User-level threads have been widely adopted as a means of achieving lightweight concurrent execution without the costs of OS-level threads. Nevertheless, the costs of managing user-level threads represent a performance barrier that dictates how fine

In this article, we investigate contention management in lock-based thread-safe MPI libraries. Specifically, we make two assumptions: (1) locks are the only form of synchronization when protecting communication paths; and (2) contention occurs, and t

Efforts to mitigate lock contention from concurrent threaded accesses to MPI have reduced contention through fine-grained locking, avoided locking altogether by offloading communication to dedicated threads, or alleviated negative side effects from c

International audience; 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 respect to cost and flexibility. Current state-o

Advanced Thread Synchronization for Multithreaded MPI Implementations

Publikováno v: CCGrid

Concurrent multithreaded access to the Message Passing Interface (MPI) is gaining importance to support emerging hybrid MPI applications. The interoperability between threads and MPI, however, is complex and renders efficient implementations nontrivi
