Hello Beowulf,
My BSD is developing nicely. Last night it flopped into third place of the
late 1990's! The package is:
flops-2.1                      Floating point benchmark to give your MFLOPS
Simply type "flops."
Tonight I unpacked xhpl from hpl-2.3.tar.gz. If you are looking for it you
can find it here:
Building it was not a problem, it install a binary in /usr/local/bin, mpich
makes a handshake...then I see Illegal instruction (signal 4). This
probably means a problem with your application. etc... Refer to the FAQ...
Is this an MPI error or a Linpack error or something else?
I made a couple searches yielding very few results. It is known to exist.
It can be quieted though it might to not allow the application to run.
Should the input file run after being downloaded?
