I don’t know what you put in that log file, but it was an executable and I’m not feeling that trusting :-)
I’m afraid there isn’t enough debug output there to really tell anything. From what little I can see, I’m guessing that the application ran fine and you got the usual “hello” output and the helloworld process exited safely - is that correct? And so it is solely mpirun that is failing to cleanly terminate? > On Nov 24, 2014, at 11:24 PM, Allan Wu <al...@cs.ucla.edu> wrote: > > Hello everyone, > > I have cross-compiled OpenMPI for an embedded ARM Linux.
