Sun's clustering product is based on OpenMP and I've installed it on some
Solaris systems for my users to experiment with.  Sun also has the package
for Redhat and maybe SLED.  Sun is tracking OpenMP closely.

I'm a sysadmin and not a programmer FWIW.  It seems the HPC community is
standardizing OpenMP and that's probably a good thing.  Sun is probably
going to release its code if it hasn't already.
