I am trying to install a Molecular Dynamics program on a tru64 Compaq
system (e20 I believe). Program works fine until I give a memory
intensive command. Since I do not write the code my self but just give
commands as a script, I do not know what is happening in the code. It
says segmentation error. From some research I see that this occurs when
there is not enough memory available to the program.

1) Is it that an admin can change the amount of memory available to a
particular program? if yes, how?

2)The code basically is in Fortran and the program works well on
another Sun based server.
Any help would be appreciated.
