<div>We have not found that to be the case with HP-MPI, the latest HP-MPI 2.3 release supports up through OFED 1.4,</div>
<div>the previous release supported up through OFED 1.3.X. We have not experienced any challenges with support on older or new IB stacks</div>

<div>If you have a commercial application that bundled an older HP-MPI internally,</div>
<div>it is generally a snap to upgrade it or have it reference the latest system installed.</div>
