If you have 4 cores per WN then:
GlueHostMainMemoryRAMSize: 8182
GlueHostArchitectureSMPSize: 4
- assuming that you don't explicitly kill jobs, i.e. potentially a job
could get 8 Gb to itself if nothing else were running. And also assuming
that you run a maximum of 4 jobs per node - if you allow more it would
probably be better to make SMPSize the number of jobs, even though
strictly speaking it's a hardware value. (Glue 2 should hopefully do
this better, multi-core CPUs weren't an issue when Glue 1 was defined!)
