Re: [OMPI devel] accessors to context id and message id's

If I understand correctly your question, then we don't need any extension. Each request has a unique ID (from PERUSE perspective). However, if I remember well this is only half implemented in our PERUSE layer (i.e. it works only for expected requests). This should be quite easy to fix, if s

This is extremely tricky to do. How do you know which environment variables to forward (foo in this case) and which not to (hostname). SLURM has a better chance, since it's linux only and generally only run on tightly controlled clusters. But there's a whole variety of things that shouldn't b

[OMPI devel] Environment forwarding

Hi, After talking with Torsten today I found something weird. When using the SLURM pls we seem to forward a user's environment, but when using the rsh pls we do not. I.e.: [tprins@odin ~]$ mpirun -np 1 printenv |grep foo [tprins@odin ~]$ export foo=bar [tprins@odin ~]$ mpirun -np 1 printenv |gr

[OMPI devel] accessors to context id and message id's

2007-11-05 Thread Terry Dontje
Currently in order to do message tracing one either has to rely on some error prone postprocessing of data or replicating some MPI internals up in the PMPI layer. It would help Sun's tools group (and I believe U Dresden also) if Open MPI would create a couple APIs that exoposed the following:
