Report on the parallelization of the MLfit benchmark using OpenMP and MPI

Abstract

This report describes the development of an MPI parallelization support on top of the existing OpenMP parallel version of the MLfit benchmark for a hybrid evaluation on multicore and distributed computational hosts. The MLfit benchmark is used at CERN openlab as a representative of data analysis applications used in the high energy physics community. The report includes the results of scalability runs obtained with several configurations and systems
