If you use your G4 for numerical computation, this may be of interest to you. I've had a page with computing tools for OS X for some time now. I just added some information and analysis on how one could harness the full power of a dual G4 for numerical work.

The page is about using AltiVec and using both processors in parallel for C and Fortran codes. The speed gain upon using both parallelization and vectorization is huge. On my tests, it varied between 4x and 10x improvement!
