Designing Next-Generation Massively Multithreaded Architectures for Irregular Applications
August 2012 (vol. 45 no. 8)
pp. 53-61

Massively multithreaded architectures like the Cray XMT address the needs of irregular data-intensive applications better than commodity clusters. A proposed evolution of the XMT integrates multicore processors and next-generation interconnects, along with memory reference aggregation to optimize network utilization. The featured Web extra is a video interview with Center for Adaptive Supercomputing Software-Multithreaded Architectures (CASS-MT) Project Director John Feo, who discusses irregular applications and research on massively multithreaded architectures.
