<h1>Updates in 2023.1<a class="headerlink" href="#updates-in-2023-1" title="Permalink to this headline"></a></h1>
<p><strong>General</strong></p>
<ul class="simple">
<li><p>Added support for the CUDA toolkit 12.1.</p></li>
<li><p>Added a new <a class="reference external" href="../ProfilingGuide/index.html#application-range-replay">app-range</a> replay mode to profile ranges without API capture by relaunching the entire application multiple times.</p></li>
<li><p>Added <em>sharedBankConflicts</em> sample CUDA application and document to show how NVIDIA Nsight Compute can be used to analyze and identify the shared memory bank conflicts which result in inefficient shared memory accesses. Refer to the <code class="docutils literal notranslate"><span class="pre">README.TXT</span></code> file, sample code and document under <code class="docutils literal notranslate"><span class="pre">extras/samples/sharedBankConflicts</span></code>.</p></li>
<li><p>Jupyter notebook samples are available in the Nsight training <a class="reference external" href="https://github.com/NVIDIA/nsight-training/blob/master/cuda/nsight_compute/python_report_interface">github repository</a>.</p></li>
<li><p>The equivalent of the <a class="reference external" href="../CustomizationGuide/index.html#python-report-interface-high-level">high-level Python report interface</a> is now available in rule files.</p></li>
</ul>
<p><strong>NVIDIA Nsight Compute</strong></p>
<ul class="simple">
<li><p>Added support for profiling individual metrics in <a class="reference external" href="../NsightCompute/index.html#connection-activity-interactive">Interactive Profile activity</a>. A new input field for metrics was added in the <a class="reference external" href="../NsightCompute/index.html#tool-window-sections-info">Metric Selection</a> tool window.</p></li>
<li><p>Files on remote systems can be opened directly from the <a class="reference external" href="../NsightCompute/index.html#main-menu">menu</a>.</p></li>
<li><p>Metric- and section-related entries in the menu, <a class="reference external" href="../NsightCompute/index.html#connection-activity-non-interactive">Profile activity</a> and <a class="reference external" href="../NsightCompute/index.html#tool-window-sections-info">Metric Selection</a> tool window were renamed to make them more clear.</p></li>
<li><p>CPU and GPU <a class="reference external" href="../ProfilingGuide/index.html#metrics-reference">NUMA topology metrics</a> can be collected on applicable systems. Topology information is shown in a new <a class="reference external" href="../ProfilingGuide/index.html#sections-and-rules">NUMA Affinity section</a>.</p></li>
<li><p>Added content-aware suggestions to the Details page to provide suggestions based on the selected profiling options.</p></li>
<li><p>Added support for <a class="reference external" href="../NsightCompute/index.html#profiler-report-source-page-navigation">re-resolving source files</a> on the Source page.</p></li>
<li><p>Not-issued warp stall reasons are removed from the Source Counters section tables and hidden by default on the Source page. Users should focus on regular warp stall reasons by default and only inspect not-issued samples if this distinction is needed.</p></li>
<li><p>Added support to search missing CUDA source files to permanently import into the report using <a class="reference external" href="../NsightCompute/index.html#options-source-lookup">Source Lookup options</a> in the <a class="reference external" href="../NsightCompute/index.html#connection-activity-interactive">Interactive Profile activity</a>.</p></li>
<li><p>The <a class="reference external" href="../NsightCompute/index.html#profiler-report-source-page-metrics">source page</a> now shows metric values as percentages by default. New buttons are added to support switching between different value modes.</p></li>
</ul>
<p><strong>NVIDIA Nsight Compute CLI</strong></p>
<ul class="simple">
<li><p>Added support for config files in the current working or user directory to set default ncu parameters. See the <a class="reference external" href="../NsightComputeCli/index.html#command-line-options-general">General options</a> for more details.</p></li>
<li><p>Added <code class="docutils literal notranslate"><span class="pre">--range-filter</span></code><a class="reference external" href="../NsightComputeCli/index.html#command-line-options-console-output">command line option</a> which allows to select subset of enabled profile ranges.</p></li>
<li><p>Added new <code class="docutils literal notranslate"><span class="pre">--source-folders</span></code><a class="reference external" href="../NsightComputeCli/index.html#command-line-options-profile">command line option</a> that allows to recursively search for missing CUDA source files to permanently import into the report.</p></li>
</ul>
<p><strong>Resolved Issues</strong></p>
<ul class="simple">
<li><p>Fixed performance issues on the Summary and Raw pages for large reports.</p></li>
<li><p>Improved support for non-ASCII characters in filenames.</p></li>
<li><p>Fixed an issue with delayed updates of assembly analysis information on the Source page’s Source and PTX views.</p></li>
<li><p>Fixed potential crashes when using the Python report interface.</p></li>
