Do It Yourself
Recipe IconHow to Build an AppleSeed
       a one-page recipe for constructing a Macintosh cluster

Recommended software (what we use to keep 'em running):
"Most innovative commercial software" - IEEE Cluster 2001 Conference
Pooch IconPooch
       an application that assists in starting MacMPI_IP and MacMPI_X parallel executables

A fun way to test your system:
Parallel Fractal Demo IconAltiVec Fractal Carbon Demo (98 kB) 
       a MacMPI parallel graphics application demo which runs on an arbitrary number of G3s or G4s with OS 9 or X
fingerWith this program we've achieved 6 GFlop/sec on a cluster of four G4s!

Benchmarks
A cluster of Power Macs can give parallel performance comparable to a small MPP for certain problems:


UPDATE: A recent milestone has been achieved with AppleSeed:

A calculation containing 100 million multually interacting particles, which could only be done on the world's largest supercomputers 6 years ago, was completed using an 8-node Macintosh G4/450 cluster.  Read on...
