Compiling ET_2023_11 on Sciama
by Robyn Munoz 22 Feb '24

22 Feb '24

Hi everyone, I've been unsuccessfully trying to run the latest version of Einstein Toolkit on the Sciama HPC cluster where I have been using the 2020_05 version so far. Could someone please help? I have tried three different approaches and put the terminal output and config.log files of each in the folder here (too heavy for email)Compiling_ET_2023_11_on_Sciama - Google Drive as well as the Sciama config files I used in the B approach. A) Using the config files already included in Einstein Toolkit, using intel_comp/2019.2 it gives the error Cactus requires a C++11 compiler -- check your C++ compiler and C++ compiler flags If using g++ at least version 6 is required, if using icpc use -gxx-name to use libstc++ from g++ at least version 6 I tried using intel_comp/2020.1 (the latest available on Sciama) and got the same error (and some module warnings). I found the path to g++ and so tried to add -gxx-name = /opt/apps/compilers/gnu_comp/cfg/9.1.0/intel64/bin/g++ to CXXFLAGS in sciama.cfg but this didn't change anything. B) Using gnu_comp/13.2.0 instead, I changed modules and flags where you can see in the Google Drive folder the .ini and .cfg files I use. It compiles all the way to the part "Creating cactus_sim" where it lists all the thorns then I get lots of errors of the type patch_system.cc:(.text+0xbe): undefined reference to `H5open' /usr/bin/ld: Dwarf Error: found dwarf version '1', this reader only handles version 2, 3 and 4 information. I have this message for lots of files .cc, .c, .f90 undefined reference to lots of different H5 functions (and also dsytrf_ dgetrf_ dgesv_ dsysv_ dposv_ dgbsv_) complaining about dwarf version 'any number'. The only other somewhat similar example I found of this online is here https://github.com/tinygo-org/tinygo/issues/1415 but it's not that helpful. I'm guessing it's unhappy with hdf5, unfortunately, the latest version on Sciama is 1.10.5. Do I just need a later version of hdf5 or is this something else? C) I tried with the EinsteinToolkit hdf5 (that I see is version 1.12.0) with HDF5_DIR = BUILD and commented out HDF5_LIB_DIRS and HDF5_INC_DIRS, as it compiles it doesn't get as far. In the output, I'm under the impression it manages to build it properly, but later it seems to not be unable to find it, but it should just be within Einstein Toolkit right? Thank you for your help,Robyn

Re: [Users] Parameter file for a binary BH merger immersed in a scalar field
by Roland Haas 16 Feb '24

Hello Samuel, Sorry for the long delay in responding. We are experiencing some issues with the mailing list making incoming emails not be correctly forwarded all the time. Thank you for your interest in the toolkit. The thorns in the Canuda repository (ScalarBase, ScalarEvolve, etc.) would indeed seem to be suitable for your application and somewhat similar research is being done in Helvi Witek's research group at UIUC, who is also one of the maintainers and authors of the Canuda code. I believe that e.g. initial data can be produces using eg the TwoPunctures_KerrProca thorn (or a slight modification of it if a scalar rather than a Proca field is required). I have put her and the other maintainers (as listed in the README file) in CC. They may most likely be able to provide more detailed comments (or redirect you to a colleague closer to your timezone that can help).

Present: Sam Roland Steve Zach Peter Leo Spec benchmarks We made it to the second stage, so they should combine both and send the check to Steve. Proposed release contributions (and code champions): Multipole (Lucas) NewRadX (Cheng-Hsin) Z4c (Erik) Baikal/BaikalVacuum (Sam) generated from NRPy 2.0 Baikal/BaikalVacuumX (Sam) NRPyPN (Zach)generated from NRPy 2.0 FUKA? GRHayLHD update for tabulated EOS IllinoisGRMHD updated to use GRHayL Compilation on Mac homebrew: Roland has made some progress Might require backports of changes to external libraries Other issues with e.g. FLRWSolver due to difficulties in build system Tickets Issue #2770 fixed in master needs to be backported to previous release Issue #2774 Lots of details, reproducible examples given by Jose Next week's chair - Sam Next week's minute taker - Leo
