Abstract:
1. A parallel computer system comprising: a plurality of nodes, each node comprising a memory; an entropy generation mechanism residing in the memory of at least one of the plurality of nodes, the entropy generation mechanism using at least one parity error in at least one of the memories in the plurality of nodes to add entropy to an entropy pool, wherein the entropy generation mechanism uses time and location of the at least one parity error to add entropy to the entropy pool, wherein the location comprises a chip serial number corresponding to a memory chip where a current parity error occurred; a random number generation mechanism residing in a memory of at least one of the nodes that uses the entropy pool to generate a random number; and a software agent residing in a memory of at least one of the nodes that receives the generated random number and transforms the generated random number to a form usable by the software agent.
