 each group may correspond to a process the test will spawn when executed.

+possible for that to test to run without any resource allocation (and without
+the corresponding
+:ref:`environment variables <ctest-resource-environment-variables>`)
+if the user does not pass a resource specification file. Passing this file,
+either through the ``--resource-spec-file`` command-line argument or the
+``RESOURCE_SPEC_FILE`` argument to :command:`ctest_test`, is what activates the
+resource allocation feature. Tests should check the
+``CTEST_RESOURCE_GROUP_COUNT`` environment variable to find out whether or not
+resource allocation is activated. This variable will always (and only) be
+defined if resource allocation is activated. If resource allocation is not
+activated, then the ``CTEST_RESOURCE_GROUP_COUNT`` variable will not exist,
+even if it exists for the parent ``ctest`` process. If a test absolutely must
+have resource allocation, then it can return a failing exit code or use the
+:prop_test:`SKIP_RETURN_CODE` or :prop_test:`SKIP_REGULAR_EXPRESSION`
+properties to indicate a skipped test.

 single cryptography chip. In total, 3 resource groups are specified for this
 test, each with its own unique requirements.
 
+Note that the number of slots following the resource type specifies slots from
+a *single* instance of the resource. If the resource group can tolerate
+receiving slots from different instances of the same resource, it can indicate
+this by splitting the specification into multiple requirements of one slot. For

+In this case, the single resource group indicates that it needs four GPU slots,

+still assign slots from the same GPU.)

 When CTest sets the :ref:`environment variables
