Rethinking Data Race Detection in RMA-Analyzer

Abstract

Supercomputers are capable of more and more computations, and nodes forming them need to communicate even more efficiently with each other. Thus, other types of communication models gain traction in the community. For instance, the Message Passing Interface (MPI) proposes a communication model based on one-sided communications called the MPI Remote Memory Access (MPI-RMA). Thanks to these operations, applications can improve the overlap of communications with computations. However, one-sided communications are complex to write since they are subject to data races. Tools trying to help developers by providing a data race detection for one-sided programs are thus emerging. This paper rethinks an existing data race detection algorithm for MPI-RMA programs by improving the way it stores memory accesses, thus improving its accuracy and reducing the overhead at runtime.
