Don,

The PC scheduler will be very useful. I thought a couple of additional features that would be useful:

1. The version string comparison is tricky. It would be useful to have a way to handle it easily. If we simply use string comparison, like version >= 3.10.4, it would match 3.2.4 as well.

2. Currently, the scheduler chooses a node using "AND" operation with constraints. If we can apply "OR" operation somehow, it would be useful. For example, os == RedHat OR os == Ubuntu. This would be also a workaround for the first issue by using version == 3.10.4 OR version == 3.10.5.

Thanks,

Joseph

As promised at the meeting Thurs. I've attached a writeup of the Proof of Concept scheduler I created that offers that same functionality as the Abstract Scheduler but implements things through two new tables in the DataBase.  I implemented this scheduler based upon the Cactus release and it is fully functional but we didn't do any performance analysis on it.

Would be very interested in any questions/comments/epithets anyone has about this idea.
