• Present: Steve, Helvi, Peter, Leo, Cheng-Hsin, Keith, Roland, Yosef, Zach, Johnny
  • seminar proposal: Adam J. Peterson, "Code generation for AMReX with applications to numerical relativity", 2301.08354, which uses AMReX for Z4c evolution
    • March 09th, recording available on seminar page and youtube
  • Unanswered questions on mailing list
    • email from Roland: nobody used Anvil before
    • [SB] Another email regarding running on Rome powered supercomputer: [RH] Delta is powered by Rome, Steve or Roland will ask the user to provide the files for compiling (optionlists, etc.) and send this email to the mailing list
    • New GRMHD library: take IllinoisGRMHD and NRPyEOS and make it into a library, [LW] No need to review NRPyEOS and NRPyLeakage, will need reviewers for other parts. Terrence will review particle code, Peter can review NPSolverSX (?), [HW] have reviewers and champions in contact
    • [RH] People who agree to test the cluster, Steven Brandt - deep bayou, Peter - sunrise, Roland - stampede2, expanse, Summit, Frontera, [LW] add detail to the release
  • Open tickets
    • SummationByParts: [RH] prefix needs to be fix to not pollute namespace, fix name conflict when Fortran code add underscore at the end, warning: might break something in Llama
    • Mac os Ventura: [RH] duplicate from the mailing list, could be listed as solved
    • Compile on the M1 system [RH] PAPI needs significant changes, HomeBrew changes the links
    • Slab fails [RH] Slab claim to optionally use MPI and Kranc tutorial did without it, but it actually does use MPI so a pull request is made to fix this
    • Include NRPyLeakage [LW]: will be included for the next release
    • EHFinder parfile: [PD] will look into it
    • [YZ] Large ET jobs on Frontera, startup overwhelming the system, every MPI proc starts reading files. Proposed solution: at a checkpoint, only a group of MPI procs to open files, workaround by staggering when the job starts, issue might also occur with CarpetX. [RH] Assign token barrier to MPI. Roland can send the token to Yosef. Frontera should fix their file system.
