Descripción
Sumario: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.
