Code hangs when variables value increases


I have the latest intel mpi 5.1, together with the fortran compiler in my own ubuntu linux. I tried to run my code but it hangs. It was working fine in different clusters before.

How to submit jobs in Microsoft HPC 2012 Pack?

Dear all,

I have a cluster contains 10 calculation nodes named N01~N10, in N01 the Windows server 2012 and Microsoft HPC 2012 Pack installed and in other nodes the Windows 7 64bit and Microsoft HPC 2012 Pack installed. I created a domain in N01 and added all other nodes to this domain. In HPC 2012, I also set N01 as the head node and added all other nodes to the head node. In 'node management' I can find that all N01~N10 are online.
