New paper “ScalOMP: analyzing the Scalability of OpenMP applications” to be presented at IWOMP’19.
Anton Daumen will present his work “ScalOMP: analyzing the Scalability of OpenMP applications” at IWOMP’19. His paper is available online: https://hal.archives-ouvertes.fr/hal-02179726 Abstract : Achieving good scalability from parallel codes is becoming increasingly difficult due to the hardware becoming more and more complex. Performance tools help developers but their use is sometimes complicated and very iterative. In […]
New paper “Using differential execution analysis to identify thread interference”. To appear in IEEE Transactions on Parallel and Distributed Systems
Abstract Understanding the performance of a multi-threaded application is difficult. The threads interfere when they access the same shared resource, which slows down their execution. Unfortunately, current profiling tools report the hardware components or the synchronization primitives that saturate, but they cannot tell if the saturation is the cause of a performance bottleneck. In this […]
