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 …

We expect that the size and the complexity of future supercomputers will increase on their
path to exascale systems and beyond. Therefore, system software has to adapt to the …

Linux®, or more specifically, the Linux API, plays a key role in HPC computing. Even for
extreme-scale computing, a known and familiar API is required for production machines …

Extreme degree of parallelism in high-end computing requires low operating system noise
so that large scale, bulk-synchronous parallel applications can be run efficiently. Noiseless …

Performance isolation is emerging as a requirement for High Performance Computing (HPC)
applications, particularly as HPC architectures turn to in situ data processing and application …

Today's HPC systems use two mechanisms to address main-memory errors. Error-correcting
codes make correctable errors transparent to software, while checkpoint/restart (CR) …

OS-capable embedded systems exhibiting a very low power consumption are available at
an extremely low price point. It makes them highly compelling in a datacenter context. In this …

Turning towards exascale systems and beyond, it has been widely argued that the currently
available systems software is not going to be feasible due to various requirements such as …

OS-capable embedded systems exhibiting a very low power consumption are available at
an extremely low price point. It makes them highly compelling in a datacenter context. We …

Multi-kernels leverage today's multi-core chips to run multiple operating system (OS)
kernels, typically a Light Weight Kernel (LWK) and a Linux kernel, simultaneously. The LWK …
