Not expected, no - but given how little it is used any more, I’m not surprised. I can take a quick gander and see if I can easily fix it. > On Jun 8, 2015, at 3:10 PM, David Shrader wrote: > > Hello All, > > I had a user report that orte-clean is hanging on him with Open

[OMPI users] orte-clean hang in 1.8.5

Hello All, I had a user report that orte-clean is hanging on him with Open MPI 1.8.5. Here are the steps I used to reproduce what he reported: %> which orte-clean /usr/projects/hpcsoft/toss2/moonlight/openmpi/1.6.5-gcc-4.4/bin/orte-clean %> mpirun -n 1

Re: [OMPI users] Building OpenMPI on Raspberry Pi 2

Jeff, Sorry - I was traveling for a week and didn't have to the RPi. What happens if you don't supply CCASFLAGS at all? The output from "make" is below. It died when it tried to compile atomic-local. It says the processor doesn't support ARM mode "dmb". Thanks! Jeff pi@raspberrypi

[OMPI users] CygWin compilation of OpenMPI-1.8.5

Greetings, CygWin is interesting intermediating environment between Windows and Linux-like architectures, and the OpenMPI project is good platform for enabling parallel calculations. Here is my OpenMPI building experience with some problems encountered (with up-to-date CygWin & OpenMPI): 1)
