Abstract
The multi-node multiprocessor system with globally shared memory is partitioned into groups of nodes called error containment clusters of nodes or ECCNs. The nodes would be partitioned such that an ECCN resides on a column of nodes or a row of nodes. Within each ECCN there is coherent memory sharing. Between the ECCNs, the communication is through a messaging protocol. The memory within each node is also partitioned into protected and unprotected memory. Unprotected memory is used for messaging and protected memory is used for sharing. A failure in an error containment cluster would corrupt the memory within that cluster, specifically the protected memory within that cluster and also the unprotected memory used by that cluster to communicate with the other clusters. However, the other clusters could continue to run because their protected memory would be unaffected, and could continue to communicate through the remaining unprotected memory.
