[Neutron] McStas 3.0beta technology preview available!

[Peter Kjær Willendrup]

Dear all,


A technology preview for the forthcoming McStas 3.x series is now available for testing!

Main highlights of the release are:

  *   New code-generation scheme based on functions instead of #defines
  *   Much improved compilation-times, the code is better suited for modern compilers
  *   In most cases a speed-up of order 20% on CPU
  *   Limited, experimental support for OpenACC acceleration on NVIDIA GPU's
  *   Speedups measured using top-notch NVIDIA V100 datacenter cards are in the range of 10-600 with respect to a single-core CPU
  *   In essence, you will need a Linux machine with an NVIDIA card and the PGI compiler to make use of the GPU-support

For more details and instructions, please refer to this document on our Wiki<https://github.com/McStasMcXtrace/McCode/wiki/McStas-3.0beta-technology-preview-release-notes>

Thanks to:

  *   Thanks to all members of the joint McStas-McXtrace team<https://github.com/McStasMcXtrace/McCode/wiki/McStas-McXtrace-team>, you guys ROCK!
  *   Thanks to Guido Juckeland (HZDR,DE) and Sebastian Alfthan (CSC,FI) who were behind the GPU Hackathons we participated in
  *   Thanks to our NVIDIA mentors Vishal Metha, Christian Hundt and Alexey Romanenko


Regards on behalf of the McStas-McXtrace developers,

Peter Willendrup
