bug in Dissipation thorn?
by Kentaro Takami 07 Mar '13

07 Mar '13

Dear all, I encountered the problem in which the simulation result is randomly different at each run( of course I used same executable, par file, HPC and so on.). Finally I'm doubting the origin of the problem is "CactusNumerical/Dissipation", because when I don't activate this thorn, the problem can be disappeared. In this thorn, "dissipation.c" calls the fortran subroutine "apply_dissipation.F77" directly without scheduling in CACTUS. I guess the variables between C and fortran become inconsistency in this stage. What do you think? I don't have much knowledge to call fortran subroutine from directly c language. So I need comments from expert. Kentaro TAKAMI

New thorn PeriodicCarpet
by Erik Schnetter 03 Mar '13

03 Mar '13

We just added a new thorn PeriodicCarpet to the Einstein Toolkit. Unsurprisingly, this thorn provides periodic boundary conditions for simulations that use Carpet. PeriodicCarpet is implemented using Carpet's communication infrastructure, and is thus significantly more flexible and efficient than the existing thorn Periodic. In particular, simulations with irregular grid structures or with refined regions near or crossing the periodic boundaries will benefit from PeriodicCarpet. -erik -- Erik Schnetter <schnetter(a)cct.lsu.edu> http://www.perimeterinstitute.ca/personal/eschnetter/

Einstein Toolkit Meeting Reminder
by Frank Loeffler 02 Mar '13

02 Mar '13

Hi Please consider joining the weekly Einstein Toolkit phone call at 10 am US central time on Mondays. As usual, you can find instructions how to join on the following web site: http://einsteintoolkit.org/community/support/ In short: the number is (+1) 225-578-4942 or (+1) 866-573-0359 and the conference id is 118682#. Current status: - Trunk has three failing testsuites. - Two because of an issue with the parameter file parser (not parsing 'inf' in 'trunc(atan(-inf))' (do we need that anyway?) - One in the thorn (PeriodicCarpet), which was just added Please make any efforts to fix these problems - Tickets that have been closed last week: - IOUtil::out_dir now defaults to "$parfile" - There are versions of CCTK_WARN that never return (and let the compiler know about that fact) - PeriodicCarpet was added to the ET - XARGS can be used as configuration variable to specify the location of a suitable xargs installation (only found to be necessary on one specific machine: pandora at LSU) - hdf5 index files for checkpoints will now be deleted along with their checkpoints (if this option is used) - There was an issue with simulations not restarting correctly by simfactory if the latter was updated in the meantime. This has been fixed. - 9 Tickets are pending review at the moment. Please take a few minutes of your time to see if you could help reviewing one of these proposed fixes/improvements. [1] - I suppose a lot of people on this list will go to the APS meeting in April. The talk notifications had been sent a while ago and the early bird registration deadline is in the past. While I am sure we all will be quite busy those days it would nevertheless be nice to get most of us together one evening for dinner. This does not have to be (and hopefully isn't, at least not too much) about work. Leave your laptop, but bring some stories to share. Would there be interest in such an evening? As always, please feel free to ask any question somehow related to the toolkit. Frank Loeffler [1] https://trac.einsteintoolkit.org/query?status=review&col=id&col=summary&col…

Developer workshop summer 2013
by Frank Loeffler 02 Mar '13

02 Mar '13

Hi, As most of the developers probably know, there will be a developer meeting after the new-users "day", starting Saturday, Jul 27th. There seems to be consensus that this should at least last until Sunday, but it was not clear yet if the following Monday (Jul 29th) should be included as well. Please express your opinion in the following poll. http://doodle.com/ngyb3pyhfcg36b3v Frank Loeffler

CarpetIOHDF5::output_index = "yes" by default?
by Frank Loeffler 28 Feb '13

28 Feb '13

Hi, Would somebody object to making CarpetIOHDF5::output_index = "yes" the default? (It is currently "no".) It should not hurt to create these small files. (Or, does it?) Frank

Build system bug
by Steven R. Brandt 27 Feb '13

27 Feb '13

I use the CACTUS_CONFIGS_DIR feature regularly, and with newer ET checkouts it seems to call problems. Something is issuing a find in the configs dir and not checking the variable. Anybody know where this is?

McLachlan crash

Hello all, as mentioned earlier in the ET phone call, i have attached the par file used in the run... i tried checking for the nans in the output, but the last hdf5 output was too many iterations earlier and they aren't visible in 1D ascii output either as said, the puncture tracker actually aborted the run, not the nan checker... the last lines of the simulation log look like this: INFO (AHFinderDirect): proc 0: searching for horizon 1/1 INFO (AHFinderDirect): AH 1/1: r=0.888981 at (-0.010571,0.042863,0.000000) INFO (AHFinderDirect): AH 1/1: area=37.24715073 m_irreducible=0.8608185171 71872 449.200 | 0.3696424 0.9877759 | 8.7614309 | 1.847988e+05 | 1.489620e-12 0.0001394 | 7.655611e-18 0.0000003 71876 449.225 | 0.3696349 1.0105778 | 8.7608144 | 1.848221e+05 | -0.0000005 0.0001395 | -1.183581e-09 0.0000003 INFO (Refluxing): Refluxing at iteration 71880 on level 3 of 5 INFO (Refluxing): Refluxing on level 3: INFO (Refluxing): Refluxing at iteration 71880 on level 4 of 5 71880 449.250 | 0.3696287 1.9741189 | 8.7609976 | 1.848285e+05 | -0.0000006 0.0001395 | -2.225731e-09 0.0000003 71884 449.275 | 0.3366873 4.239172e+39 | 8.7611688 | 1.848352e+05 | -0.0000003 0.0001395 | -8.130017e-10 0.0000003 INFO (Refluxing): Refluxing at iteration 71888 on level 2 of 5 INFO (Refluxing): Refluxing on level 2: INFO (Refluxing): Refluxing at iteration 71888 on level 3 of 5 INFO (Refluxing): Refluxing on level 3: INFO (Refluxing): Refluxing at iteration 71888 on level 4 of 5 71888 449.300 | 0.0000000 1.130446e+40 | 8.7613044 | 1.848426e+05 | 1.457866e-12 0.0001395 | 7.432056e-18 0.0000003 71892 449.325 | -0.2467648 8.478344e+39 | 8.7609892 | 1.848595e+05 | -0.0000030 0.0001395 | -4.615484e-09 0.0000003 INFO (Refluxing): Refluxing at iteration 71896 on level 3 of 5 INFO (Refluxing): Refluxing on level 3: INFO (Refluxing): Refluxing at iteration 71896 on level 4 of 5 71896 449.350 | 0.0000000 1.599816e+26 | 8.7611584 | 1.848662e+05 | -0.0000037 0.0001395 | -6.024551e-09 0.0000003 71900 449.375 | -1.413057e+39 1.199862e+26 | 8.7613031 | 1.848734e+05 | -0.0000022 0.0001395 | -4.227202e-09 0.0000003 INFO (Refluxing): Refluxing at iteration 71904 on level 1 of 5 INFO (Refluxing): Refluxing on level 1: INFO (Refluxing): Refluxing on level 1 map 0 component 0 direction 0 face 0: [31,31,3]:[31,32,30] INFO (Refluxing): Refluxing on level 1 map 0 component 0 direction 1 face 0: [31,31,3]:[33,31,30] INFO (Refluxing): Refluxing on level 1 map 0 component 0 direction 2 face 0: [31,31,3]:[33,32,3] INFO (Refluxing): Refluxing at iteration 71904 on level 2 of 5 INFO (Refluxing): Refluxing on level 2: INFO (Refluxing): Refluxing at iteration 71904 on level 3 of 5 INFO (Refluxing): Refluxing on level 3: INFO (Refluxing): Refluxing at iteration 71904 on level 4 of 5 71904 449.400 | 0.0000000 0.9877757 | 8.7613184 | 1.848834e+05 | 1.468319e-12 0.0001395 | 7.506929e-18 0.0000003 71908 449.425 | -1.999770e+25 0.9877756 | 8.7605818 | 1.849092e+05 | -0.0000001 0.0001395 | -7.816558e-11 0.0000003 INFO (Refluxing): Refluxing at iteration 71912 on level 3 of 5 INFO (Refluxing): Refluxing on level 3: INFO (Refluxing): Refluxing at iteration 71912 on level 4 of 5 71912 449.450 | -0.1092106 0.9877756 | 8.7604068 | 1.849231e+05 | -0.0000001 0.0001395 | -9.198894e-11 0.0000003 71916 449.475 | -0.1107971 0.9877756 | 8.7603118 | 1.849354e+05 | -0.0000000 0.0001396 | -4.147005e-11 0.0000003 WARNING level 0 in thorn PunctureTracker processor 0 host vives.uv.es (line 224 of /usus/va/vasme/cactus/ET_2012_11/Cactus/configs/ET_TORI_opt/build/PunctureTracker/puncture_tracker.c): -> Shift at puncture #0 is (-nan,-nan,-nan).

hwloc
by Steven R. Brandt 27 Feb '13

27 Feb '13

I'm obviously doing something wrong. What is it? I have hwloc and hwloc-devel installed. I see no messages about missing headers.
