C-program works fine interactively, but not on the SGE server
Greetings, I have a C-program that is made to implement a hidden Markov model on an input file. The program is very memory intensive.

I've installed it on my local server where I have an account and it compiles fine. The way they have the server set up is that you can either work interactively in a special queue or submit the jobs using SGE. The program works great, but slow, interactively and I really need to send it to one of the queues through SGE to have access to multiple and better nodes. The thing is, when I submit it that (or, interestingly enough, just nohup it while I am working on the interactive queue) the program just freezes at the beginning when it allocating the memory once it has read in the input file.

I've run the program before on servers that use batch-queuing software and I've nohup'd it with no problems (on another server). Here, unless the standard output is going to the screen it freezes interminably.

Any ideas?

rdma_xserver

RDMA_XSERVER(1) 						     librdmacm							   RDMA_XSERVER(1)

NAME

       rdma_xserver - RDMA CM communication server test program

SYNOPSIS

       rdma_xserver [-p port] [-c comm_type]

DESCRIPTION

       Uses the librdmacm to establish various forms of communication and exchange data.

OPTIONS

       -p port
	      Changes  the  port  number that the server listens on.  By default the server listens on port 7471.  -c communication type Specifies
	      the type of communication established with the client program.  extended reliable-connected XRC QPs.

NOTES

       Basic usage is to start rdma_xserver, then connect to the server using the rdma_xclient program.

       Because this test maps RDMA resources to userspace, users must ensure that they have available system resources and permissions.   See  the
       libibverbs README file for additional details.
