@fwyzard , this looks good to go. Do you have any other changesing mind? One simplification we can do is to set cppstd in cuda-flags.file and then use it where needed e.g in cuda-toolfile.spec, cupla.spec and cuda-flags.file

[fwyzard]

Do you mean having a way to synchronise the -std=c++## flags in

• cmsdist/cuda-flags.file

  Line 20 in 260596a

  %define cuda_flags_0 -std=c++17 -O3

• cmsdist/cuda-toolfile.spec

  Line 42 in 260596a

  <flags CUDA_HOST_CXXFLAGS="-std=c++17"/>

• cmsdist/cupla.spec

  Line 21 in 260596a

  HOST_FLAGS="-std=c++17 -O2 -pthread -fPIC -Wall -Wextra"

?
Yes, that sounds like a good idea.

Should I do it here, or open a separate PR for it ?

We should also update the cub toolkit, now that it comes as a part of the cuda package.

[smuzaffar]

yes that is the idea, so that in future we only update host std flag in one place.
Yes please, update it here, I will rerun a final test for production architecture ( just to get the labels green).

This pull request is fully signed and it will be integrated in one of the next IB/CMSSW_11_2_X/master IBs (tests are also fine). This pull request will now be reviewed by the release team before it's merged. @silviodonato, @dpiparo (and backports should be raised in the release meeting by the corresponding L2)
