| BIDM.Asset.Abstract | This library is based on MPICH, a widely used MPI implementation, but the collective communication primitives use new algorithms, optimized for wide area systems. The basic as sumption is that the wide area system is hierarchically structured. We expect a computational grid to consist of many parallel com puters connected by wide area networks. We use the term cluster to denote a single parallel machine (which can be a network of workstations, an MPP, or an SMP). All nodes within a cluster are connected by a highspeed interconnect that is orders of magnitude faster than the wide area interconnect between clusters. Collective communication algorithms are usually designed for local area networks, which have a low latency. Wide area systems however, have a high latency (and a lower bandwidth) and the per formance of collective communication operations is dominated by the traffic over the wide area links. Thus, our algorithms are de signed to reduce traffic over the slow links, resulting in a markedly different communication structure. Our algorithms are wide area optimal in that an operation incurs only a single wide area latency, and every data item is sent at most once across each wide area link. | META |
