NAS Benchmark Issue - spawning processes across multiple nodes (EXIT CODE: 9)

Hi all,
I am using intel parallel studio 2015 on Intel(R) Xeon(R) CPU E5-2680 v3 (RHEL-6.5) and currently facing issues with an mpi based application(Nas Parallel Benchmark-BT). Though the issue seems application specific, I would like to have your opinions on methodology to debug/fix issues like these .

I was successful in testing the mpi setup as :-
 

[puneets@host01 bin]$ cat hosts.txt
host02
host03

[puneets@host01 bin]$ mpirun -np 4 -ppn 2 -hostfile hosts.txt ./hello
host02
host02
host03
host03

But when i try to run the application, I end up with:-

[puneets@host01 bin]$ mpirun -np 4 -ppn 2 -hostfile hosts.txt ./bt.E.4.mpi_io_full

===================================================================================
=   BAD TERMINATION OF ONE OF YOUR APPLICATION PROCESSES
=   PID 25799 RUNNING AT host03
=   EXIT CODE: 9
=   CLEANING UP REMAINING PROCESSES
=   YOU CAN IGNORE THE BELOW CLEANUP MESSAGES
===================================================================================
APPLICATION TERMINATED WITH THE EXIT STRING: Killed (signal 9)

Whereas, on single node, i am able to run the application as:-

[puneets@host01 bin]$ mpirun -np 4  ./bt.E.4.mpi_io_full

I am attaching the make.def and compilation log for your reference.
Any help/Hint will be very useful. Eagerly awaiting your replies.
