LINPACK can take quite a while to tune for best performance.
mpi_mandel works, but i've never seen very consistant results from
it. (Maybe i dont hold my toes right.)
If you are looking for some quick, consistant numbers to show off to your
sponser, find an embarrassingly parallel application that has a
near-linear increase in speed with the number of processors.
One such application is MPI-Povray. Onother one is mpi-bladeenc.
