Nowadays, low end workstations or personal computers have
good performance for a small scale numerical problems.
But for larger problems, these machines may not have enough
memory nor performance.
In this paper I will present some numerical analysis performance
evaluations with workstation clusters(with up to 64 workstations)
For the sake of comparison with commercial parallel machines,
I adapted my method to some of the NPB(NAS Parallel Benchmarks)
such that CG, FT, MG.
