we have a Cluster build on new AMD Hexacores (Six-Core AMD Opteron 2427) with
two Hexacores per Node. The cluster should mainly run NAMD
The 24 Nodes are connected to each other with DDR Infiniband.
So now my question:
Which Option should I choose when
1) Compiling charm with mpi (mvapich2) to run on >12Cores
2) Compiling a version that should perform best on one node <=12Cores
These are the Options Charm provides:
1) single-threaded [default]
2) multicore(single node only)
4) POSIX Shared Memory
Thanks a lot for any suggestions.
