Yes, It works fine without shared memory. I thank you Ralph. I will check the code for logical mistakes, otherwise I choose the option suggested by you. 2011/3/26 Ralph Castain > Your other option is to simply not use shared memory. TCP contains loopback > support, so you can run with just > > -

Your other option is to simply not use shared memory. TCP contains loopback support, so you can run with just -mca btl self,tcp and shared memory won't be used. It will run a tad slower that way, but at least your app will complete. On Mar 26, 2011, at 2:30 PM, Reuti wrote: > Am 26.03.2011 u

Yes, the syntax is wrong in the email, but I write it correctly when I launch mpirun. When some communicating processes are on the same node the application don't terminate, otherwise the application terminate and its results are correct. My OpenMPI version is 1.2.7. 2011/3/26 Ralph Castain > >
