Invitation to join cosmo working groups * if interested, please join the mailing list as outlined in the email by Helvi at: http://lists.einsteintoolkit.org/pipermail/users/2018-January/006021.html

Failing tests in PITTNullCode: * Yosef tracked it down to a compiler bug. The only affected code is the test, regular code in the thorn does not use the failing combination of operations. A bug report has been filed with the gcc developers * would like to find out which versions are affected * will follow Yosef's suggestion and remove the test

Release status: * test are in the process of running on clusters * have to find out (again) how to populate http://einsteintoolkit.org/testsuite_results/index.php * had release status meeting on Friday and could clarify most issues * details are here: https://docs.einsteintoolkit.org/et-docs/Release_Details * Ian created tickets for the otustanding tasks (marked with the milestone) in the trac system * code name "Tesla"

OpenMP scaling: * Jim ran openmp-tasks version on Stamped2 Skylake * running on larger number of cores (~24 nodes) one sees an improved runspeed using the task based prolongation compared to either the old code or the new code with the options turned off * this test used 11 reflevels and fairly high resolution * Erik points out the importance of thread binding in Cactus which requires the SystemTopology thorn. Jim will re-run with that thorn active (~256 iterations is enough). Should also post the stdout files where Carpet lists thread binding results

ET US meeting at GT: * dates have still to be finalized

Yours, Roland
