High performance computing will probably reach exascale in this decade. At this scale,
mean time between failures is expected to be a few hours. Existing fault tolerant protocols for …

Fault tolerance is becoming a major concern in HPC systems. The two traditional
approaches for message passing applications, coordinated checkpointing and message …

Fault-tolerance has been identified as a major challenge for future extreme-scale systems.
Current predictions suggest that, as systems grow in size, failures will occur more frequently …

The ever increasing number of processors used in parallel computers is making fault
tolerance support in large-scale parallel systems more and more important. We discuss the …

The wireless mobile ad hoc network (MANET) architecture is one consisting of a set of
mobile hosts capable of communicating with each other without the assistance of base …

In this paper, we present a high performance recovery algorithm for distributed systems in
which checkpoints are taken asynchronously. It offers fast determination of the recent …

Computing systems will grow significantly larger in the near future to satisfy the needs of
computational scientists in areas like climate modeling, biophysics and cosmology …

An important set of challenges emerge as the High Performance Computing (HPC)
community aims to reach extreme scale. Resilience and energy consumption are two of …

Sažetak A cluster federation is a union of clusters and is heterogeneous. Each cluster
contains a certain number of processes. An application running in such a computing …

In this paper, we analyze network recovery algorithms, which allow computer networks to
properly function in spite of failures. In this analysis, we use methods and tools of the theory …
