HP/UX 10.x has a memory limit of 944 MB per process. This is a fundamental limit of the OS and there is no way to increase it. I believe the limit is 2 GB for 32 bit processes on 11.0. For this reason we use Suns for computations that require large amounts of memory. Under Solaris 2.6 and later a 32 bit process can address up to 3.5 GB of memory.
