Abstract

The major performance bottleneck of the parallel Fourier method on distributed memory systems is the network communication cost. In this study, we investigate the potential of using non-blocking all-to-all communications to solve this problem by overlapping computation and communication. We present the runtime comparison of a 3D seismic modeling problem with the Fourier method using non-blocking and blocking calls, respectively, on a Linux cluster. The data demonstrate that a performance improvement of up to 40% can be achieved by simply changing blocking all-to-all communication calls to non-blocking ones to introduce the overlapping capability. A 3D reverse-time migration result is also presented as an extension to the modeling work based on non-blocking collective communications.
