The HPL package provides a testing and timing program to quantify
the accuracy of the obtained solution as well as
the time it took to compute it. The best performance achievable by this software on your system depends on a large variety
of factors. Nonetheless, with some restrictive assumptions on the
interconnection network, the algorithm described here and its
attached implementation are scalable in the sense
that their parallel efficiency is maintained constant with respect
to the per processor memory usage.
