We have the A1 release, and the cards work - that is we get decent
communication speeds between two nodes. But if more than two nodes are
involved in calculations the speed goes down drastically (sometimes to
a complete stop). (This specific application runs with good
performance on other beowulfs.)
We are using the latest via-rhine from http://www.scyld.com/, but in
reference to the comment above we wonder if the lousy performance can
be a result of the DFE-530TX cards? Or is it likely something else is
causing this kind of problem? (And if we have to by new cards, would
the 3c905b-tx be a good choice?).
