Dear Kajal,
if you have a reasonable amount of memory on your workstation (my guess is that you need at least 8 GByte or RAM) and you are using GFORTRAN you might want to try to add manually the flag "-mcmodel-large" to FFLAGS and LDFLAGS. I am not sure it is going to make a difference but it is a easy test to do.
