I guess the easiest way would be to simply build LibGeoDecomp with HPX support and uncommenting the test testManySteps() in libgeodecomp/src/parallelization/test/parallel_hpx_4_1/hpxdataflowsimulatortest.h. If you set the chunk size in the test to a high value, then it should exhaust that system's memory: HPXDataflowSimulator<DummyModel> sim(initializer, "testManySteps", 300000, true, 300000); You can limit the tests to be run in LibGeoDecomp by setting LIMIT_FLAGS in CMake: cd libgeodecomp4/build/ cmake -DLIMIT_TESTS=parallelization.test_parallel_hpx_4 .. make tests make check Cheers -Andi -- ========================================================== Andreas Schäfer HPC and Supercomputing Institute for Multiscale Simulation Friedrich-Alexander-Universität Erlangen-Nürnberg, Germany +49 9131 85-20866 PGP/GPG key via keyserver http://www.libgeodecomp.org ========================================================== (\___/) (+'.'+) (")_(") This is Bunny.
