The last NCSA Linux cluster (Urbana-Champaign, IL) provides 512
dual PIII 1GHz, so a theoritical peak of 1 TFLOPS :

Very true (actually, it measures the upper bound on compute
performance of a dense linear algebra double precision
computation, which indeed covers a large set of // apps. There is
a lot of other codes that do not behave like LU, specially for the
ratio computation/communication).

I don't know MPLinpack. Don't you mean HPLinpack ?
