Present: Roland, Bhavesh, Erik, Jim, Peter, Roberto, Samuel, Steve, Yosef, Frank, Qian, Ian,
con2prim workshop at PI: * Erik had hosted a workshop to learn about current state of the art of con2prim methods and eos tables for hydro codes * Erik gave a quick report on what was learned at the workshop * good design should have a "cleaning" stage that removes non-phyisical points in a well defined manner so that the actual root finding can be robust * people interested in this: Philipp Moesta, David Radice, Wolfgang Kastaun big tickets items for the next release: * want to get them in now to have them well tested for next ET release * Roland, Ian, Steve have leftover "cleanup" tickets from the release * need to update trac landing page to point to current release new thorns: * GiRAFFE: make sure there is outside interest and push by authors * Lean-Public, Proca: make sure there is outside interest and push by authors * suggest third-party-thorns registration capability, add this to discussion items for next week BNS gallery example: * Roberto suggests the difference could be due to F90 vs C++ code, can check which code was originally used to compute the gallery example * Roland to re-run with code from time of gallery example creation to check on differences between clusters ET workshop at GT: * date (June 18th - June 20th) are fixed now * forming a scientific organization committee right now * working on registration procedure * will send url of website to users mailing list once known OpenMP scalability on Stampede SKX: * Jim is testing threading changes in OpenMP usage during prolongation by Erik * see this email for results: http://lists.einsteintoolkit.org/pipermail/users/2018-February/006093.html * finds ~25% benefit when using newer code * should update OpenMP settings in Simfactory to have more MPI ranks per node (right now uses 2 which is among the worst possible settings) Yours, Roland -- My email is as private as my paper mail.
