I worked at Locus back in the 90s, when this technology was part of the AIX 1.2/1.3 family. The basic architecture allowed for heterogeneous clusters (i386 and i370 -- PC's and IBM Mainframes all running on the same global filesystem.) Pretty sure you couldn't migrate processes to a machine with a different architecture though. It was awesome to be able to "kill -MIGRATE" a long-running make job to somebody else's idle workstation, or use one of the built-in shell primitives to launch a new job on the fastest machine in the cluster "fast make -j 10 gcc". edit: spelling
