Description

When running on GPFS there may be significant memory used for memory buffer pool. This memory should be subtracted from the total memory available to the node. Actually, sum up all memory used up by processes owned by UID < max gid and subtract it from the total memory. The max gid is typically 500 but can be changed in ducc.properties.
