Abstract

See full text

Poisoning of specific memory locations as a process when a part of a multiprocessor computer system becomes faulty leads to ability to isolate specific data owned by individual failing units even in a shared memory area. Also continuous processing by non-failing units is allowable. A support processor handles non-immediate problems and allows resetting of memory locations formerly owned by failed units.
