Biweekly meeting: C++ Modules in ROOT

Wednesday 16 Sept 2020, 14:00 → 15:00 Europe/Zurich

Oksana Shadura (University of Nebraska Lincoln (US)), Vasil Georgiev Vasilev (Institute for Advanced Physical Studies (BG))

Attendance: David, Vassil

Vassil: Upgrading llvm.

David: Got rid of the compilation warnings in cmssw. Doing performance checks. I am working on reducing the number of test failures. We have 1 more failing relval check than the regular IB and a few unit test failures.

Priorities: Fix boost_fusion. Understand performance. Reduce module duplicates.

Enabled modules in cmssw: 285/395 (external modules such as boost excluded).
Enabled external modules in cmssw: boost 85, clhep 1, tinyxml2 1, cuda 1.

CXXMODULE IB stats: 8 failing relvals; 13 failing unit tests.

AOB: Next meeting in two weeks
