<h1>Updates in 2021.2<a class="headerlink" href="#updates-in-2021-2" title="Permalink to this headline"></a></h1>
<p><strong>General</strong></p>
<ul class="simple">
<li><p>Added support for the CUDA toolkit 11.4.</p></li>
<li><p>Added support for OptiX version 7.3.</p></li>
<li><p>Added support for profiling on <a class="reference external" href="https://www.nvidia.com/en-us/data-center/virtual-gpu-technology/">NVIDIA virtual GPUs</a> (vGPUs) on an upcoming GRID/vGPU release.</p></li>
<li><p>Added a new <a class="reference external" href="../CustomizationGuide/index.html#python-report-interface">Python-based report interface</a> for interacting with report files from Python scripts.</p></li>
<li><p>Added a new rule to warn users when sampling metrics were selected, but no sampling data was collected.</p></li>
<li><p>Renamed <em>SOL</em> to <em>Throughput</em> in the Speed of Light section.</p></li>
<li><p>Renamed several <code class="docutils literal notranslate"><span class="pre">memory_*</span></code> metrics used on the <em>Source</em> page, to better reflect the measured value. See the <a class="reference external" href="../NsightCompute/index.html#profiler-report-source-page">Source page</a> documentation for more details.</p></li>
</ul>
<p><strong>NVIDIA Nsight Compute</strong></p>
<ul class="simple">
<li><p>Added support for opening <a class="reference external" href="https://docs.nvidia.com/cuda/cuda-binary-utilities/index.html#cuda-binary">cubin files</a> in a <a class="reference external" href="../NsightCompute/index.html#cubin-viewer">Standalone Source Viewer</a> without profiling the application.</p></li>
<li><p>Moved the output of all rules so that it is visible even if a section’s body is collapsed. Visibility of the rules’ output can be toggled by a new button in the report header.</p></li>
<li><p>The profiler report header now shows the report name for each baseline when ambiguous.</p></li>
<li><p>Rules can define <em>Focused Metrics</em> that were most important for triggering their result output. Metrics are provided per result message which additional information, such as the underlying conditions and thresholds.</p></li>
<li><p><a class="reference external" href="../ProfilingGuide/index.html#memory-tables">Memory tables</a> show tooltips for cells with derived metric calculations.</p></li>
<li><p>Added a knowledge base service to show more comprehensive background information on metric names and descriptions in their tooltips.</p></li>
<li><p>Following a link in the Source Counters hot spot tables automatically selects the corresponding metric in the Source page.</p></li>
<li><p>Added new columns for visualizing register dependencies in the SASS view of the <a class="reference external" href="../NsightCompute/index.html#profiler-report-source-page">Source page</a>.</p></li>
<li><p>Functions in the SASS view are now sorted by name.</p></li>
<li><p>Added support for OptiX 7.x resource tracking in the interactive profile activity. The <em>Resources</em> tool window will show information on instantiated <code class="docutils literal notranslate"><span class="pre">optixDeviceContexts,</span> <span class="pre">optixModules,</span> <span class="pre">optixProgramGroups,</span> <span class="pre">optixPipelines</span> <span class="pre">and</span> <span class="pre">optixDenoiser</span></code> objects.</p></li>
<li><p>Added support for new CUDA graph memory allocation APIs.</p></li>
<li><p>Improved consistency between command line parameters and the <em>Next Trigger</em> filter in the API Stream window for handling of regex inputs. The <em>Next Trigger</em> filter now considers kernel/API name as a regular expression only if string has <code class="docutils literal notranslate"><span class="pre">regex:</span></code> as prefix.</p></li>
<li><p>Added ability to select font settings in the options dialog.</p></li>
<li><p>Added ability to configure the metrics shown on the summary page via the options dialog.</p></li>
<li><p>The selected heatmap color scale now also applies to the <em>Memory chart</em>.</p></li>
<li><p>The ncu-ui script now checks for missing library dependencies, such as OpenGL or <a class="reference external" href="https://doc.qt.io/qt-5/linux-requirements.html">Qt</a>.</p></li>
</ul>
<p><strong>NVIDIA Nsight Compute CLI</strong></p>
<ul class="simple">
<li><p>Added environment variable <a class="reference external" href="../NsightComputeCli/index.html#environment-variables">NV_COMPUTE_PROFILER_DISABLE_STOCK_FILE_DEPLOYMENT=1</a> to skip deployment of section and rule files.</p></li>
</ul>
<p><strong>Resolved Issues</strong></p>
<ul class="simple">
<li><p>Fixed a performance issue in the NVIDIA Nsight Compute CLI when using <code class="docutils literal notranslate"><span class="pre">--page</span> <span class="pre">raw</span> <span class="pre">--csv</span> <span class="pre">--units</span> <span class="pre">auto</span></code>.</p></li>
<li><p>Fixed that the SSH passphase key is no longer persisted in the project file.</p></li>
<li><p>Fixed state of restore button in connection dialog. The button now supports restoring the default settings, if current setting differ from the default.</p></li>
<li><p>Fixed that the complete GPU name can be shown in the NVLINK topology diagram on MacOS.</p></li>
<li><p>Fixed that collapsing the Source view reset the selected metrics.</p></li>
<li><p>Fixed that correlated lines could differ between filtered and unfiltered views of the executed functions.</p></li>
<li><p>Fixed that two application icons were shown in the MacOS dock.</p></li>
<li><p>Improved HiDPI awareness.</p></li>
