Hi Team, I am compiled the OpenFoam-1.7.1,openFoam-2.2.1,OpenFoam-2.2.2 versions. All the versions same problem that some times I am able to run simpleFoam 8,16,32,64,80 cores but some times it will get hang no messages will come. My observervation is that when I am running successfully the orted process in the node will start as single.(it means 8nodes means 8 orted process it will show) When I am not able to run,hangup the i verified that the orted processes in the node are more than one in few of the nodes(total it will be >8 for 8 nodes)
