We need large arrays so we need 64 bit fortran code. We have been using the 32 bit metis library (C code supplied as a Windows library) and it appears large arrays may not be an issue for these library routines. Can we use the 32 bit library while creating a 64 bit fortran .exe?

No, all .obj must have matching /machine tags. If you bypass that check some way, your .exe will hang at run time.

That is what I was going to assume, but thought it was worth confirming.
Thanks
