Abstract: A computer system comprising multiple nodes, each node comprising a plurality of processors and a local cache hierarchy, suppresses local cache coherency of a node operations or global cache coherency operations between nodes based on the coherency request being a global or local request, and the state of the cache line at the node.

Abstract: An electronic package incorporating a heat-generating element which is thermally coupled to a heat-sinking member, through the utilization of a predetermined thermally conductive material, and wherein all of these components are placed in compression during package operation so as to resultingly improve the thermal performance of the electronic package. A method is set forth of improving the thermal performance of an electronic package through the intermediary of compressive forces being generated between the package components during package operation.
