[Bioclusters] High Availability Clustering

[Ron Chen]

Thanks!

Even I don't use PBSPro, I am happy that Altair is
still improving it. I am sure lots of PBS sites will
be excited about this feature.

Also, it would be great that you guys can backport
some of the fixes/enchancements to OpenPBS, while
adding new features like that into PBSPro.
