PROCESSORS ---------- Set to specify how many process slots this test requires. If not set, the default is ``1`` processor. Denotes the number of processors that this test will require. This is typically used for MPI tests, and should be used in conjunction with the :command:`ctest_test` ``PARALLEL_LEVEL`` option. This will also be used to display a weighted test timing result in label and subproject summaries in the command line output of :manual:`ctest(1)`. The wall clock time for the test run will be multiplied by this property to give a better idea of how much cpu resource CTest allocated for the test. See also the :prop_test:`PROCESSOR_AFFINITY` test property.
