We present a fault-tolerant protocol for task-parallel message-passing applications to
mitigate transient errors. The protocol requires the restart only of the task that experienced …

While checkpointing is typically combined with a restart of the whole application, localized
recovery permits all but the affected processes to continue. In task-based cluster …

The state-of-the-art checkpointing techniques are projected to be prohibitively expensive in
the Exascale era. These techniques are most often holistic in nature which prevents them to …

In this paper we propose a runtime-based selective task replication technique for task-
parallel high performance computing applications. Our selective task replication technique is …

We present a modular and scalable approach for automatically extracting actual
performance information from a set of FPGA-based architecture topologies. This information …

Current trends and projections show that faults in computer systems become increasingly
common. Such errors may be detected, and possibly corrected transparently, eg, by Error …

Memory reliability will be one of the major concerns for future HPC and Exascale systems.
This concern is mostly attributed to the expected massive increase in memory capacity and …

Various technological developments in the microprocessor world make modern computing
systems more vulnerable to soft errors than in the past, and consequently fault tolerance …

Exceptions and errors occurring within mission critical applications due to hardware failures
have a high cost. With the emerging Next Generation Platforms (NGPs), the rate of hardware …
