Dear all,
<div class=""><br class="">
</div>
<div class=""><br class="">
</div>
<div class="">The McXtrace team is happy to announce that our McXtrace 3.0 “next generation” release is now available.</div>
<div class=""><br class="">
</div>
<div class="">
<div class="">McXtrace 3.0 is the first release in the 3.0 series with a completely rewritten code-generator and thereby</div>
<div class="">support for GPU-acceleration through the OpenACC programming model. </div>
<div class=""><br class="">
</div>
<div class="">We have seen speedups of 1-2 orders of magnitude over the CPU version, depending on the computational</div>
<div class="">Problem / complexity.</div>
<div class=""><br class="">
</div>
<div class="">THANKS:</div>
<div class="">- Thanks to: all members of the team (and also to the McStas team), for pulling together to make this possible.</div>
<div class="">- Thanks to the mentors at the GPU Hackathons that really made this happen</div>
<div class="">- Thanks to NVIDIA for making the hackathons happen</div>
<div class=""><br class="">
</div>
<div class="">INSTALLATION:</div>
<div class="">- Installation instructions for McXtrace-3.0 and support libraries may be found on our the McCode github-site:</div>
<div class=""><a href="https://github.com/McStasMcXtrace/McCode/tree/master/Install_McXtrace-3.x" class="">https://github.com/McStasMcXtrace/McCode/tree/master/Install_McXtrace-3.x</a></div>
<div class="">- OpenACC acceleration is at present available out of the box on Linux. </div>
<div class="">- On windows it is possible to target GPU-acceleration through Windows Subsystem For Linux v2: WSL2. </div>
<div class="">- The present McXtrace-3.0 implementation relies the concept managed memory, which</div>
<div class=""> is at the time of writing only supported by the Linux version of the NVHPC-kit</div>
<div class=""> (downloadable from <a href="https://developer.nvidia.com/hpc-sdk" class="">https://developer.nvidia.com/hpc-sdk</a>)</div>
<div class=""><br class="">
</div>
<div class="">For more information on the GPU-features of the release, please consult the CHANGES_McXtrace document on GitHub</div>
<div class="">(<a href="https://github.com/McStasMcXtrace/McCode/blob/mcxtrace-3.0-release/CHANGES_McXtrace" class="">https://github.com/McStasMcXtrace/McCode/blob/mcxtrace-3.0-release/CHANGES_McXtrace</a>) and the section </div>
<div class="">“Migrating from McStas 2.x to 3.x (and McXtrace 1.x to 3.x)” in our
<a href="https://github.com/McStasMcXtrace/McCode/wiki" class="">https://github.com/McStasMcXtrace/McCode/wiki</a> </div>
<div class=""><br class="">
</div>
<div class="">Tools:</div>
<div class=""> - The perl-suite of tools are no longer actively supported. They may still work.</div>
<div class=""><br class="">
</div>
<div class="">Platforms:</div>
<div class=""> - We support the platforms Debian/Ubuntu and Fedora for Linux, 64 bit Windows 10, and recent 64 bit macOS (big Sur and</div>
<div class=""> newer). For FreeBSD you may build from source, an entry into the ports system is pending.</div>
<div class=""><br class="">
</div>
<div class="">Components and Instruments:</div>
<div class=""> - Most components and instruments work out of the box. See <a href="https://new-nightly.mcxtrace.org/" class="">
https://new-nightly.mcxtrace.org</a> for details.</div>
<div class=""> - Monitor_nD.comp: the uservar utility should now be given a string insted of a token name to measure a USERVAR entity</div>
<div class=""> tagged onto the photon. The string is used to look-up the name of the variable which should be declared in the USERVARS-section</div>
<div class=""> of the instrument file.</div>
