Faisal,
>From the information you've given I can't be a whole lot of help, but I would
suggest the following to start figuring out the problem:
1. Try running lamboot and running your program on a single node [something
like mpirun -n 1 /common/hello]
2. If this works, try again on multiple nodes
If any of these fail, please add '-v' to the mpirun command line and send the
output.
Also, are you using the provided mpicc to compile the program? What is the
output of 'ldd /common/hello'?
