Fwd: need help running simulation on slurm
by Maya Baireddy 30 Nov '24

30 Nov '24

Hello Everyone, I am new to ETK. I am working on my high school research project trying to run the simulation of BNS merger on amarel supercomputer from my local university. Could you please help me to start my simulation on SLURM. I have followed the ETK gallery example for BNS simulation steps 1-5. But I am not able to proceed to successfully create a machine to run the simulation. I run the following steps /home/sb1554/BNS/simfactory/bin/sim create bns --parfile /home/sb1554/BNS/bns.par --machine slurmbns srun bns.sh -o slurm.bns.%N.%j.out and got the error: **** An error occurred in MPI_Init_thread*** on a NULL communicator*** MPI_ERRORS_ARE_FATAL (processes in this communicator will now abort,*** and potentially your MPI job)* I am attaching my machine, submit script, run script, log files. I would appreciate any pointers from you. Or if you could point me to the right person. I was trying to post this on EKT forum, but need one credit to post. Thank you, Maya

https://docs.einsteintoolkit.org/et-docs/Main_Page#Weekly_Users_Call Minutes ET 20241114 9am CST Attending: Zach E, Lucas TS, David B, Leo RW, Maxwell R, Bill G, Steve B Chair Leo RW, Minutes Bill G Agenda https://docs.einsteintoolkit.org/et-docs/Meeting_agenda * Relase timeline https://docs.einsteintoolkit.org/et-docs/Release_Details#Schedule ** Announcement Roland, just finished draft of release announcement. Check it out and send any comments/corrections. https://www.einsteintoolkit.org/about/releases/ET_2024_11_announcement.html ** Contributors Roland, A little behind on contacting new contributors. David needs to tell us all the contributors to TOVola. ** Tests Roland, Behind on testing of the different clusters. Steve on Docker containers. Maxwell also testing, OpenPPD failed. Steve, had to switch form OpenMPI to MPIch, OpenMPI not working on Docker. Has one test that fails. Docker containers are all good. And can share the install command for each of those. Roland, then we can update the Jupyter notebook.. Roland, can compile on his clusters but not run tests yet. Grahyl has a failing test. Leo is looking into it. Roland, issues with HDF5, can set to use external library. Should put in that in the Jupyter notebook. Leo, probably not looking for different values in the list. Maybe chaning the list is too invasive for a few weeks before release. Roalnd, Could back port it into the release after testing it further. Steve, testsuite on any LSU machines? Roland, Maybe DB1. Steve is signed up for all the LSU machines. Roland not able to login to other machines at LSU. Steve should receive requests for permissions. Steve added LONI allocation for Roland to run on those LSU machines. Steve still assigned the testing. Roland, trying to install more of the CarpetX so moving from Intel backend to LLVM-based so oneAPI compilers that are Intel can compile this, have better C++ support. * Unanswered questions on mailing list None. * Open Tickets #2830, CarpetX depends on BLOSC Not in the Toolkit. Roland has poked Erik. #2173, #2174, #2176, #2172 Poisson, Multi-Patch, BNS, GW150914 Gallery examples David needs write access, to upload the tar file to downloads folder. Roland will check on login to BitBucket and give access. #2818 Failing tests with GCC14. Roland, will close it, there is a warning coming out for AMRex. #2520 update gauge settings in TOV example David, will be uploading the gauge examples too. #2171, and other old tickets Roland poked them to bring them high on the list. * Tickets for Review #1566 Update Cactus autoconf Roland, do not want to make the change this close to release. Currently using very old 2.13 (1999) and new is 2.72 and using the automatic script still needs some manual changes. So needs more testing. New Autoconf has advantages for many machines. Review the configure.ac . [ https://www.gnu.org/software/automake/history/automake-history.html January 1999, Automake 1.4 and Autoconf 2.13 https://ftp.gnu.org/gnu/autoconf/ December 2023, Autoconf 2.72 ] #2761 some ExternalLibraries require cmake to build Roland, several clusters do not have new enough cmake, wants 3.22 version. Steve, for Docker had to install cmake package for each of them. #2920 NewRadX boundary condition conflicts with symmetry condition Roland, would like to have had it in. A two commit issue, one for NewRadX and one for CarpetX. #963 Improve McLachlan accuracy Roland we should get this in next time. * Any Other Business None * Next Week: chair Zach, minutes Leo Steve is at SuperComputing next week. -- Dr. William Gabella

hybrid star setup in the TOVSolver thorn
by CJ Osakwe 07 Nov '24

07 Nov '24

Hello, I am trying to set up a stable hybrid star (with a quark matter core and hadronic crust, each with their own equation of state) in the Einstein Toolkit. My initial approach was to adapt the TOVSolver thorn to achieve this, but the code is removing the density discontinuity at the hadronic-quark matter interface when it interpolates from 1D to 3D. As well the discontinuity doesn't seem to be reflected in the pressure anyway. I'm wondering if there is a thorn that is better suited for setting up a stable hybrid star? Cheers, CJ Osakwe PhD candidate, Department of Physics and Astronomy University of Calgary
