[Mauiusers] problem with maxnode & partitions

[Andrew J Caird]

I have a similar question; maybe some general clarification on MAXNODE 
and MAXPROC would help both Darrian and me.

I have a configuration that looks like:

USERCFG[DEFAULT]        PLIST=GENERAL  FSTARGET=10 MAXPROC=32
CLASSCFG[long] MAXNODE=96 PLIST=GENERAL PRIORITY=40
CLASSCFG[short] MAXNODE=64 PLIST=GENERAL PRIORITY=30
CLASSCFG[private1] PLIST=PRIVATE1 PRIORITY=60
CLASSCFG[private2] PLIST=PRIVATE2 PRIORITY=60

NODECFG[n001] PARTITION=GENERAL
...
NODECFG[n100] PARTITION=GENERAL
NODECFG[n101] PARTITION=PRIVATE1
...
NODECFG[n150] PARTITION=PRIVATE1
NODECFG[n151] PARTITION=PRIVATE2
...
NODECFG[n200] PARTITION=PRIVATE2

In English, I'm trying to say: for the 100 nodes in the GENERAL 
partition, no more than 96 can be used for long jobs, and no more than 
64 for short jobs; there are no such restrictions on PRIVATE1 or 
PRIVATE2; overall no one can run on more than 32 processors.  This seems 
to be working for me.

What I'd like to say, however, is that no one user can run on more than 
32 processors in the GENERAL partition, regardless of what they are 
doing in a PRIVATE partition, and that there are no such limits in the 
PRIVATE partitions.  In fact, does specifying PLIST=GENERAL in the 
USERCFG line mean I'm getting this today?  I haven't had a job mix that 
would test this.  Perhaps this is what Darrien needs?

I tried eliminating the MAXPROC=32 from the USERCFG line and adding this:

CLASSCFG[long] MAXNODE=96 PLIST=GENERAL PRIORITY=40 MAXPROC[USER]=32
CLASSCFG[short] MAXNODE=64 PLIST=GENERAL PRIORITY=30 MAXPROC[USER]=32

but it didn't seem to work.  The docs at 
http://www.clusterresources.com/products/maui/docs/6.2throttlingpolicies.shtml 
seem to imply that it should.

Thanks a lot for any insight.
