--- Comment #9 from Dave Love <d.love@xxxxxxxxxxxxxxx> ---
I was going to comment on this.  I can't give a formal review, and I'm
about to go on holiday, but there's an amended spec at
https://loveshack.fedorapeople.org/review/hpl.spec
in case it's useful.  It builds on at least epel-6-x86_64 and fedora-20-x86_64
and passes rpmlint.

Obviously a serial version makes no sense as it's a distributed benchmark.

If you use the packaged atlas rather than openblas on x86_64 -- at least
on sandybridge -- the results are a factor of 3-ish(?) pessimistic.  I can't
remember the actual figure.  Openblas/openmpi give you essentially the same
results as the Intel proprietary stuff -- hooray for free software.

A devel package doesn't make sense for the benchmark, surely.

[Fedora badly needs the Debian model for BLAS to avoid this sort of issue.]
