WMTools - Assessing Parallel Application Memory Utilisation at Scale

Executive Summary

The divergence between processor and memory performance has been a well discussed aspect of computer architecture literature for some years. The recent use of multi-core processor designs has, however, brought new problems to the design of memory architectures - as more cores are added to each successive generation of processor, equivalent improvement in memory capacity and memory sub-systems must be made if the compute components of the processor are to remain sufficiently supplied with data. These issues combined with the traditional problem of designing cache-efficient code help to ensure that memory remains an on-going challenge for application and machine designers.
