As predicted by Gordon E. Moore in 1965, the performance of computer processors
increased at an exponential rate. Nevertheless, the increases in computing speeds of single …

Single processing units have now reached a point where further major improvements in their
performance are restricted by their physical limitations. This is causing a slowing down in …

Scientific computation has come into its own as a mature technology in all fields of science
and engineering. Never before have we been able to accurately anticipate, analyze, and …

Supercomputing systems have made great strides in recent years as the extensive
computing needs of cutting-edge engineering work and scientific discovery have driven the …

In the last decade, parallel computing technologies have transformed highperformance
computing. Two trends have emerged: massively parallel computing leading to exascale on …

Exascale systems will present programmers with many challenges. The authors review the
parallel programming models that are appropriate for such systems and the challenges that …

The development of an exascale computing capability with machines capable of executing
O (10 18) operations per second by the end of the decade will be characterized by …
