The OpenSSI framework rearranges processes for easy and transparent clustering.

A Single System Image (SSI) cluster is a collection of separate computers that appear as a single multi-processor system. SSI clustering platforms are typically implemented at the kernel level.

These processes then pass transparently among the computers in the cluster.
