 This is for multiple-node runs with ''charmrun'' as the distributed component and ''namd2'' on each compute node. We have found most runs are faster with the ''+setcpuaffinity +isomalloc_sync'' options. charmrun ''++ppn'' should match PBS ''ppn=''. This is for multiple-node runs with ''charmrun'' as the distributed component and ''namd2'' on each compute node.
