Present: Bill, Steve, Roland, Eloisa, Miguel, Chris, Eloisa, Ian, Sam, Qian
Tutorial: * needs some work to enable plotting when using console * Bill will test it * expect to get feedback from new users * would like to have it up before supercomputing (next week)
ET Jenkins server: * had hardware failure at NCSA, slow to tells users that system is back * should now be back * 6 failing tests ** prolongation one is new, need input from Erik, want trac ticket ** SphericalHarmonicReconGen: could be bug in the reader or in PITTNull code. PITTNull is sensitive to optimization since it includes the full Einstein field equations. Check if using -O3 instead of -Ofast would help. ** have generic.cfg and generic-opt.cfg, get rid of debian.cfg, ubuntu.cfg etc.
Working groups: * have sent email to individual (co-)leads for projects to write project description and add to wiki * Steve & Sam have new thornlist to test which thorns work * Eloisa & Helvi have draft of cosmology working group draft. Will have wider review next week.
ET call next week: * decide based on agenda by Sunday next week * Eloisa will host if needed Steve will add her to stevenrbrandt.org organization * Steve will send regular reminders
Software carpentry style tutorials * interest by persons at NCSA to have software carpentry type tutorials for a scientific code, suggested to use ET tutorials as a starting point * would provide existing tutorials to the person together with some help on how to use them
Standing items: * mailing list: Eloisa will contact Maria about what release she is running
Yours, Roland

It turns out that this was already discussed in the original ticket for the feature, https://trac.einsteintoolkit.org/ticket/2068, and was fixed in a pull request https://bitbucket.org/eschnett/carpet/pull-requests/19/correct-error-in-vert..., which was reviewed as OK by Roland in https://trac.einsteintoolkit.org/ticket/2074, but never applied. I just applied it. Hopefully it will fix the problems.

I would suggest that generic.cfg should be more conservative, since it is the default probably used by new users, and we don't want them running into edge cases caused by aggressive optimisations. Can we reduce the optimisation level in generic.cfg to -O2? Then we could have a generic-no-opt or something, which really had no optimisations at all.

Hello all,
I would suggest that generic.cfg should be more conservative, since it is the default probably used by new users, and we don't want them running into edge cases caused by aggressive optimisations.

For gcc even -O3 is value safe ie it can be applied without running into edge cases (it may however make compilation slower than -O2 of course).

It did. We are now down to three failing tests, all in SphericalHarmonicRecon and SphericalHarmonicReconGen.
