On my test runs (wrf run just long enough to go beyond the spinup influence) On just 6 of the the old mlx4 machines I get about 00:05:30 runtime On 3 mlx4 and 3 qib nodes I get avg of 00:06:20 So the slow down is about 11+%When this is a full run 11% becomes a evry long time. This has held for some longer tests as well before I went to ofed 1.6.

I thought I would try one other test I had set up first. I went to OFED 1.6 and it started running with no errors. It must have been an OFED bug. Now I just have the speed problem. Anyone have a way to make the mixture of mlx4 and qlogic work together without slowing down?What do you mean by "slowing down"?
