If you are part of a group, it may be beneficial to have your ini file checked in to simafactory (after it is debugged and tested) so that other members of your group have access to it.

The automated setup command `setup` or `setup-silent` is only designed to set up simfactory on a workstation, not a cluster. Clusters are complex and individual enough so that a simple script does not work and you will have to manually adjust or set up things (eg the queuing system). See eg: https://www.einsteintoolkit.org/seminars/2022_02_24/index.html and the wiki documentation https://docs.einsteintoolkit.org/et-docs/Configuring_a_new_machine Note that under the hood this all just uses your cluster's queuing system, and you can also "run your own" sbatch script using eg an example provided in the cluster's documentation: --8<-- #!/bin/bash # various SBATCH or similar options # eg 4 threads per MPI rank export OMP_NUM_THREADS=4 # 16 MPI ranks srun -n 16 --cpus-per-task $OMP_NUM_THREADS cactus_sim myparfile.par --8<-- Yours, Roland > Hello, > > I am trying to run the static_tov simulation on my university's cluster (CRC > Notre Dame ).

I cannot tell for sure since I do not know how long you ran the simulation. My first guess would be that the waveform has not yet had time to travel to the location of the detector at r=500. Since the source is the black holes at about r=0 it will take the wave about 500 time units to travel the distance of 500 space units (speed of light is c=1 in the simulation). A second issue to consider is that if you have multiple output-NNNN directories then you have to first concatenate the output data file to have access to all data. Specialized analysis tools like kuibit, SimulationTools and PostCactus (see https://docs.einsteintoolkit.org/et-docs/Analysis_and_post-processing) will usually do this automatically but if you use your own Python or gnuplot code then you will have to do so yourself.

The TOVSolver thorn in the Einstein Toolkit does not directly output its (1D) result anywhere but instead directly interpolates to the 3D Cactus grid. You could edit the source code (in tov.c there should be a function called solve or so and a function that interpolates, you can look around for the `for(k = 0 ; k < cctk_lsh[3]; k++)` or so loops which are where the interpolation to the 3D grid happens. Just before will be the 1D solve. Having said that the NRPy+ code also has a TOVSolver (in Python and with some C code generation as well I think) that you may find useful. Your best chance is probably to contact the NRPy+ developers (who are usually subscribed to this mailing list). The TOVSolver is here: https://github.com/zachetienne/nrpytutorial/tree/master/TOV and the person to contact is most likely Zach Etienne (see https://www.nrpyplus.net/download-en_US.html).

When generating the initial data of lower binary mass, I noticed the discontinuities have become more notable and is not fit for running the follow-up numerical simulation. I add the energy distribution of the initial data of the standard mass BNS and the low mass BNS, respectively, in the attachment. It clearly shows the ripples at the star boundary.

The expected_merger variable is, as far as I recall, only used to "size" the domain so the exact value is not extremely critical but should be about (and ideally not much smaller) than the actual merger time (eg based on a post-Newtonian prediction). If possible, please keep users at einsteintoolkit.org in the addressee list so that ohters can find this resolution as well.

So I will only describe things without hyperthreads (which mostly just add a complications). With that in mind simfactory's './simfactory/bin/sim setup-silent' should do a good job at setting up a default machine description. When you submit you should set ppn-used to the number of compute cores you will use, one per OS thread. So with 16 threads you would use ppn-used to 16 as well. If you are looking to get most speed on a typical workstation (single node) then most likely you fastest way is actually to use 1 thread per MPI rank and as many MPI ranks as you have physical cores. So something like: --cores 6 --num-threads 1 --ppn-used 6 in your case. Yours, Roland > Hello everyone! > > > > > I?m new to the ET. I have the ET installed on my desktop.

The sentence ends here. Ah, I was going to suggest this as a topic for the working workshop / hackathon at RIT end of July. Since there are are least 2 groups interested (RIT and UIUC).

It would be great if you could bring this to the attention of potential candidates. Regards, Anuradha ------------------------------------------------------------------ The Institute for Gravitational and Subatomic Physics (GRASP) at Utrecht University is looking for a highly motivated PhD candidate in gravitational-wave astrophysics. As the successful candidate, you will work with real and simulated gravitational wave data from existing detectors as well as envisaged next-generation observatories such as Einstein Telescope, use statistical tools such as Bayesian analysis to assess what the challenges will be, and develop novel methodology to analyse the data accurately. With the developed methods, you will likely be placing much more stringent bounds on fundamental constraints from third-generation detectors. You will join the international Einstein Telescope Collaboration as well as the LIGO-Virgo-KAGRA Collaboration, and are expected to participate in analysing data as part of the latter. You will work in the group of Dr Anuradha Samajdar, and you will be an active member of the broader Dutch consortium in gravitational waves. Other staff members working on gravitational waves within GRASP and the Department of Physics are Professor Chris Van Den Broeck and Dr Tanja Hinderer.

For the different models? o I gather we have several models/codes: GRHydro and IllinoisGRMHD, so resources on those would be much appreciated. o And initial data readers exist for the LORENE (1 and 2?) and for the FUKA data...resources there might be helpful too. I am hoping for some introductory information (a review would be great) on all our fluid codes, as well as other codes used in other numerical relativity systems. Some context:?

I'm writing to you as per indication in Step 7 at https://illinoisgrmhd.net/getstarted.html. I'm currently working in IMBH hierarchical mergers in AGN discs, and I think it'd be good for my project to use the code IllinoisGRMHD, as it considers 3D effects in the GRMHD phenomena around BHs. However, I've found a couple persisting issues at installation. I'm running on a Windows 11 Pro WSL x Ubuntu 22.04.2 LTS "Jammy Jellyfish". At Step 0, I have made sure to install a fully functional version of the Einstein Toolkit. 1. As per indicated in Step 4, I went to the file ubuntu-Intel.cfg (attached), as referred by my version of make_config-runmefirst. I was able to apt-get install all the packages referred in the preamble of ubuntu-Intel.cfg, except for libmpich2-dev, so I installed the closest packages available to apt-get: libmpich-dev and libmpich12. 2. At Step 4, when I try to ./make_config-runmefirst, I get the following error message: checking whether the C compiler (icc .-xhost -openmp -0fast -align -std=gnu99 -rdynamic) works... no configure: error: installation or configuration problem: C compiler cannot create executables (see configs//config-data/config.log for details). Error creating configuration etilgrmhd make: *** [Makefile:762: etilgrmhd-config] Error 2 I am attaching config.log as config.log for reference as well, as config-1.log. If I change CC = icc in ubuntu-Intel.cfg to CC = gcc (which afaik my machine has installed), I get the same error message, but with a different config.log (attached as config-2.log), telling me about an unrecognised -align option. If I remove the -align flag from CFLAGS in ubuntu-Intel.cfg, I get the same error message with another config.log (attached as config-3.log), telling me about a host language not being recognised. And, lastly, if I change the -xhost flag in CFLAGS to -xc or -xc99, the same thing happens. The config.log file of this last option is attached as config-4.log. At this point I don't know what else to try to get a running version of IllinoisGRMHD. To be honest, I don't really know much about bash yet, so I was hoping you could provide some support about my installation issues. I will be happy to answer any questions necessary.

Yup, overly broad I know.? So more specifically, o Are there good reviews, references, or lectures that describe how we currently handle fluids?? For the different models? o I gather we have several models/codes: GRHydro and IllinoisGRMHD, so resources on those would be much appreciated. o And initial data readers exist for the LORENE (1 and 2?) and for the FUKA data...resources there might be helpful too. I am hoping for some introductory information (a review would be great) on all our fluid codes, as well as other codes used in other numerical relativity systems. Some context:? I rub elbows with mathematicians who work in relativisitic fluids (ideal, viscous, etc) and they do not believe that any codes out there can do fluids "correctly."?

Since that does not seem to work for you, would you mind including the full parameter file you were using as well as the full output to screen / the log files? Both stdout and stderr. If you just see not output files then first I would check that I am expecting the correct files. Extract uses its own filenames and not the "usual" .asc files. Namely, looking at the test output they end in .ul and .tl (no idea what they contain though). Second check that you are actually asking for output, eg the test parfile has extract::itout = 1 Best may be to run exactly the test parfile with your executable to check that you get the expected output (you can do that without mpirun or simfactory most likely, using cactus_sim qc0-mclachlan.par directly).

I would like to work on > some codes for my project. Depends on what you mean by "work on gravitational waves", which is a large area of research. The toolkit is used for numerical astrophysics and gravitational waves produced by colliding compact objects have been a long standing target for these types of simulations. Eg the GW150914 gallery example: http://einsteintoolkit.org/gallery/bbh/index.html contains an extensive set of Mathematica notebooks that show how one can process the gravitational waves produced. If you are thinking of eg post-Newtonian work, then no the ET is the wrong toolkit for this. If you are thinking of extreme mass ratio inspirals then the black hole perturbation toolkit https://bhptoolkit.org/ may be useful for you. To get an idea what the ET is currently being used for you can query eg the arXiv for it: https://search.arxiv.org/?in=&query=%22Einstein%20Toolkit%22 which gives some idea of what it can be and is used for.

Many of these codes have changed since the papers, but the fundamentals are there.? To my knowledge all current public codes handle ideal hydro (i.e. no treatment for viscosity) and radiation hydrodynamics are usually limited to grey leakage schemes.? Also resistivity has seen limited implementation even in closed-source codes. You can also look at the initial data videos from the EinsteinToolkit youtube channel which discuss Lorene in quite some detail and there are a couple of videos on FUKA initial data as well.? Hopefully the videos from the US conference that just took place will be posted soon as FUKA has changed quite a bit in the last year. A web reference for FUKA can be found here samueltootle.github.io/fuka including reference papers.
