Abstract:Abstract. This article presents the C++ library vShark which reduces the intranode communication overhead of parallel programs on clusters of SMPs. The library is built on top of message-passing libraries like MPI to provide thread-safe communication but most importantly, to improve the communication between threads within one SMP node. vShark uses a modular but transparent design which makes it independent of specific communication libraries. Thus, different subsystems such as MPI, CORBA, or PVM could also be… Show more
