As high-performance computing systems continue to grow in size and complexity, energy efficiency and reliability have emerged as first-order concerns. Researchers have shown that data movement is a significant contributing factor to power consumption on these systems. Additionally, rollback/recovery protocols like checkpoint/restart can generate large volumes of data traffic exacerbating the energy...
Increasing size and complexity of high performance computing systems have led to major concerns over fault frequencies and the mechanisms necessary to tolerate these faults. Based on expected increases in core counts (to at least on the order of millions) and expected increases in component complexities, it has been projected that system MTBF for future extreme scale systems will fall below 10 minutes...
The increasing size and complexity of high performance computing (HPC) systems have led to major concerns over fault frequencies and the mechanisms necessary to tolerate these faults. Previous studies have shown that state-of-the-field checkpoint/restart mechanisms will not scale sufficiently for future generation systems. Therefore, optimizations that reduce checkpoint overheads are necessary to...
