What's probably happening is that Windows is trying to expand the swapfile and having a hard time of it - adding more RAM would help, but even so, you're pushing hard on the architectural limit of 32-bit Windows.<BR /><BR />If you need a program that large, start considering a 64-bit system such as Itanium 2.<BR /><BR />Steve Thu, 17 Apr 2003 02:13:58 GMT Steven_L_Intel1 2003-04-17T02:13:58Z https://community.intel.com/t5/Intel-Fortran-Compiler/Work-space-Computer-memory/m-p/813349#M44032 I'm running this code in which I establish the workspace needed and let's say :<BR /> lenw = 15*xtent*ytent*ztent<BR /> LenIW = 15*xtent*ytent*ztent<BR />So the code needs 15 times the number of nodes on my grid. The problem comes when I use a larger 3D domain let's say 500x500x500 this means the code would need a workspace of 1.875e9 and my computer freezes. Is this a RAM memory problem or how could I make this run?<BR /><BR />thank you<BR /> Thu, 17 Apr 2003 01:08:50 GMT https://community.intel.com/t5/Intel-Fortran-Compiler/Work-space-Computer-memory/m-p/813349#M44032 ecc26 2003-04-17T01:08:50Z https://community.intel.com/t5/Intel-Fortran-Compiler/Work-space-Computer-memory/m-p/813350#M44033 You're asking for an array almost 2GB in size.
