<br>
present: Roland, Lorenzo, Jay, Yosef, Federico<br>
<br>
hydro toy code<br>
* Jay ran a trial for shock tube using low resolution (100 points<br>
total) comparing HydroToy and Spritz. Both do similarly well, if<br>
anything Spritz does worse since Spritz has the wrong value on the<br>
left hand side of the shock, while HydroToy's was more correct.<br>
* Jay will run some more of the Balsara tests<br>
* Jay to send around plots with results to mailing list<br>
<br>
ET summer school talk<br>
* Jay, and Federico and Lorenzo (in order of involvemet), will contact<br>
Leo who is the executive organizer<br>
* target audience would be ET developers who want to use GPUs in the<br>
ET, which is facilitated by CarpetX<br>
<br>
late TODO items:<br>
* Roland has not yet worked on the unit test for HydroToy<br>
* no decision on new (if any) name for GRHydroToyGPU yet, "Primavera"<br>
or "GRHydroX" were suggested.<br>
