One-sided atomic reduction, also known as the accumulate operation, combines atomically a content of the local buffer with data at remote memory location. This operation has been included in the MPI-2 standard a, MPI_Accumulate. The current paper discusses two strategies for implementing one-sided atomic reduction called owner-computes and callercomputes. Performance of these two schemes has been investigated on the HP Alphaserver SC45 and HP zx-2600 clusters both equipped with the Quadrics Elan-3 network.
