Available memory limitation?

[Hao He]

Hi, there.

Dynamically memory allocation used, I am running my Fortran code on a 8 node
PC cluster. My code worked well when I use part of the total memory,
roughly 500 MB of 2 GB. But when I tried to usa finer mesh, which means that
I have to create larger array and use more memory, the program failed at
initialization. Don't know why. Do you have any idea for this problem?
Appreciate for your help.

BTW, some info of my system:
Intel Xeon Processor, Red Hat 7.3, Intel Fortran Compiler 6.0, LAM/MPI
6.5.6.

Have a nice weekend.

Best,
Hao He
