Recommended Minimum System Requirements

Processor: Intel Pentium 4, Celeron, Xeon, AMD Athlon, AMD Phenom II. AMD Phenom/Barcelona processors with B2 stepping are not currently supported. G09W runs in 32-bit mode on 64-bit processors.
Operating System: Microsoft Windows XP, Server 2003, Vista (Home Basic, Business and Ultimate)
Memory (RAM): 1 GB
Disk: 200 MB (G09W storage); and 500 MB or more (scratch space)

Multiprocessor and Cluster/Network Parallel Versions

The multiprocessor version of G09W is limited to 4 processors (or cores). Similarly, any individual node within a cluster/network parallel job can take advantage of at most 4 processors/cores (e.g., a parallel calculation across 2 dual quad-core computer systems will require 4 workers: 2 per system).
