An efficient parallel algorithm for O( N2) direct summation method and its variations on distributed-memory parallel machines

We present a novel, highly efficient algorithm to parallelize O( N 2) direct summation method for N-body problems with individual timesteps on distributed-memory parallel machines such as Beowulf clusters. Previously known algorithms, in which all processors have complete copies of the N-body system...
