<h1>Updates in 2021.3<a class="headerlink" href="#updates-in-2021-3" title="Permalink to this headline"></a></h1>
<p><strong>General</strong></p>
<ul class="simple">
<li><p>Added support for the CUDA toolkit 11.5.</p></li>
<li><p>Added a new rule for detecting inefficient memory access patterns in the L1TEX cache and L2 cache.</p></li>
<li><p>Added a new rule for detecting high usage of system or peer memory.</p></li>
<li><p>Added new <code class="docutils literal notranslate"><span class="pre">IAction::sass_by_pc</span></code> function to the the <a class="reference external" href="../NvRulesAPI/index.html#abstract">NvRules API</a>.</p></li>
<li><p>The <a class="reference external" href="../CustomizationGuide/index.html#python-report-interface">Python-based report interface</a> is now available for Windows and MacOS hosts, too.</p></li>
<li><p>Added Hierarchical Roofline section files in a new “roofline” section set.</p></li>
<li><p>Added support for collecting CPU call stack information.</p></li>
</ul>
<p><strong>NVIDIA Nsight Compute</strong></p>
<ul class="simple">
<li><p>Added support for new remote profiling <a class="reference external" href="../NsightCompute/index.html#remote-connections">SSH connection and authentication options</a> as well as local SSH configuration files.</p></li>
<li><p>Added an <a class="reference external" href="../NsightCompute/index.html#occupancy-calculator">Occupancy Calculator</a> which can be opened directly from a profile report or as a new activity. It offers feature parity to the CUDA Occupancy Calculator <a class="reference external" href="http://docs.nvidia.com/cuda/cuda-occupancy-calculator/index.html">spreadsheet</a>.</p></li>
<li><p>Added new <a class="reference external" href="../NsightCompute/index.html#tool-window-baselines">Baselines tool window</a> to manage (hide, update, re-order, save/load) baseline selections.</p></li>
<li><p>The Source page views now support multi-line/cell selection and copy/paste. Different colors are used for highlighting selections and correlated lines.</p></li>
<li><p>The search edit on the Source page now supports <em>Shift+Enter</em> to search in reverse direction.</p></li>
<li><p>The <a class="reference external" href="../ProfilingGuide/index.html#memory-chart">Memory Workload Analysis Chart</a> can be configured to show throughput values instead of transferred bytes.</p></li>
<li><p>The <em>Profile</em> activity now supports the <code class="docutils literal notranslate"><span class="pre">--devices</span></code> option.</p></li>
<li><p>The <em>NVLink Topology</em> diagram displays per NVLink metrics.</p></li>
<li><p>Added a new tool window showing the CPU call stack at the location where the current thread was suspended during interactive profiling activities.</p></li>
<li><p>If enabled, the <em>Call Stack / NVTX</em> page of the profile report shows the captured CPU call stack for the selected kernel launch.</p></li>
</ul>
<p><strong>NVIDIA Nsight Compute CLI</strong></p>
<ul class="simple">
<li><p>Added support for printing source/metric content with the new <code class="docutils literal notranslate"><span class="pre">--page</span> <span class="pre">source</span></code> and <code class="docutils literal notranslate"><span class="pre">--print-source</span></code><a class="reference external" href="../NsightComputeCli/index.html#command-line-options-console-output">command line options</a>.</p></li>
<li><p>Added new option <code class="docutils literal notranslate"><span class="pre">--call-stack</span></code> to enable collecting the CPU call stack for every profiled kernel launch.</p></li>
</ul>
<p><strong>Resolved Issues</strong></p>
<ul class="simple">
<li><p>Fixed that <code class="docutils literal notranslate"><span class="pre">memory_*</span></code> metrics could not be collected with the <code class="docutils literal notranslate"><span class="pre">--metrics</span></code> option.</p></li>
<li><p>Fixed that selection and copy/paste was not supported for section header tables on the Details page.</p></li>
<li><p>Fixed issues with the Source page when collapsing the content.</p></li>
<li><p>Fixed that the UI could crash when applying rules to a new profile result.</p></li>
<li><p>Fixed that PC Sampling metrics were not available for <em>Profile Series</em>.</p></li>
<li><p>Fixed that local profiling did not work if no non-loopback address was configured for the system.</p></li>
<li><p>Fixed termination of remote-launched applications. On QNX, terminating an application profiled via <em>Remote Launch</em> is now supported. Canceling remote-launched <em>Profile</em> activities is now supported.</p></li>
