When I run OpenFOAM in parallel, I want to check the communication rate between nodes. How can I monitor this? By Eth, it is quite simple. But for infiniband, I have no idea how to monitor it... I am using ubuntu 2004 :-) Best, __________________ My OpenFOAM algorithm website: http://dyfluid.com By far the largest Chinese CFD-based forum: http://www.cfd-china.com/category/6/openfoam We provide lots of clusters to Chinese customers, and we are considering to do business overseas: http://dyfluid.com/DMCmodel.html
