sure what kind of example code you are looking for. LAPACK does not support SMP. There are some multi-threaded BLAS. However, LAPACK + (multi-threaded BLAS) show no speedup if multiple processors or cores present, even getting worse. If you like to test your dual core computer, there are some parallel programs on www.equation.com (select Parallel Computing, and then LAIPE). You can download and try it.

Cheers. :)
