Re: [OMPI users] problem with MPI_Comm_spawn in 1.6.5 but not 1.4.3 or 1.8.4

Appreciate it - but as I said in my prior note, we aren’t maintaining 1.6 any more, so an upgrade to 1.8 (which worked, as you noted) is in order > On Mar 13, 2015, at 8:23 AM, Chris Paciorek > wrote: > > And the promised attachment. > > On Thu, Mar 12, 2015 at 6:11 PM, Chris Paciorek > mail

Indeed sounds like a bug in 1.6.5, but we no longer maintain that series. I'm afraid an upgrade to the 1.8 series is the only solution. > On Mar 12, 2015, at 6:11 PM, Chris Paciorek > wrote: > > I'm having an issue with MPI_Comm_spawn not starting workers on the > nodes provided via -machinef

I'm having an issue with MPI_Comm_spawn not starting workers on the nodes provided via -machinefile or -host. This is occurring on Ubuntu 14.04/14.10 with openMPI 1.6.5. However, I do not have the problem on Ubuntu 12.04 with openMPI 1.4.3 nor is there a problem when I install openMPI 1.8.4 from so
