The Long and Winding Road Toward Efficient High-Performance Computing

Résumé

The major challenge to Exaflop computing, and more generally, efficient high-end computing, is in finding the best "matches" between advanced hardware capabilities and the software used to program applications, so that top performance will be achieved. Several benchmarks show very disappointing performance progress over the last decade, clearly indicating a mismatch between hardware and software. To remedy this problem, it is important that key performance enablers at the software level-autotuning, performance analysis tools, full application optimization-are understood. For each area, we highlight major limitations and most promising approaches to reaching better performance and energy levels. Finally, we conclude by analyzing hardware and software design, trying to pave the way for more tightly integrated hardware and software codesign.
