Hi,
I am using CAM3.0 in the stand-alone version. I am trying to install in on a machine that has the following properties:
1)SGI Altix XE320-based cluster with 1280 cores connected with Infiniband, running the Scientific Linux operating system.
2)login node, storage server and 160 compute nodes providing 1280 processor cores for computations. Each 8-core compute node has 2 sockets, each containing an Intel Xeon L5420 quad-core processor, running at 2.5 GHz. Each compute node has 16 GB of memory (DDR2 RAM) that can be shared among the 8 cores on that node.
3)The compute nodes are connected with double data rate (DDR) infiniband (providing an aggregate 20 Gb/s) with 2 to 1 blocking, using a 288-port Voltaire Grid Director ISR 2012 switch.
Considering these characteristics, should I configure CAM to run as MPI, openMP or hybrid mode to obtain the best performances?
Thank you very much,
Gabrielle
