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?

We cannot possibly say without seeing the code.
