ET spring workshop: * will announce ET workshop together with Caltech school on astrophysics gravitational waves [1] Site is currently under construction so content may change. * the new user workshop will be *one day*, Friday July 26th * the summer school before should cover the theory part, eg. BSSN and astrophycis and gravitational wave theory * preliminary program outline is on wiki [2] * old meeting notes on user workshop:

• next new users workshop will be attached to Caltech summer

school on astrophysics. School runs July 22nd - July 26th (incl.).

• students of summer school housed in dorms, extra attendants will need

to book hotel rooms (dorms would need to know how many rooms in advance [now]).

• will have 1 day intensive program on Friday (from past experience; we

want to offer an early bird setup session the day before or before the workshop starts, we do not want to loose time on this.)

• program suggestions:

• gear towards astrophysics (less binary black holes)
• consider other components than Cactus, eg. GR1D
• generic computational methods: OpenMP, OpenCL, CUDA, (since new

clusters with accelerator architectures will be online by then)

• a wiki page for the workshop will be created

(https://docs.einsteintoolkit.org/et-docs/index.php?title=ET_Workshop_Summer_...), please list yourself if you want to volunteer for a section of the workshop

• attach developers workshop after new users workshop, ie. on Saturday,

Sunday and Monday

• pick one topic for developers workshop, prepare this in advance, focus

on this during workshop

* suggestions for the hands on coding are to write a simple center of mass routine (not the more fancy one we tried before, just one that produces output to disk).

* developer's workshop right afterwards on Saturday and Sunday. Need goal for this workshop.

GRhydroMP presentation: * current plan is to use webex. Instructions on how to use are to follow. * Erik will be host * date: next week Feb 5th

Yours, Roland
