Dear Colleagues, (apologies if you receive the same announcement multiple times) Registration has opened for the 30th Texas Symposium on Relativistic Astrophysics, taking place in Portsmouth, UK from Sunday 15 to Friday 20 December 2019. As convener of the parallel session on Gravity/Numerical Relativity, I would like to encourage you and your colleagues to submit an abstract for this session. Deadline for abstract submissions is the 27th of September 2019. Notification of acceptance will be on the 14th of October. Registration for early-bird fees will end on 25 October 2019, and general registration will close on 22 November 2019. More information on the symposium is appended below. I hope to see you in Portsmouth in December.

CactusTutorial
by Tomas Andrade 28 Aug '19

28 Aug '19

Hi, I am running the CactusTutorial online. In the section 'Prerequisites', we are told to install a few packages (xcode, gcc, git, etc). To try to do so, I opened a terminal within Jupyter, and typed sudo xcodebuild -license I got the error message: /bin/sh: 1: sudo: not found So, I can't download any of the prerequisites. I am able to continue and download Cactus with 'GetComponents' and run 'simfactory', but the build of 'einsteintoolkit' fails due to lack of the C compiler. Any advice? thank you!

QK Frame
by Carlos Lousto 28 Aug '19

28 Aug '19

Hi, We have been working with my student Nicole to define a global (not merely asymptotic for extraction) quasi-kinnnersley tetrad starting from a frame (psi1=0=psi3) and we were wondering if anyone in the collaboration have implemented it (or tried to) since we are finding difficulties when evaluated close or in between the black holes. Thanks, Carlos Lousto https://ccrg.rit.edu/user/carlos.lousto >

When compiling on my laptop which runs Ubuntu 16.04 I get the following errors: make[1]: *** [/home/mattia/Cactus/configs/sim/config-data/make.thornlist] Errore 1 Makefile:256: set di istruzioni per l'obiettivo "sim" non riuscito make: *** [sim] Errore 2 the second line says something like: th set of instruction for the objective "sim" has not succeded What does it mean?

Present: Frank Loeffler, Steve, Peter, Bill, Zach, Helvi, ... (I forgot to write this down during the meeting, please let me know if I missed you) Does HARM have an advantage over Cactus for neutron star evolutions? - It can excise the center of the grid and possibly the z-axis - Cactus lacks spherical coords, however Spherical GRMHD should help, also Spherical BSSN Code (Zach added all optimizations) - Zach is working on magnetized BNS merger, letting Harm do the long term evolution using a static spacetime Developing a handoff code. A new driver thorn based on AMReX is being developed: AMReX https://amrex-codes.github.io/amrex/ ETK meeting in London 2-6 of September Schedule will be up soon Zenodo DOI. List of names is complete. Still filling in people Plan is to sort anyone on the list who participates in the release to the top. Release - Peter's code in the ET - Separate checkout from the ET, but with the same tag. - Steve is reviewing Peter's code, help would be welcome - Zach wants the Fishbone Moncrief thorn to be included. Generates NRPy but NRPy is not required. Zach noticed that his recent NRPy code is 20% slower with the Intel compiler.

Present: Chris, Maria, Yosef, Peter. Self-force code in ET: * Steve has started reviewing the code. Buffer zones: * Yosef asked what the status is on implementing Bishop Mongwane's mesh refinemement scheme to get buffer zones. Nobody on the call remembered so we pass on the question to the community. Yours, Peter

Issues compiling ETK on Blue Waters
by Federico Cipolletta 15 Aug '19

15 Aug '19

I am experiencing some issues compiling the ETK on BW. The command I use is the standard command for simfactory, where I specify the machine as follows: ./simfactory/bin/sim build ETK_standard --mdbkey make 'make -j16' --machine=bluewaters --thornlist=../einsteintoolkit.th | cat >& compilation_trial.out The error on which I am actually stuck is the following: COMPILING arrangements/Carpet/CarpetLib/src/interpolate_3d_2tl.cc /mnt/a/u/sciteam/cipollet/Cactus/arrangements/Carpet/CarpetLib/src/interpolate_3d_2tl.cc:112:48: error: macro "CCTK_LOOP3STROFF_NORMAL" requires 24 arguments, but only 23 given dstipadext, dstjpadext, dstkpadext) { ^ In file included from /mnt/a/u/sciteam/cipollet/Cactus/src/include/cctk_core.h:157:0, from /mnt/a/u/sciteam/cipollet/Cactus/configs/ETK_standard/bindings/include/CarpetLib/cctk.h:7, from /mnt/a/u/sciteam/cipollet/Cactus/arrangements/Carpet/CarpetLib/src/interpolate_3d_2tl.cc:1: /mnt/a/u/sciteam/cipollet/Cactus/arrangements/Carpet/CarpetLib/src/interpolate_3d_2tl.cc: In function 'void CarpetLib::interpolate_3d_2tl(const T*, CCTK_REAL8, const T*, CCTK_REAL8, const ivect3&, const ivect3&, T*, CCTK_REAL8, const ivect3&, const ivect3&, const ibbox3&, const ibbox3&, const ibbox3&, const ibbox3&, void*)': /mnt/a/u/sciteam/cipollet/Cactus/src/include/cctk_Loop.h:2460:3: error: 'CCTK_LOOP3STROFF_NORMAL' was not declared in this scope CCTK_LOOP3STROFF_NORMAL(name, \ ^ /mnt/a/u/sciteam/cipollet/Cactus/src/include/cctk_Loop.h:2444:3: note: in expansion of macro 'CCTK_LOOP3STROFF' CCTK_LOOP3STROFF(name, \ ^ /mnt/a/u/sciteam/cipollet/Cactus/src/include/cctk_Loop.h:2428:3: note: in expansion of macro 'CCTK_LOOP3STR' CCTK_LOOP3STR(name, \ ^ /mnt/a/u/sciteam/cipollet/Cactus/arrangements/Carpet/CarpetLib/src/interpolate_3d_2tl.cc:111:3: note: in expansion of macro 'CCTK_LOOP3' CCTK_LOOP3(interpolate_3d_2tl, i, j, k, 0, 0, 0, regiext, regjext, regkext, ^ In file included from /mnt/a/u/sciteam/cipollet/Cactus/configs/ETK_standard/bindings/include/loopcontrol.h:4:0, from /mnt/a/u/sciteam/cipollet/Cactus/arrangements/Carpet/CarpetLib/src/interpolate_3d_2tl.cc:4: /mnt/a/u/sciteam/cipollet/Cactus/arrangements/Carpet/CarpetLib/src/interpolate_3d_2tl.cc: At global scope: /mnt/a/u/sciteam/cipollet/Cactus/arrangements/Carpet/LoopControl/src/loopcontrol.h:263:3: error: expected declaration before '}' token } \ ^ /mnt/a/u/sciteam/cipollet/Cactus/arrangements/Carpet/LoopControl/src/loopcontrol.h:304:42: note: in expansion of macro 'LC_ENDLOOP3STROFF_NORMAL' #define CCTK_ENDLOOP3STROFF_NORMAL(name) LC_ENDLOOP3STROFF_NORMAL(name) ^ /mnt/a/u/sciteam/cipollet/Cactus/src/include/cctk_Loop.h:2470:3: note: in expansion of macro 'CCTK_ENDLOOP3STROFF_NORMAL' CCTK_ENDLOOP3STROFF_NORMAL(name) \ ^ /mnt/a/u/sciteam/cipollet/Cactus/src/include/cctk_Loop.h:2452:3: note: in expansion of macro 'CCTK_ENDLOOP3STROFF' CCTK_ENDLOOP3STROFF(name) \ ^ /mnt/a/u/sciteam/cipollet/Cactus/src/include/cctk_Loop.h:2436:3: note: in expansion of macro 'CCTK_ENDLOOP3STR' CCTK_ENDLOOP3STR(name) \ ^ /mnt/a/u/sciteam/cipollet/Cactus/arrangements/Carpet/CarpetLib/src/interpolate_3d_2tl.cc:116:3: note: in expansion of macro 'CCTK_ENDLOOP3' CCTK_ENDLOOP3(interpolate_3d_2tl); ^ make[3]: *** [interpolate_3d_2tl.cc.o] Error 1 make[2]: *** [make.checked] Error 2 make[1]: *** [/mnt/a/u/sciteam/cipollet/Cactus/configs/ETK_standard/lib/libthorn_CarpetLib.a] Error 2 make: *** [ETK_standard] Error 2 As you can see, the CarpetLib is not compiled, due to an error on a call to a macro of Cactus. As the CarpetLib is a pretty standard one, I assume that there should be some bugs in the machine configuration file in simfactory, probably when specifying the flags for the compilers. I also tried the other configuration for BW machine (i.e. the "-cray" and "-pgi" versions) when trying to compile another config of the ETK on BW, but neither those where succesful. Can anyone give me some hint? Thank you very much, Federico Cipolletta.
