<h1>Updates in 2024.1<a class="headerlink" href="#updates-in-2024-1" title="Permalink to this headline"></a></h1>
<p><strong>General</strong></p>
<ul class="simple">
<li><p>Switched to using OpenSSL version 3.0.10.</p></li>
<li><p>Added new metrics available when profiling on CUDA Green Contexts.</p></li>
<li><p>Reduced the number of passes required for collecting <a class="reference external" href="../ProfilingGuide/index.html#pm-sampling">PM sampling</a> sections.</p></li>
<li><p>Counter domains can now be specified for PM sampling metrics in section files.</p></li>
<li><p>PM sampling metrics can now be queried in the command line and Metric Details window by specifying the respective <code class="docutils literal notranslate"><span class="pre">collection</span></code> option.</p></li>
<li><p>Added a new optional <a class="reference external" href="../ProfilingGuide/index.html#sections-and-rules">PmSampling_WarpStates</a> section for understanding warp stall reasons over the workload duration.</p></li>
<li><p>Added a new rule for detecting load imbalances.</p></li>
<li><p>Improved the performance of graph-level profiling on new drivers.</p></li>
<li><p>Updated the <a class="reference external" href="../ProfilingGuide/index.html#compatibility">metrics compatibility</a> table for OptiX cmdlists and instruction-level SASS metrics.</p></li>
</ul>
<p><strong>NVIDIA Nsight Compute</strong></p>
<ul class="simple">
<li><p>Added SASS view and Source Markers support in <a class="reference external" href="../NsightCompute/index.html#source-comparison">Source Comparison</a>.</p></li>
<li><p>Improved <a class="reference external" href="../NsightCompute/index.html#source-comparison">Source Comparison</a> diff visualization by adding empty lines on other side of inserted/deleted lines.</p></li>
<li><p>The Source page <a class="reference external" href="../NsightCompute/index.html#profiler-report-source-page-metrics">column chooser</a> can now be opened directly from the Navigation drop down.</p></li>
<li><p>Added a <a class="reference external" href="../NsightCompute/index.html#tool-window-launch-details">Launch Details</a> tool window for showing information about individual launches within larger workloads like OptiX command lists.</p></li>
<li><p>Added support for CUDA Green Contexts in the <a class="reference external" href="../NsightCompute/index.html#tool-window-resources">Resources</a> tool window, the Launch Statistics section and the report header.</p></li>
</ul>
<p><strong>NVIDIA Nsight Compute CLI</strong></p>
<ul class="simple">
<li><p>Improved documentation on NVTX expressions and command line output when a potentially incorrect expression led to no workloads being profiled.</p></li>
<li><p>Improved checking for invalid expressions when using the <code class="docutils literal notranslate"><span class="pre">--target-processes-filer</span></code> option.</p></li>
</ul>
<p><strong>Resolved Issues</strong></p>
<ul class="simple">
<li><p>Fixed that the L1 cache achieved roofline value was missing when profiling on GH100.</p></li>
<li><p>Fixed several “Launch Failed” errors when collecting instruction-level SASS metrics.</p></li>
<li><p>Fixed that <a class="reference external" href="../NsightCompute/index.html#profiler-report-source-page-metrics">Live Register</a> values would be too high for some workloads.</p></li>
<li><p>Fixed a scrolling issue on the Source page when collapsing a multi-file view.</p></li>
<li><p>Fixed an issue that no PM sampling data would be shown in the timeline when context switch trace was not available.</p></li>
<li><p>Fixed a display issue in the memory chart when adding baselines.</p></li>
<li><p>Fixed a crash when adding baselines.</p></li>
<li><p>Fixed a crash in timeline views when not all configured data was available.</p></li>
<li><p>Fixed that the application history was not always deleted when selecting Reset Application Data.</p></li>
<li><p>Fixed an error in the metric compatibility documentation.</p></li>
