[Users] meeting minutes for 2017-07-03

[Roland Haas]

Hello all,

> Some remarks:
> 
> - What machine is 105aff02?
Machines with just hexadecimal names are my laptops.

> - Why are the Dissipation testsuites failing on
> BW/Comet/Edison/Cori/Golub/Hydra? (ADMConstraints? ... see below) On
> BW they don't seem to produce output at all, but on the others the
> same number of sufficiently different files suggest a common cause.
> - sphere_pugh_ppm is one of the 'fails a bit sometimes' thorns, and
> has   been for a while. It's not a release-blocker, but a candidate
> we should look at. This might very well be a not optimal testsuite
> setup.
> - RotatingSymmetry90/180 testsuites also seem to fail on
> Golum/Edison/Cori. I seem to remember that, like Dissipation, they
> use ML_ADMConstraints results in the testsuite. Could you please

> - We should probably disable OpenCL for BW if not even the WaveToy

> should work.
Would you mind adding those comments on the wiki page that I had
mentioned in the minutes, please? That way they are in one place and
not scattered throughout multiple emails.

https://docs.einsteintoolkit.org/et-docs/Release_coordination

which already has sections for the different machines and has my
assessment on the BW issue and at least one guess for the failure of
Dissipation (though the SEGFAULT on BW persists).

> Overall, this looks really quite good - in fact, better than at some
> other times for a release.
Yes.

> Keep adding/updating testsuites, I'll prepare release notes and get
> everything ready for a release. For now, I will not create release
> branches before that status of ML_ADMConstraints is sorted out (patch
> is in the works, but not in master and not widely tested yet).
Ok, thank you.

Yours,
Roland
