We're running SGE v.6u8 and have configured it to use tight integration 
with MVAPICH (0.9.7-2). To enforce memory limits we are using the h_vmem 
-resource, however with MVAPICH the setting the limit with '-l h_vmem' 
causes processes to be killed even though only a fraction of the 
reserved memory is used. We have 4-core Opteron nodes with 8GB RAM and 
Mellanox InfiniHost III Ex HCA:s. Is there a way to work around this?
