First of all, this mail list is for Open MPI issues. On this list are
people who are helpful and know about lots of stuff (including things
having anything at all to do with MPI), but HPL and HPCC have their own
support mechanisms and you should probably pursue those for HPL questions.

Anyhow, if I google "blas", I immediately come up with, which
is where you can get a BLAS source tar file. I've had to go through the
HPL experience myself in the last 0-2 days, and it seems to me that the site is not responding. So, one can google "netlib mirror"
to find mirror sites, poke around a little, and end up getting BLAS from
the Sandia mirror site.

Short version: try

I found a gotcha. I changed the "g77" in the BLAS/ file to
become mpif77. Also, in the HPL hpl/Make.$ARCH file, I used mpif77 for
the linker. This way, some Fortran I/O routines used by blas (xerbla.f)
will be found at link time. (I was using HPL from HPCC. Not sure if
your HPL is the same.)
