Since Rich was already unable to attend the July meeting, I would like to find a way to accommodate his schedule if possible. I'm not sure that it is critical that we have a meeting too hard on the heels of the Dec one, so perhaps something in Feb (or even March) makes the most sense. Giv

I'll answer this outside of Terry's reply so we can stay under George's page limit. :-)) I don't have any philosophical opposition to the idea. Indeed, there are places where I would potentially have some use for the btl's, perhaps as an alternative comm channel in the OOB. I will point out

[OMPI devel] orte_default_hostfile

2008-12-05 Thread Greg Watson
Hi, In 1.2.x, the rds_hostfile_path parameter pointed to openmpi-default- hostfile by default. This parameter has been replaced with orte_default_hostfile in 1.3, but now it defaults to . Was there any particular reason for the default value to change? Greg

[OMPI devel] Forwarding SIGTSTP and SIGCONT

2008-12-05 Thread Rolf Vandevaart
We have had requests to be able to suspend/resume MPI jobs within an SGE environment. SGE sends a signal (which is configurable) to mpirun to stop the job and another signal to resume it. To support this, I propose that we add support in the ORTE to catch SIGTSTP/SIGCONT and forward these t
