Hi David,

here at ITC-irst we have made some experiments with GRASS on openMosix.
As we were doing image classification with i.smap on hundreds of images,
we could distribute these jobs across the openMosix nodes. Worked with
some tricks (AFS file system was needed etc).

You can find a bit in our Bangkok 2004 paper:
