I'm having a problem using OpenMPI under PBS Pro 10.4. I tried both 1.4.3 and 1.5.3, both behave the same. I'm able to run just fine if I don't use PBS and go direct to the nodes. Also, if I run under PBS and use only 1 node, it works fine, but as soon as I span nodes, I get the following:

Does anyone have an update to this, and has anyone been able to run successfully using recent versions of PBSPro? I've also contacted our rep at Altair, but he hasn't responded yet. Thanks, Justin.
