Hello. The &env_max_procs() does not seem to work in my setup. MTT is run from within a PBS job which should be supported. If I set np in the configuration to a fixed value, tests run propperly. :/
Here the config section: [Test run] pass = &and(&cmd_wifexited(), &eq(&cmd_wexitstatus(), 0)) timeout = &max(30, &multiply(10, &test_np())) save_stdout_on_pass = 1 merge_stdout_stderr = 1 stdout_save_lines = 1000 np = &env_max_procs() #np = 64 specify_module = Simple [Test run: mpi_test_suite ] test_build = hlrs_mpi_test_suite include_section = Test run specify_module = Simple simple_pass:tests = mpi_test_suite And here the error message where np is empty during execution: Running with [ompi-nightly-v1.6] / [1.6.6a1r29300] / [gcc warnings] Using MPI Details [open mpi] with MPI Install [gcc warnings] >>> Using group_reports ### ### Total tests to run in this section: ### 1 test executable(s) ### 1 np value(s) ### 1 argv value(s) ### 1 test variant(s) ### 1 total mpirun command(s) to run ### *** WARNING: Test: mpi_test_suite -t "All,^io,^one-sided", np=, variant=1: FAILED Any idea where this problem comes from?
