The server receives and stores all Rweight value, and all nodes are then sorted by their Rweight value. A smaller value of Rweight means a higher node priority, and therefore more jobs should be assigned to it, or more ﬁle chunks should be placed on it. In this algorithm, Rcpu is measured in GHz, and Rmem is measured in GB, while Rbandwidth is measured in 100Mbps. datasize are measured in GB. We deﬁne a threshold T hweight to distinguish overloaded nodes as follow, T hweight = ξ [max(Rweight [j]) − min(Rweight [j])] + min(Rweight [j]) (11) where ξ is an adjustment factor.
Generally speaking, it requires at least 2 ∗ O(logψ) MapReduce jobs to choose the initial centers. When logψ is enormous, we cannot put up with so many MapReduce jobs. Furthermore, in the above section, we have shown that MapReduce does not directly support the iterative operation and the more MapReduce jobs the more cost. As shown in Figure 1, the network cost of PSKM++ is small and there is m m only i=1 Ci + i=1 φXi (Uj ) in each iteration, but the I/O cost is huge because the whole input has to read twice.
As a result, considering the twelve most abundant elements in the universe plus fully ionized hydrogen and electrons, totally 181 extra variables need to be stored and another 181 advection equations need to be solved at every grid point. Except the increased computing workloads introduced by additional advection equations, it will use up to roughly 15 times of system memory more than the case without NEI, and the following high communication overhead between neighbor processes is unavoidable eithor.
