This chapter contains
performance results for
some ScaLAPACK drivers
on a range of different
platforms.
We recommend
that users compare their performance
results against the ones presented in the previous tables.
For those users whose computer is not listed,
the BLAS timing program [3] and
the message-passing benchmark program [46]
can be used to estimate
the values of 
, 
and 
for a specific computer.
The execution time can
then be estimated by
using the material
presented in the
previous section.
If this chapter does not contain performance data for the ScaLAPACK routine a user is using, we recommend verifying the performance with one of the drivers whose performance is presented in this chapter. The publicly available ScaLAPACK distribution contains timing programs for each driver. This performance sanity check should convince the user not only that the library has been correctly installed, but also that it is being used properly. Users may also send questions, suggestions, or comments regarding ScaLAPACK performance issues to scalapack@cs.utk.edu.
