[Bioclusters] openpbs / pbspro feature question

[Chris Dagdigian]

"why bother?" doesn't cut it for me :) as I need to explain to people 
who ask how to chose the best distributed resource management system 
(DRM) for their cluster or compute farm. They ask because I keep telling 
people that it is one of the most important decisions they make when 
sourcing or deploying a cluster. Bad things happen if you make the wrong 
choice. heh.

I keep a mental and written roadmap of the current strengths and 
weaknesses of LSF/PBS/SGE as used in life science environments. My 
knowledge of both Grid Engine and LSF is up-to-date but I wanted to make 
sure that I was still accurate about the current state of PBS since I 
don't use it or recommend it anymore.

Like you (and Chris) hit upon, the lack of array job functionality 
within PBS is one of the key things that can affect a selection 
decision. That and reliability plus day to day administrative overhead 
costs.

Regards,
Chris
