Abstract

A method and apparatus for re-utilizing partially failed compute resources in a massively parallel super computer system. In the preferred embodiments the compute node comprises a number of clock domains that can be enabled separately. When an error in a compute node is detected, and the failure is not in network communication blocks, a clock enable circuit enables the clocks to the network communication blocks only to allow the partially failed compute node to be re-utilized as a network resource. The computer system can then continue to operate with only slightly diminished performance and thereby improve performance and perceived overall reliability.
