[condor-users] Dynamically Changing Virtual Machine Settings

[Jess Cannata <jac67@xxxxxxxxxxxxxx>]

I run a seven-node dual-processor Beowulf cluster running Condor 6.4 on 
Linux. Each machine has1.5 GB of RAM.

The default virtual machine settings divides the physical RAM equally 
between the two processors (755 MB, see below). This is fine for most 
jobs. Unfortunately, I have a Parallel VASP job that will only run if 
one of the two processors can access the full 1.5 GB of RAM. Is there 
any way that I can dynamically/temporarily adjust the virtual machine 
settings in order to allocate the full 1.5 GB of RAM to one of the 
processors? I don't want the changes to be permamanent, nor do I want to 
have to modify Condor's config files each time. Is it possible to 
include these changes in a job submission file?

I've gone through the manual numerous times and I've searched the list. 
How have other dual processor running Condor users dealt with this?

Thanks.

Jess
