 <p>This option tells CTest to load in a configuration script which sets
 a number of parameters such as the binary and source directories.
 Then CTest will do what is required to create and run a dashboard.
 This option basically sets up a dashboard and then runs <code class="docutils literal notranslate"><span class="pre">ctest</span> <span class="pre">-D</span></code>
 with the appropriate options.</p>

 <p>This option does the same operations as <code class="docutils literal notranslate"><span class="pre">-S</span></code> but it will do them in a
 separate process.  This is primarily useful in cases where the
 script may modify the environment and you do not want the modified

 <p>This option causes CTest to run tests starting at number <code class="docutils literal notranslate"><span class="pre">Start</span></code>,
 ending at number <code class="docutils literal notranslate"><span class="pre">End</span></code>, and incrementing by <code class="docutils literal notranslate"><span class="pre">Stride</span></code>.  Any additional

 <span id="id1"></span><h2><a class="toc-backref" href="#id18">Label Matching</a><a class="headerlink" href="#label-matching" title="Permalink to this headline">¶</a></h2>
 <p>Tests may have labels attached to them. Tests may be included
 or excluded from a test run by filtering on the labels.
 Each individual filter is a regular expression applied to
 the labels attached to a test.</p>
 <p>When <code class="docutils literal notranslate"><span class="pre">-L</span></code> is used, in order for a test to be included in a
 test run, each regular expression must match at least one
 label.  Using more than one <code class="docutils literal notranslate"><span class="pre">-L</span></code> option means &quot;match <strong>all</strong>
 of these&quot;.</p>
 <p>The <code class="docutils literal notranslate"><span class="pre">-LE</span></code> option works just like <code class="docutils literal notranslate"><span class="pre">-L</span></code>, but excludes tests
 rather than including them. A test is excluded if each regular
 expression matches at least one label.</p>
 <p>If a test has no labels attached to it, then <code class="docutils literal notranslate"><span class="pre">-L</span></code> will never
 include that test, and <code class="docutils literal notranslate"><span class="pre">-LE</span></code> will never exclude that test.
 As an example of tests with labels, consider five tests,
 with the following labels:</p>
 <ul class="simple">
 <li><p><em>test1</em> has labels <em>tuesday</em> and <em>production</em></p></li>
 <li><p><em>test2</em> has labels <em>tuesday</em> and <em>test</em></p></li>
 <li><p><em>test3</em> has labels <em>wednesday</em> and <em>production</em></p></li>
 <li><p><em>test4</em> has label <em>wednesday</em></p></li>
 <li><p><em>test5</em> has labels <em>friday</em> and <em>test</em></p></li>
 </ul>
 <p>Running <code class="docutils literal notranslate"><span class="pre">ctest</span></code> with <code class="docutils literal notranslate"><span class="pre">-L</span> <span class="pre">tuesday</span> <span class="pre">-L</span> <span class="pre">test</span></code> will select <em>test2</em>, which has
 both labels. Running CTest with <code class="docutils literal notranslate"><span class="pre">-L</span> <span class="pre">test</span></code> will select <em>test2</em> and
 <em>test5</em>, because both of them have a label that matches that regular
 expression.</p>
 <p>Because the matching works with regular expressions, take note that
 running CTest with <code class="docutils literal notranslate"><span class="pre">-L</span> <span class="pre">es</span></code> will match all five tests.
 To select the <em>tuesday</em> and <em>wednesday</em> tests together, use a single
 regular expression that matches either of them, like <code class="docutils literal notranslate"><span class="pre">-L</span> <span class="pre">&quot;tue|wed&quot;</span></code>.</p>

 <p>CTest prints timing summary information for each <code class="docutils literal notranslate"><span class="pre">LABEL</span></code> and subproject
 associated with the tests run. The label time summary will not include labels
 that are mapped to subprojects.</p>
 <div class="versionadded">
 <p><span class="versionmodified added">New in version 3.22: </span>Labels added dynamically during test execution are also reported in the
 timing summary.  See <a class="reference internal" href="../command/ctest_test.html#additional-labels"><span class="std std-ref">Additional Labels</span></a>.</p>
 </div>
 <p>When the <span class="target" id="index-1-prop_test:PROCESSORS"></span><a class="reference internal" href="../prop_test/PROCESSORS.html#prop_test:PROCESSORS" title="PROCESSORS"><code class="xref cmake cmake-prop_test docutils literal notranslate"><span class="pre">PROCESSORS</span></code></a> test property is set, CTest will display a
 weighted test timing result in label and subproject summaries. The time is
 reported with <cite>sec*proc</cite> instead of just <cite>sec</cite>.</p>
 <p>The weighted time summary reported for each label or subproject <code class="docutils literal notranslate"><span class="pre">j</span></code>
 is computed as:</p>
 <div class="highlight-none notranslate"><div class="highlight"><pre><span></span>Weighted Time Summary for Label/Subproject j =
     sum(raw_test_time[j,i] * num_processors[j,i], i=1...num_tests[j])

 for labels/subprojects j=1...total
 </pre></div>
 </div>
 <p>where:</p>
 <ul class="simple">
 <li><p><code class="docutils literal notranslate"><span class="pre">raw_test_time[j,i]</span></code>: Wall-clock time for the <code class="docutils literal notranslate"><span class="pre">i</span></code> test
 for the <code class="docutils literal notranslate"><span class="pre">j</span></code> label or subproject</p></li>
 <li><p><code class="docutils literal notranslate"><span class="pre">num_processors[j,i]</span></code>: Value of the CTest <span class="target" id="index-2-prop_test:PROCESSORS"></span><a class="reference internal" href="../prop_test/PROCESSORS.html#prop_test:PROCESSORS" title="PROCESSORS"><code class="xref cmake cmake-prop_test docutils literal notranslate"><span class="pre">PROCESSORS</span></code></a> property
 for the <code class="docutils literal notranslate"><span class="pre">i</span></code> test for the <code class="docutils literal notranslate"><span class="pre">j</span></code> label or subproject</p></li>
 <li><p><code class="docutils literal notranslate"><span class="pre">num_tests[j]</span></code>: Number of tests associated with the <code class="docutils literal notranslate"><span class="pre">j</span></code> label or subproject</p></li>
 <li><p><code class="docutils literal notranslate"><span class="pre">total</span></code>: Total number of labels or subprojects that have at least one test run</p></li>
 </ul>
 <p>Therefore, the weighted time summary for each label or subproject represents
 the amount of time that CTest gave to run the tests for each label or
 subproject and gives a good representation of the total expense of the tests
 for each label or subproject when compared to other labels or subprojects.</p>
 <p>For example, if <code class="docutils literal notranslate"><span class="pre">SubprojectA</span></code> showed <code class="docutils literal notranslate"><span class="pre">100</span> <span class="pre">sec*proc</span></code> and <code class="docutils literal notranslate"><span class="pre">SubprojectB</span></code> showed
 <code class="docutils literal notranslate"><span class="pre">10</span> <span class="pre">sec*proc</span></code>, then CTest allocated approximately 10 times the CPU/core time
 to run the tests for <code class="docutils literal notranslate"><span class="pre">SubprojectA</span></code> than for <code class="docutils literal notranslate"><span class="pre">SubprojectB</span></code> (e.g. so if effort
 is going to be expended to reduce the cost of the test suite for the whole
 project, then reducing the cost of the test suite for <code class="docutils literal notranslate"><span class="pre">SubprojectA</span></code> would
 likely have a larger impact than effort to reduce the cost of the test suite
 for <code class="docutils literal notranslate"><span class="pre">SubprojectB</span></code>).</p>

 <span id="ctest-resource-allocation"></span><h2><a class="toc-backref" href="#id36">Resource Allocation</a><a class="headerlink" href="#resource-allocation" title="Permalink to this headline">¶</a></h2>
 <p>CTest provides a mechanism for tests to specify the resources that they need
 in a fine-grained way, and for users to specify the resources available on
 the running machine. This allows CTest to internally keep track of which
 resources are in use and which are free, scheduling tests in a way that
 prevents them from trying to claim resources that are not available.</p>
 <p>When the resource allocation feature is used, CTest will not oversubscribe
 resources. For example, if a resource has 8 slots, CTest will not run tests
 that collectively use more than 8 slots at a time. This has the effect of
 limiting how many tests can run at any given time, even if a high <code class="docutils literal notranslate"><span class="pre">-j</span></code>
 argument is used, if those tests all use some slots from the same resource.
 In addition, it means that a single test that uses more of a resource than is
 available on a machine will not run at all (and will be reported as
 <code class="docutils literal notranslate"><span class="pre">Not</span> <span class="pre">Run</span></code>).</p>
 <p>A common use case for this feature is for tests that require the use of a GPU.
 Multiple tests can simultaneously allocate memory from a GPU, but if too many
 tests try to do this at once, some of them will fail to allocate, resulting in
 a failed test, even though the test would have succeeded if it had the memory
 it needed. By using the resource allocation feature, each test can specify how
 much memory it requires from a GPU, allowing CTest to schedule tests in a way
 that running several of these tests at once does not exhaust the GPU's memory
 pool.</p>
 <p>Please note that CTest has no concept of what a GPU is or how much memory it
 has, nor does it have any way of communicating with a GPU to retrieve this
 information or perform any memory management. CTest simply keeps track of a
 list of abstract resource types, each of which has a certain number of slots
 available for tests to use. Each test specifies the number of slots that it
 requires from a certain resource, and CTest then schedules them in a way that
 prevents the total number of slots in use from exceeding the listed capacity.
 When a test is executed, and slots from a resource are allocated to that test,
 tests may assume that they have exclusive use of those slots for the duration
 of the test's process.</p>
 <p>The CTest resource allocation feature consists of two inputs:</p>
 <ul class="simple">
 <li><p>The <a class="reference internal" href="#ctest-resource-specification-file"><span class="std std-ref">resource specification file</span></a>,
 described below, which describes the resources available on the system.</p></li>
 <li><p>The <span class="target" id="index-0-prop_test:RESOURCE_GROUPS"></span><a class="reference internal" href="../prop_test/RESOURCE_GROUPS.html#prop_test:RESOURCE_GROUPS" title="RESOURCE_GROUPS"><code class="xref cmake cmake-prop_test docutils literal notranslate"><span class="pre">RESOURCE_GROUPS</span></code></a> property of tests, which describes the
 resources required by the test.</p></li>
 </ul>
 <p>When CTest runs a test, the resources allocated to that test are passed in the
 form of a set of
 <a class="reference internal" href="#ctest-resource-environment-variables"><span class="std std-ref">environment variables</span></a> as
 described below. Using this information to decide which resource to connect to
 is left to the test writer.</p>
 <p>The <code class="docutils literal notranslate"><span class="pre">RESOURCE_GROUPS</span></code> property tells CTest what resources a test expects
 to use grouped in a way meaningful to the test.  The test itself must read
 the <a class="reference internal" href="#ctest-resource-environment-variables"><span class="std std-ref">environment variables</span></a> to
 determine which resources have been allocated to each group.  For example,
 each group may correspond to a process the test will spawn when executed.</p>
 <p>Note that even if a test specifies a <code class="docutils literal notranslate"><span class="pre">RESOURCE_GROUPS</span></code> property, it is still
 possible for that to test to run without any resource allocation (and without
 the corresponding
 <a class="reference internal" href="#ctest-resource-environment-variables"><span class="std std-ref">environment variables</span></a>)
 if the user does not pass a resource specification file. Passing this file,
 either through the <code class="docutils literal notranslate"><span class="pre">--resource-spec-file</span></code> command-line argument or the
 <code class="docutils literal notranslate"><span class="pre">RESOURCE_SPEC_FILE</span></code> argument to <span class="target" id="index-2-command:ctest_test"></span><a class="reference internal" href="../command/ctest_test.html#command:ctest_test" title="ctest_test"><code class="xref cmake cmake-command docutils literal notranslate"><span class="pre">ctest_test()</span></code></a>, is what activates the
 resource allocation feature. Tests should check the
 <code class="docutils literal notranslate"><span class="pre">CTEST_RESOURCE_GROUP_COUNT</span></code> 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 <code class="docutils literal notranslate"><span class="pre">CTEST_RESOURCE_GROUP_COUNT</span></code> variable will not exist,
 even if it exists for the parent <code class="docutils literal notranslate"><span class="pre">ctest</span></code> process. If a test absolutely must
 have resource allocation, then it can return a failing exit code or use the

 <p>Each array element is a JSON object with members whose names are equal to the
 desired resource types, such as <code class="docutils literal notranslate"><span class="pre">gpus</span></code>. These names must start with a
 lowercase letter or an underscore, and subsequent characters can be a
 lowercase letter, a digit, or an underscore. Uppercase letters are not
 allowed, because certain platforms have case-insensitive environment
 variables. See the <a class="reference internal" href="#environment-variables">Environment Variables</a> section below for
 more information. It is recommended that the resource type name be the plural
 of a noun, such as <code class="docutils literal notranslate"><span class="pre">gpus</span></code> or <code class="docutils literal notranslate"><span class="pre">crypto_chips</span></code> (and not <code class="docutils literal notranslate"><span class="pre">gpu</span></code> or

 <p>Please note that the names <code class="docutils literal notranslate"><span class="pre">gpus</span></code> and <code class="docutils literal notranslate"><span class="pre">crypto_chips</span></code> are just examples,
 and CTest does not interpret them in any way. You are free to make up any
 resource type you want to meet your own requirements.</p>
 <p>The value for each resource type is a JSON array consisting of JSON objects,

 the identifier can be a lowercase letter, a digit, or an underscore.
 Uppercase letters are not allowed.</p>
 <p>Identifiers must be unique within a resource type. However, they do not
 have to be unique across resource types. For example, it is valid to have a
 <code class="docutils literal notranslate"><span class="pre">gpus</span></code> resource named <code class="docutils literal notranslate"><span class="pre">0</span></code> and a <code class="docutils literal notranslate"><span class="pre">crypto_chips</span></code> resource named <code class="docutils literal notranslate"><span class="pre">0</span></code>,
