Hello,<br>
<br>
<br>
I'm using OFED-3.5-1 with SL-6.4 (I had to do some minor patching to get it working on 2.6.32-358.14.1.el6.x86_64 kernel due to double export of __pskb_copy).<br>
<br>
OpenMPI give known warning about limit of registrable memory (below). But in current modules there is no "log_num_mtt" parameter to tune.<br></blockquote><div> </div><div>Which HCA are you using ?</div><div> </div>

<br>
Just in case, My hard and soft limits for maximal locked memory are unlimited.<br>
<br>
What should be procedure with latest OFED then?<br>
<br>
Thank you,<br>

WARNING: It appears that your OpenFabrics subsystem is configured to only<br>

run with erratic performance, hang, and/or crash.<br>
<br>
This may be caused by your OpenFabrics vendor limiting the amount of<br>

relevant Linux kernel module parameters that control how much physical<br>

physical memory on your machine.<br>
