Ethernet port is simply not up to this type of thing and becomes the main bottleneck. It was an interesting exercise to go through and the setup would almost certainly work nicely for MPI applications that are more in the vein of map-reduce type. Steve From: Steve O'Hara Sent: 24 January 20

node and see how it impacts performances. you can also run some standard MPI benchmark (osu, imb) and see if you get the performance you expect. Cheers, Gilles On Sunday, January 24, 2016, Steve O'Hara mailto:soh...@pivotal-solutions.co.uk>> wrote: Hi, I’m afraid I’m pretty

Hi, I'm afraid I'm pretty new to both OpenFOAM and openMPI so please excuse me if my questions are either stupid or badly framed. I've created a 10 Raspberry pi beowulf cluster for testing out MPI concepts and see how they are harnessed in OpenFOAM. After a helluva lot of hassle, I've got the
