A Parallel Computational Model of NHCBL Based on Cluster

Now,cluster is a fashionable platform for parallel computing.It has the common characteristic of any parallel computing.And that,it has itself particular characteristic-computational resource′s nondedicated on node,computational resource′s heterogeneous on node,sensitivity to communication between nodes.In allusion to the parallel computing based on cluster,we improve on NHBL model(Nondedicated Heterogeneous Barrier LogGP model),and bring forward NHCBL model(Nondedicated Heterogeneous Barrier Log GP model Considering Congestion).NHCBL model comparatively well and truly reflected not only the common characteristic of parallel computing,but also particular characteristic of the parallel computing based on cluster-computational resource′s nondedicated on node,computational resource′s heterogeneous on node,sensitivity to communication between nodes.NHCBL model is more comprehensive and practical than NHBL model.
