> both take a bit more time to customize for things > like consumable resources and parallel environments I think SGE is better, since with OpenPBS, you need to recompile in order to add a comsumable resource to the cluster. I used to play with PBS for a short while and then switched, mainly due to -- 1. there is not much failover features in PBS. If your master node dies, then your cluster stops running. SGE has 1 or more shadow masters, which can take over if the master fails. 2. PBS does not scale (there is not much improvement, I still receive mail complaining about this) I used to submit 30K jobs to see "what would happen", but SGE did not crash. The emails on PBS lists complain about PBS not being able to handle large number of jobs (5K) Also, if one of your execution node dies, PBS server sometimes hangs, waiting for timeout. This does not happen to SGE, and SGE is smart enough to reschedule the job to another machine. (It assumes the job is lost) > I believe PBSpro eventually folds improvements into > OpenPBS, so that might not be seen as that great of > a benefit. There are enough things that PBSPro has but is missing in OpenPBS. (mainly my opinion, but also the reactions from the mailing-list) The final thing I like about SGE is that Sun is willing to improve it, but it is open enough that you can go for other companies to ask for support. This is the real open source model that I want. -Ron __________________________________________________ Do You Yahoo!? Yahoo! Health - your guide to health and wellness http://health.yahoo.com
