And maybe smpi from SimGrid <http://simgrid.gforge.inria.fr/>, if you can get or synthesize calibration data. The MPI (or its tuning) may be rather important compared with the fabric, and is rarely properly reported in benchmark results ☹. SimGrid, at least, can use different collective algorithms; I don't know about the alternatives, or to what extent these can model offloading and the various routing schemes in use. A comparison would be interesting if anyone has one. <https://ieeexplore.ieee.org/document/7877012> has results for different topologies and concludes that there's no generally best network. _______________________________________________ Beowulf mailing list, Beowulf@beowulf.org sponsored by Penguin Computing To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
