Hi guys, Does someone know what the framework costs in term of latency ?
Righ now the latency I get with the openib btl is not great: 5.35 us. I was looking at what I could do to get it down. I tried to get openib be the only btl but the build process refused. On the other hand I am not sure it could even work at all, as whenever I tried at run-time to limit the list to just one transport (be it tcp or openib, btw), mpi apps would not start. Either way, I'm curious if it's even worth trying and if there's other cuts that can be made to shave off one us or two (ok, I'l settle for 1.5 :-) ) Any advice ? -- Jean-Christophe Hugly <j...@pantasys.com> PANTA
