Abstract

In this paper we present some implementation details of a programming model - pCoR - that combines primitives to launch remote processes and threads with communication over Myrinet. Basically, we present the efforts we have made to achieve high performance communication among threads of parallel/distributed applications. The expected advantages of multiple threads launched across a low latency cluster of SMP workstations are emphasized with a graphical application that manages huge maps consisting of several JPEG images.
