Re: [OMPI devel] Trunk broken with linear, direct routing
Just an update: I have fixed this problem. However, I will hold off checking it into the trunk until tomorrow. It will come in with the MPI-2 repairs to avoid code conflicts.

[OMPI devel] Trunk broken with linear, direct routing
Since this appears to have gone unnoticed, it may not be a big deal. However, I have found that multi-node operations are broken if you invoke the linear or direct routed modules. Things work fine with the default binomial routed module. I will be working to fix this - just a heads up. Ralph

[OMPI devel] Framework selection
I ran into something unexpected today relative to the selection of frameworks. It was totally unplanned, and may be an error on my part - or I may be expecting the incorrect behavior. However, since others may encounter it unexpectedly as well, I am sending this to the list. What I had done was: 1. set OMPI_MCA_routed=direct in my environment 2. (much later) executed: mpirun ... -mca routed binomial ... What happened was that mpirun selected the direct routed module, while my application procs selected the binomial module. This unfortunately doesn't generate a warning, but rather segfaults and/or hangs at some unpredictable time depending upon the invoked communication patterns. It was my understanding that the cmd line should override anything in the environment. Is this no longer true? I checked and orterun does indeed process the cmd line prior to invoking orte_init. Or did I inadvertently do something wrong here (other than the fact that I had forgotten the envar was set)? Thanks Ralph
