The distributed computing notion extends ideas used in the SETI project. Each node on the net emulates a single core, and, according to an INQ reader knowledgeable about this stuff, each machine is a core n one giant single processor.
The concept is staggering in its ambition and the team realise this, dubbing the release version Zero and looking for community support.
The initial release of the software is on Sourceforge under the file name WALLS-one-core-net-0.tar.gz. µ
