In the past few decades, a number of user-level threading and tasking models have been
proposed in the literature to address the shortcomings of OS-level threads, primarily with …

We present a unified fault-tolerance framework for task-parallel message-passing
applications to mitigate transient errors. First, we propose a fault-tolerant message-logging …

In this paper, we present NanoCheckpoints which is a lightweight software-based
checkpoint/restart scheme for task-parallel HPC applications. We leverage OmpSs, a task …

Last-level caches (LLCs) bridge the processor/memory speed gap and reduce energy
consumed per access. Unfortunately, LLCs are poorly utilized because of the relatively large …

The popularization of multimedia content on the Web has arised the need to automatically
understand, index and retrieve it. In this paper we present ViTS, an automatic Video Tagging …

The current trend in development of parallel programming models is to combine different
well established models into a single programming model in order to support efficient …

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 …

We present DASHMM, a general library implementing multipole methods (including both
Barnes-Hut and the Fast Multipole Method). DASHMM relies on dynamic adaptive runtime …

In this paper, we explore data-driven execution of the adaptive fast multipole method by
asynchronously scheduling available computational tasks using Cilk, C++ 11 standard …

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 …
