Designing Next-Generation Massively Multithreaded Architectures for Irregular Applications

We present a new scheme for evaluating the performance of multithreaded computers and demonstrate its application to the Cray MTA-2 and XMT supercomputers. Our scheme is based on the concept of clock cycles per element, \documentclass{article}\footskip=...

Distributed-memory machines have proved successful for many challenging numerical programs that can be split into largely independent computation-intensive subtasks requiring little data exchange (although the amount of exchanged data may be large). ...
