Addition of saturated flag in SiStrip Approximate Clusters #38870

abaty · 2022-07-27T12:34:15Z

This PR slightly extends the SiStripApproximateCluster data format to include a boolean flag which marks clusters which are saturated. This change was motivated by the discussion at [1]. The definition of 'saturated' we use here is the same as what is used in the SubClusterShapeFilter, i.e. a cluster having 3 consecutive strips of ADC>=254. Note that this flag is not currently used in the reconstruction sequence; this PR is simply to ensure this information is not dropped in the new approx. cluster data format. This is expected to increase the approximate cluster collection size by ~1% and barely affect the timing performance [2].

PR validation:

This PR was tested by running workflow 140.58 step 2, and checking the approximated cluster collection in the output.

why did it jump from 3 -> 9?

I have updated this file to be version '4' now.

jpata · 2022-08-02T11:59:29Z

The size increase overall seems negligible, so once the class version is sorted out, it's good to go from my side.

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. @perrotta, @dpiparo, @qliphy, @rappoccio (and backports should be raised in the release meeting by the corresponding L2)

This should have kept the checksum for class version 3 in addition of 4.

Thanks Matti. Is there a way to detect this at compile time (or in the tests)?

Nothing straightforward comes to my mind, but maybe we could figure out something. A specific check would certainly help to catch such cases. Could you open an issue about it?

done! #39008

As pointed out by @makortel cms-sw#38870 (comment), we forgot to keep the old class version in cms-sw#38870.
