Re: [OMPI users] --preload-binary does not work

Looks like there is some strange interaction there, but I doubt I'll get around to fixing it soon unless someone has a burning reason to not use tree spawn when preloading binaries. I'll mark it down as something to look at as time permits. On Jun 6, 2014, at 4:28 PM, Ralph Castain

Yeah, it doesn't require ssh any more - but I haven't tested it in a bit, and so it's possible something crept in there. On Jun 6, 2014, at 12:27 PM, Reuti wrote: > Am 06.06.2014 um 21:04 schrieb Ralph Castain: > >> Supposed to, yes - but I don't know how much

Supposed to, yes - but I don't know how much testing it has seen. I can try to take a look On Jun 6, 2014, at 12:02 PM, E.O. wrote: > Hello > I am using OpenMPI ver 1.8.1 on a cluster of 4 machines. > One Redhat 6.2 and three busybox machine. They are all 64bit
