Make hostlist INI parameter more flexible #397

Open ompiteam opened 9 years ago

ompiteam commented 9 years ago

MTT has just one global hostlist for the [MTT] INI section, but there should also be a test run-specific way to set hostlist (the way there is for np). The workaround is to create two exec parameters, e.g.,

{{{ ... exec:foo = mpirun @hostlist1@ ... &test_executable() hostlist1 = --host wilma,fred exec:bar = mpirun @hostlist2@ ... &test_executable() hostlist2 = --host marge,homer ... }}}
