[Users] meeting minutes for 2018-08-27

[Bruno Giacomazzo]

Hi,
  just a quick note that I use Marconi A2 and A3 without problems. I will
check with the latest stable release. With the previous one, I needed very
minimal (and very easy) changes to the config file and submit script.

Cheers,
Bruno

> Gallery examples for next release:
> * BBH: comparison between current code and gallery data in Zenodo,
>   results are pretty close. Plots are here
> http://lists.einsteintoolkit.org/pipermail/users/2018-August/006471.html
> * poisson: Roland updated code, with this he can reproduce the plots,
>   updated the website
> * BNS: Peter found out that change of using EOS_Omni to compute
>   quantities cause most of the initial differences, after merger there
>   are still differences. So far no input from Frank or Roberto, Peter
>   will contact them directly.
>
> Reviews:
> * WVUDiagnostics: no progress, want testsuites. Push to next release
>   unless we have tests soon.
> * GiRaFFE: main thorn reviewed, most of GiRaFFE_Food, Zach and Roland

> Documentation:
> * would like some documentation explaining how to set up checkpoint /
>   restart
>
> IllinoisGRMHD robustness:
> * Zach reduced the maximum allowed speed to have a max. speed less than
>   c_light
> * finds that robustness is greatly increased if one uses 3rd order
>   Lagrange interpolator for IllinoisGRMHD variables. There is a pull
>   request for such an operator:
> https://trac.einsteintoolkit.org/ticket/2189
>
> Testsuites:
> * remove MPG machines: draco, minerva, hydra are MPG machines. Wolfgang
>   said he could maybe run on one of them, if not then we will remove
>   them
> * Peter will run smic
> * Marconi: a machine in Italy, Roberto de Pietri, Eloisa had access, if
>   they cannot run, then we should remove them
>
> Moving website to github:
> * may be difficult to move due to multiple repos being linked up
> * some pages use php and cgi which are not straightfoward to run from
>   github
> * currently have docker image that makes the server much more
>   self-contained than before, docker image is here:
>
> Working group calls:
> * IllinoisGRMHD on Wednesday 11:00AM US Eastern Time
> * Performance optimization on Friday 12pm US Central time
