FuPerMod: a software tool for the optimization of data-parallel applications on heterogeneous platforms

Optimization of data-parallel applications for modern HPC platforms requires partitioning the computations between the heterogeneous computing devices in proportion to their speed. Heterogeneous data partitioning algorithms are based on computation performance models of the executing platforms. Their implementation is not trivial as it requires: accurate and efficient benchmarking of computing devices, which may share resources and/or execute different codes; appropriate interpolation methods to predict performance; and advanced mathematical methods to solve the data partitioning problem. In this paper, we present FuPerMod, a software tool that addresses these implementation issues and automates the development of data partitioning code in data-parallel applications for heterogeneous HPC platforms.
