<h1>Updates in 2022.1<a class="headerlink" href="#updates-in-2022-1" title="Permalink to this headline"></a></h1>
<p><strong>General</strong></p>
<ul class="simple">
<li><p>Added support for the CUDA toolkit 11.6.</p></li>
</ul>
<ul class="simple">
<li><p>Added support for GA103 chips.</p></li>
</ul>
<ul class="simple">
<li><p>Added a new <a class="reference external" href="../ProfilingGuide/index.html#range-replay">Range Replay</a> mode to profile ranges of multiple, concurrent kernels. Range replay is available in the NVIDIA Nsight Compute CLI and the non-interactive Profile activity.</p></li>
<li><p>Added a new rule to detect non-fused floating-point instructions.</p></li>
<li><p>The Uncoalesced Memory access rules now show results in a dynamic table.</p></li>
<li><p>Unix Domain Sockets and Windows Named Pipes are used for local connection between the host and target processes on x86_64 Linux and Windows, respectively.</p></li>
<li><p>The <a class="reference external" href="../NvRulesAPI/index.html#abstract">NvRules API</a> now supports querying action names using different function name bases (e.g. demangled).</p></li>
</ul>
<p><strong>NVIDIA Nsight Compute</strong></p>
<ul class="simple">
<li><p>The default <a class="reference external" href="../NsightCompute/index.html#profiler-report-pages">report page</a> is now chosen automatically when opening a report.</p></li>
<li><p>Added coverage for ECC (Error Correction Code) operations in the L2 Cache table of the Memory Analysis section.</p></li>
<li><p>Added a new <a class="reference external" href="../ProfilingGuide/topics/memory-tables-l2-evict-policy.html">L2 Evict Policies</a> table to the Memory Analysis section.</p></li>
<li><p>The <a class="reference external" href="../NsightCompute/index.html#occupancy-calculator">Occupancy Calculator</a> now updates automatically when the input changes.</p></li>
<li><p>Added new metric <em>Thread Instructions Executed</em> to the Source page.</p></li>
<li><p>Added tooltips to the <a class="reference external" href="../NsightCompute/index.html#profiler-report-source-page">Register Dependency</a> columns in the Source page to identify the associated register more conveniently.</p></li>
<li><p>Improved the selection of Sections and Sets in the Profile activity connection dialog.</p></li>
<li><p>NVLink utilization is shown in the NVLink Tables section.</p></li>
<li><p>NVLink links are colored according to the measured throughput.</p></li>
</ul>
<p><strong>NVIDIA Nsight Compute CLI</strong></p>
<ul class="simple">
<li><p><code class="docutils literal notranslate"><span class="pre">--kernel-regex</span></code> and <code class="docutils literal notranslate"><span class="pre">--kernel-regex-base</span></code> options are no longer supported. Alternate options are <code class="docutils literal notranslate"><span class="pre">--kernel-name</span></code> and <code class="docutils literal notranslate"><span class="pre">--kernel-name-base</span></code> respectively, added in 2021.1.0.</p></li>
<li><p>Added support to resolve CUDA source files in the <code class="docutils literal notranslate"><span class="pre">--page</span> <span class="pre">source</span></code> output with the new <code class="docutils literal notranslate"><span class="pre">--resolve-source-file</span></code><a class="reference external" href="../NsightComputeCli/index.html#command-line-options-console-output">command line option</a>.</p></li>
<li><p>Added new option <code class="docutils literal notranslate"><span class="pre">--target-processes-filter</span></code> to filter the processes being profiled by name.</p></li>
<li><p>The CPU Stack Trace is shown in the NVIDIA Nsight Compute CLI output.</p></li>
</ul>
<p><strong>Resolved Issues</strong></p>
<ul class="simple">
<li><p>Fixed the calculation of aggregated average instruction execution metrics in non-SASS views on the Source page.</p></li>
<li><p>Fixed that atomic instructions are counted as both loads and stores in the Memory Analysis tables.</p></li>
</ul>
