Is GRASS built for 32-bit (x86) or 64-bit (x86-64 aka amd64)? Running "file" on e.g. r.contour will tell you.
Glynn, No need to run file; this host is running a 32-bit CPU; the replacement machine is 64-bit.
A 32-bit process can't use more than 4 GiB of memory regardless of how much RAM or swap is available. The amount available to malloc() etc will be somewhat lower due to reservations for the kernel, stack, etc.
Thanks, I forgot about this since most of what I do does not require large amounts of memory. With the build configured with openmp will some grass modules use multiple processors on both 32- and 64-bit hosts?
