Virtualization is a common strategy for improving the utilization of existing computing
resources, particularly within data centers. However, its use for high performance computing …

As the size of supercomputers increases, the probability of system failure grows
substantially, posing an increasingly significant challenge for scalability. It is important to …

Motivation Scientists increasingly rely on intelligent information systems to help them in their
daily tasks, in particular for managing research objects, like publications or datasets. The …

As machines increase in scale, many researchers have predicted that failure rates will
correspondingly increase. Soft errors do not inhibit execution, but may silently generate …

There is a clear trend towards using cloud resources in the scientific or the HPC community,
with a key attraction of cloud being the elasticity it offers. In executing HPC applications on a …

This book highlights the use of Charm++ in a wide variety of scientific and engineering
fields. It emphasizes the adaptivity, asynchrony, and message-driven execution of Charm++ …

The fat-tree topology is one of the most commonly used network topologies in HPC systems.
Vendors support several options that can be configured when deploying fat-tree networks on …

Present days cores composing a system-on-chip might be interconnected by means of both
dedicated channels or shared buses. Nevertheless, future systems will have strong …

A low-diameter, fast interconnection network is going to be a prerequisite for building
exascale machines. A two-level direct network has been proposed by several groups as a …

Parallel programming is certainly more difficult than sequential programming because of the
additional issues one has to deal with in a parallel program. One has to decide what …
