<p style="font-family: arial; background-color: rgb(255, 255, 255);" class="">Dear all,</p>

</p>
<p style="font-family: arial; background-color: rgb(255, 255, 255);" class="">A technology preview for the forthcoming McStas 3.x series is now available for testing!</p>
<p style="font-family: arial; background-color: rgb(255, 255, 255);" class="">Main highlights of the release are:</p>
<ul style="font-family: arial; background-color: rgb(255, 255, 255);" class="">
<li class="">New code-generation scheme based on functions instead of #defines</li><li class="">Much improved compilation-times, the code is better suited for modern compilers</li><li class="">In most cases a speed-up of order 20% on CPU</li><li class="">Limited, experimental support for OpenACC acceleration on NVIDIA GPU's</li><li class="">Speedups measured using top-notch NVIDIA V100 datacenter cards are in the range of 10-600 with respect to a single-core CPU</li><li class="">In essence, you will need a Linux machine with an NVIDIA card and the PGI compiler to make use of the GPU-support</li></ul>
<p style="font-family: arial; background-color: rgb(255, 255, 255);" class="">For more details and instructions, please refer to <a href="https://github.com/McStasMcXtrace/McCode/wiki/McStas-3.0beta-technology-preview-release-notes" class="">this document on

<p style="font-family: arial; background-color: rgb(255, 255, 255);" class="">Thanks to:</p>
