Hi Joseph, > For whatever it is worth, Maui has some serious bugs when it is in > full use.
We had problems initially when we first used Maui on our big cluster. Most of them were fixed by increasing some limits in the include files. We also had a problem with some idle jobs not running (showstart would show they should run immediately, but they would not). This was fixed by commenting out some code. This was in a patch published on this list many years ago, but it never made it to a release. The bugs caused by the Torque 5 change in attribute format are really the show stoppers for us, hence my desire to fix them. The others bugs I can live with, for now. > I had Maui running for a VERY long time and it would behave > differently when it was mostly idle as when it was under heavy use - > we have thousands of cores. > > In my frustration I downloaded and enabled "moab" eval and as if by > magic all of the weirdness we were seeing in Maui went away over a > 2-month period.

Good for you, but Torque still needs a free alternative to Moab. pbs_sched is out of the question, unless it is heavily modified to add missing features like backfilling. Maui is the closest approximation to a usable free scheduler for Torque. It would be nice if users helped to fix the bugs instead of giving up, but I understand that users do not necessarly have time, skill or will to do so. -- Michel Béland, analyste en calcul scientifique [email protected] bureau S-250, pavillon Roger-Gaudry (principal), Université de Montréal téléphone : 514 343-6111 poste 3892 télécopieur : 514 343-2155 Calcul Québec (www.calculquebec.ca) Calcul Canada (calculcanada.ca) _______________________________________________ mauiusers mailing list [email protected] http://www.supercluster.org/mailman/listinfo/mauiusers
