Show moreA system, method, and set of protocols for dynamic group communication are provided for enabling dynamic process migration and dynamic group membership management. A process in a group receives and distributes a migration signal. Group communication continues while the processes in the group asynchronously reach a global superstep and then a synchronization point. The processes then spawn a new process on a new device and update group membership information. The new process operates in continuous execution with the new group.

Show moreA method and apparatus for prefetching data from memory for a multicore data processor. A prefetcher issues a plurality of requests to prefetch data from a memory device to a memory cache. Consecutive cache misses are recorded in response to at least two of the pluarlity requests. A time between the cache misses is determined and a timing of a further request to prefetch data from the memory device to the memory cache is altered as a function of the determined time between the two cache misses.
