Hi Oliver,
I know it's been a while, but I just wanted to update you on this report.
All of the problems are now fixed. I don't think there is any problem
with the cfd example. The code is written to execute 999 iterations,
so I think you just needed to let it run a little longer. I made the changes
you noted in the benchmark codes. I fixed the linking problems by
adding the proper Fortran libraries to the SGI configuration. I corrected
the problems in the Fortran portion of the qcd benchmark that were
causing it to crash. And I added a workaround for the SGI problem with
reductions on array expressions.
Regards, Julian C.
