When I declare a array of size REAL PNEW(10240*1024*51), it gives me negative image size. I do need a large size of array for very fine meshed computation. My question is since Intel Fortran 9.0 support 64-bit, I recently got a DELL PRECISION 380 (I think it is a 64-bit machine, correct me if I am wrong), my currentOS is windows 2000, do you think I need to upgrade to Windows XP-64 OS in order to be able to declare a large size of array which 64-bit machine can handle. Thanks.
