You need Linda to run G03 in parallel.

We run G03 on both Xeon and Opteron Beowulf Clusters and are very 
pleased with the Opterons.

This depends on whether you have the binary or source code version. If 
you use the binaries, you should follow Gaussian's recommendations. We 
run G03 (64-bit) on SuSE 9.0 and RedHat AS 4 without any problems.

Good luck! G03 can be finicky.
