Thanks! It fixes the problem with tcp. Best regards, Elena On Thu, Nov 6, 2014 at 10:44 AM, George Bosilca wrote: > I pushed a slightly better patch for the TCP BTL > (54ddb0aece0892dcdb1a1293a3bd3902b5f3acdc). The correct scheme would be to > OBJ_RETAIN the proc once it

Re: [OMPI devel] simple_spawn test fails using different set of btls.

I pushed a slightly better patch for the TCP BTL (54ddb0aece0892dcdb1a1293a3bd3902b5f3acdc). The correct scheme would be to OBJ_RETAIN the proc once it is attached to the btl_proc and release it upon destruction of the btl_proc. However, for some obscure reason this doesn't quite works, as the

Ralph, i updated the MODEX flag to PMIX_GLOBAL https://github.com/open-mpi/ompi/commit/d542c9ff2dc57ca5d260d0578fd5c1c556c598c7 Elena, i was able to reproduce the issue (salloc -N 5 mpirun -np 2 is enough). i was "lucky" to reproduce the issue : it happened because one of node was misconfigured

Re: [OMPI devel] simple_spawn test fails using different set of btls.

Elena, the first case (-mca btl tcp,self) crashing is a bug and i will have a look at it. the second case (-mca sm,self) is a feature : the sm btl cannot be used with tasks having different jobids (this is the case after a spawn), and obviously, self cannot be used also, so the behaviour and

[OMPI devel] simple_spawn test fails using different set of btls.

Hi, It looks like there is a problem in trunk which reproduces with simple_spawn test (orte/test/mpi/simple_spawn.c). It seems to be a n issue with pmix. It doesn't reproduce with default set of btls. But it reproduces with several btls specified. For example, salloc -N5
