What performance improvement is offered by memory interleaving? Single- and Multichannel Memory Modes. Download PDF. Software prefetch is an important strategy for improving performance on the Intel Xeon Phi coprocessor. A computer system uses 5-way interleaved memory, with interleaving performed on an 8-byte word basis (incrementing the address by 8 goes to the next higher bank, with wrap-around to bank 0). This is responsible for speeding up the entire process. In order to support this, the CPU must be able to switch threads on every clock cycle. ; Job suggestion you might be interested based on your profile.
