Hi, Hal - > How is this being observed/measured ?
Host A, B, with 4x DDR both connected to Flextronic switch. A single process of ibv_read_bw gives about 1415MB /s average bandwidth. Two concurrent process report 714.45 MB/s each, dead even. Now if I bump up one process with a different SL, then I expect to see shaping to take place. Please let me if the scenario makes sense. > Yes, 8 VLs should be supported in your subnet.

I will poke for more info with suggested commands by Sasha. > > A related question is, if I modify qos setting in SM, do I need to > > restart SA on each hosts for it to see the changes?

I mean client SA. yes, I understand OpenSM needs to be restarted. > BTW, which OpenSM are you running ? OFED 1.1 based. thanks - Oliver _______________________________________________ openib-general mailing list [email protected] http://openib.org/mailman/listinfo/openib-general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
