It was never committed to OMPI - it became stuck in a side branch when the developer graduated and took a job, and never came across. Given the age, I'd suspect that side branch is way out-of-date and probably would need some significant effort before it could be brought into the OMPI trunk,

The problem was not in the start but in the wait (hint: the status is set in the wait). The difference I guess is r27880, which seems not to be in the 1.8. So, the 1.8 is not returning the correct status for persistent inactive requests, but it does the right thing for MPI_PROC_NULL bound

r31524 is fixing this corner case. The problem was that persistent request with MPI_RPOC_NULL were never activated, so the wait* function was taking the if corresponding to inactive requests. George. On Thu, Apr 24, 2014 at 12:14 AM, Gilles Gouaillardet wrote: >

There seems to be an opportunity to still have heterogeneous environment in the future. http://www.enterprisetech.com/2014/04/23/ibm-google-show-power8-systems-openpower-efforts/ I don’t think it is fair to shift the burden on the original developer instead of the committer who broke a feature.

[OMPI devel] mosix patches

Hi! What is current status of mosix support in OpenMPI? I have tried patches from http://www.cs.huji.ac.il/wikis/MediaWiki/mosix/index.php/Process_migration_for_OpenMPI but without any success, even on 1.6 branch. With best regards, Pavel.

Hi George, Having looked again you're correct about the two 2buf reductions being wrong. For now, I've updated my patch of nbc.c to copy buf1 into buf3 and then do buf3 OP= buf2 (see below). Patching ompi_3buff_op_reduce to cope with user-defined operations is certainly possible, but I don't

Folks, Here is attached an oversimplified version of the MPI_Recv_init_null_c test from the intel test suite. the test works fine with v1.6, v1.7 and v1.8 branches but fails with the trunk. i wonder wether the bug is in OpenMPI or the test itself. on one hand, we could consider there is a bug
