Actually my program is very simple MPI program "Hello World" which just prints rank of each processor and then terminates. When I run my program on a single processor machine with e.g 4 processors (oversubscribing) it shows:
Hello world from processor with rank 0 Hello world from processor with rank 3 Hello world from processor with rank 1 Hello world from processor with rank 2 but when I use my remote machines everything just stops when I run the program. No I do not use any queuing system. I simply run it like this: mpirun -np 4 --hostfile hosts ./hw and then it just tops until I terminate it manually. As I said, I monitored all machines (master+2 slaves) and found out that in all machines, "orted" daemon starts when I run the program, but after few seconds the daemon is terminated. What can be the reason?
