Compiling failure on Mac with Apple Silicon M2 chip
by Yufeng Luo 10 May '23

10 May '23

Hello, I was trying to compile ET_2022_11 on a M2 Macbook Pro machine, but I got an error. I attached my compilation output below. It seems that the general configuration script correctly recognized my machine with a aarch64 (line 50) processor, but when compiling openSSL thorn (line 2933) the compilation script incorrectly marked the machine as i686. My understanding is that apple silicon (M1) is now supported in the newest version of ET (2022 11). Since M1 and M2 have the same ARMv8 architecture, I was wondering if there is an error in openSSL thorn? Thank you. Best, Yufeng

Present: Roland, Peter, Zach, Gabriele, Leo, Sam ET release timeline =================== * release date will be May 24th * Leo and Sam are sending emails to the contributors and drafting the release announcement * inclusions are reviewed ok kuibit ====== * Gabriele finds that installing kuibit using pip is getting harder and coming up with generic instructions is difficult * Ubuntu 23.04 (and other new versions) prohibit use of `pip install --user` and strongly favor virtualenv * Also link required package instructions as described in https://bitbucket.org/einsteintoolkit/tickets/issues/2724/update-download-p… Testsuite status ================ * no updates * test need to be re-run after fix to Fortran AliasedFunctions code * Peter will re-run on sunrise once release branches are in place * Roland has updated tests for Frontera and will re-run other tests * Anuj will re-run tests on thornyflat Gallery tests ============= BBH: no update BNS: Roland updated example TOV: Peter will run Multipatch: no update Poisson: no volunteer, Leo and Sam to look for people Gabriele suggested to have more detailed change list listing bugs more explicitly * Zach suggests using the script that shows changes for review by the release managers * Gabriele suggests providing a link to this information, also to resolved tickets * link to revolved and closed tickets sorted by date: https://bitbucket.org/einsteintoolkit/tickets/issues?status=resolved&status… questions ========= * Gabriele mentioned large number of warning messages from Cactus when trying to run lean_public with presync_warn flags https://bitbucket.org/einsteintoolkit/tickets/issues/2723/no-boundary-condi… ** there was some more generic discussion about how presync handles it various options * Leo brought up about HydroBaseX for CarpetX where currently there is no direct way to handle staggered variables ** this is more generic problem with variables that may sensibly be defined or used with different sorts of staggering. Current HydroBase assumes a single global choice is good enough for all codes that interface and that translation between representations is almost error free. emails ====== * existing emails by Shamim Haque, in conversation with Steve, ask Steve if is continuing the converstation tickets ======= * https://bitbucket.org/einsteintoolkit/tickets/issues/2722/getcomponents-pla… is needed for release, Roland will ask Steve chair next week: Zach minutes next week: Steve Yours, Roland -- My email is as private as my paper mail.

Compilation Error in cluster ParamGanga
by Shamim Haque 1910511 03 May '23

03 May '23

Dear all, We are trying to compile ETK on ParamGanga at IIT Roorkee. The compilation stops at a very initial step and gives out the error: *checking whether the Fortran compiler (gfortran ) works... yeschecking whether the Fortran compiler (gfortran ) is a cross-compiler... nochecking whether the Fortran compiler (gfortran ) supports TYPE(*) for CCTK_PointerTo... yeschecking how to run the C preprocessor... cppchecking for ANSI C header files... nochecking for C99 features... yeschecking for M_PI... noconfigure: error: M_PI not defined. Try adding -D_XOPEN_SOURCE to CPPFLAGS.* We tried adding -D_XOPEN_SOURCE to CPPFLAGS, but it does not help. This error is consistent if we set up using Intel Compiler (2020 or 2019), or gcc (11 or 10). I have attached the outfile, error file, machine script, and option lists for both cases (Intel and gcc) for any reference. Secondly, we are not allowed to compile ETK on login nodes. So we are queuing a job script, which upon execution, enters the Cactus directory, does "setup-silent", and then executes the build command. Is this the right way to compile ETK using the batch script? Or should we do something different? I have attached the shell script (compile.sh) used for sbatch queue for reference. Thanks in advance for the help. Regards Shamim Haque Senior Research Fellow (SRF) Department of Physics IISER Bhopal ᐧ

Warning: No boundary conditions registered for variables in group LEANBSSNMOL
by Vikram Manikantan 01 May '23

01 May '23

Hi, I am a new user of Einstein Toolkit, using the latest version (ET_2022_11). I have recently encountered issues with the Lean thorn that lead to warnings concerning the registered boundary conditions. I filed a bug report here <https://bitbucket.org/einsteintoolkit/tickets/issues/2723/no-boundary-condi…>. And possibly related to issue #2651 <https://bitbucket.org/einsteintoolkit/tickets/issues/2651/new-warning-messa…> . To reproduce the issue, just add the line Cactus::presync_mode = "mixed-warn" to the *Lean_inspiral_d06_mres.par *file in repos/lean_public/par/. The warnings I get look like: -> No boundary conditions registered for variables in group LEANBSSNMOL::GAMMAT. The unregistered variable(s) is(are) LEANBSSNMOL::gammatx, LEANBSSNMOL::gammaty, LEANBSSNMOL::gammatz. There are hundreds of lines like this. Is this a concern? I am happy to produce any extra information needed. Thanks! Best, Vikram

The 2023 North American Einstein Toolkit School and Workshop will be held at the Rochester Institute of Technology on July 17 through July 21. This will be a hybrid conference with talks and participants both in-person and over zoom. The Einstein Toolkit is a community-driven software platform of core computational tools to advance and support research in relativistic astrophysics and gravitational physics. The conference consist of a mixture of tutorials for new users and talks about the latest developments both in the toolkit and the larger scientific community. A preliminary schedule and links to the registration page can be found at https://compact-binaries.org/content/events/2023-07-17/north-american-einst… Registration is now open and remain open until June 17, 2023. As part of the registration process, potential attendees can apply for partial travel support. In order to be eligible, applications must be received prior to June 1. Notification of partial travel support will be made by June 8.
