ABSTRACT:
A computer system according to an example of the invention comprises SPEs and a global memory. The SPEs include a running SPE and an idling SPE. The running SPE and the idling SPE each have a processor core, local memory and DMA module. The local memory of the idling SPE stores data stored in the global memory and used by the processor core of the running SPE, before the data is used by the processor core of the running SPE. The DMA module of the running SPE reads the data from the local memory of the idling SPE, and transfers the data to the processor core of the running SPE.
