Addressing failures in exascale computing
We present here a report produced by a workshop on ‘Addressing failures in exascale computing’ held in Park City, Utah, 4–11 August 2012. The charter of this workshop was to establish a common taxonomy about resilience across all the levels in a computing system, discuss existing knowledge on resilience across the various hardware and software layers of an exascale system, and build on those re...
متن کاملThe Exascale Computing Project
E xascale computing—computing capability that can achieve at least a billion billion operations per second, 50 to 100 times more powerful than the nation’s fastest supercomputers in use today—is the next waypoint in high-performance computing (HPC). Achieving such speeds isn’t an easy task. To be useful to a wide spectrum of applications, in addition to peak speed, supercomputers need to have l...
متن کاملExascale Computing Technology Challenges
High Performance Computing architectures are expected to change dramatically in the next decade as power and cooling constraints limit increases in microprocessor clock speeds. Consequently computer companies are dramatically increasing on-chip parallelism to improve performance. The traditional doubling of clock speeds every 18-24 months is being replaced by a doubling of cores or other parall...
متن کاملAddressing Empathic Failures
Empathy is critical for social functioning, but it often wanes when it is needed most. Resulting empathic failures precipitate and worsen social conflict. Accordingly, conflict-reduction interventions prioritize developing empathy in order to achieve harmony. Recent research has indicated that such interventions can benefit from a more nuanced understanding of empathy. First, empathy is a multi...
متن کاملMultiscale computing in the exascale era
We expect that multiscale simulations will be one of the main high performance computing workloads in the exascale era. We propose multiscale computing patterns as a generic vehicle to realise load balanced, fault tolerant and energy aware high performance multiscale computing. Multiscale computing patterns should lead to a separation of concerns, whereby application developers can compose mult...
