<ul class="simple">
<li><p>Added support for the NVIDIA Ampere GPUs with compute capability 8.6 and CUDA toolkit 11.1.</p></li>
<li><p>Added support for application replay to collect metric results across multiple application runs, instead of replaying individual kernels.</p></li>
<li><p>Added new <code class="docutils literal notranslate"><span class="pre">launch__device_id</span></code> metric.</p></li>
<li><p>Added support for NVLink (<code class="docutils literal notranslate"><span class="pre">nvl*</span></code>) metrics for GPUs with compute capabilities 7.0, 7.5 and 8.0</p></li>
<li><p>Added documentation for memory charts and tables in the <a class="reference external" href="../ProfilingGuide/index.html#memory-chart">Profiling Guide</a>.</p></li>
</ul>
<p><strong>NVIDIA Nsight Compute</strong></p>
<ul class="simple">
<li><p>Updated menu and toolbar layout.</p></li>
<li><p>Added support for zoom and pan on roofline charts.</p></li>
<li><p>The <em>Resources</em> tool window shows the current CUDA stream attributes.</p></li>
<li><p>The memory chart shows a heatmap for link and port utilization.</p></li>
<li><p>The hot-spot tables in the <em>Source Counters</em> section now show values as percentages, too.</p></li>
<li><p>On-demand resolve of remote CUDA-C source is now available for MacOS hosts.</p></li>
<li><p>Metric columns in the <em>Summary</em> and <em>Raw</em> pages are now sortable.</p></li>
<li><p>Added a new option to set the number of recent API calls shown in the <em>API Stream</em> tool window.</p></li>
</ul>
<p><strong>NVIDIA Nsight Compute CLI</strong></p>
<ul class="simple">
<li><p>CLI output now shows NVTX payload information.</p></li>
<li><p>CSV output now shows NVTX states.</p></li>
<li><p>Added a new <code class="docutils literal notranslate"><span class="pre">--replay-mode</span></code> option to select the mechanism used for replaying a kernel launch multiple times.</p></li>
<li><p>Added a new <code class="docutils literal notranslate"><span class="pre">--kill</span></code> option to terminate the application once all requested kernels were profiled.</p></li>
<li><p>Added a new <code class="docutils literal notranslate"><span class="pre">--log-file</span></code> option to decide the output stream for printing tool output.</p></li>
<li><p>Added a new <code class="docutils literal notranslate"><span class="pre">--check-exit-code</span></code> option to decide if the child application exit code should be checked.</p></li>
</ul>
<p><strong>Resolved Issues</strong></p>
<ul class="simple">
<li><p>The profiling progress dialog is not dismissed automatically anymore after an error.</p></li>
<li><p>The inter-process lock is now automatically given write permissions for all users.</p></li>
<li><p>All project extensions are enabled in the default dialog filter.</p></li>
<li><p>Fixed handling of targets using <em>tcsh</em> during remote profiling.</p></li>
<li><p>Fixed handling of quoted application arguments on Windows.</p></li>
