Lin log chi2 cut for patatrack #34419

VinInn · 2021-07-09T08:13:44Z

Modify the parameterization of the chi2cut to a simple linlog.
Chi2 cut "optimized" for PU ~50 using current realistic conditions for pixel detector.

Took the opportunity the address the issues raised in #34400

code changes are in line with the PR description
- items from follow up to PR review of CPEFast to better reproduce Generic #34286 #34400 are mostly/partially addressed
jenkins tests pass and comparisons with the baseline show small differences in the pixel tracking GPU workflow

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

out of curiosity: how does the performance of roughLog compare with CUDA native ::logf ?

fwyzard · 2021-07-16T08:16:18Z

there is also a fast approximate log2 PTX instruction, lg2.approx.ftz.f32, but I've never tried using inline PTX and I don't know if the CUDA ::log2f uses that or not.
