[Einstein Toolkit] #2008: NaNs when running static tov on >40 cores

#2008: NaNs when running static tov on >40 cores -----------------------------------+---------------------------------------- Reporter: allgwy001@… | Owner: Type: defect | Status: new Priority: unset | Milestone: Component: Other | Version: ET_2016_05 Keywords: | -----------------------------------+---------------------------------------- I've been trying to run the static tov example parameter file on an HPC cluster using >40 cores, but this results in NaNs in the data. I can't remember whether the issue first appears at 40 or 41 cores (and won't be able to check this for the next few days), but using 41+ cores definitely gives me NaNs. I remember testing with 39 cores and several other lower values (down to 4), but these runs all seemed fine. So far, I've been able to run larger simulations (e.g. BBHs) on more than 40 cores (same cluster) without any apparent issues. I'll attach the static tov parameter file I used (I think I changed one or two outdated parameters), as well as the PBS script and error/output files from a static tov run on 44 cores. The static tov runs were intended for speed test purposes. The results of the speed tests I've run so far (on fewer than 40 cores) seem quite strange to me, so I'm going to attach a text file with walltimes and CPU times for these runs, too. Any comments would be appreciated! -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/2008> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #1263: Multipole does not handle variable names correctly

#1263: Multipole does not handle variable names correctly -----------------------------------+---------------------------------------- Reporter: hinder | Owner: Type: defect | Status: new Priority: major | Milestone: Component: EinsteinToolkit thorn | Version: Keywords: Multipole | -----------------------------------+---------------------------------------- When you specify variables for Multipole to decompose, you have the option of giving it a "name" for the variable to be used in the output filename. This is useful if you are decomposing Psi4r, with imaginary part Psi4i, and want the file to just be named "Psi4". If you don't specify a name, it is supposed to use the original variable name. However, at the moment, this last part seems to be broken. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1263> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #1201: Incorrect dtshift in Exact with shift_add_{x, y, z} parameters

#1201: Incorrect dtshift in Exact with shift_add_{x,y,z} parameters -----------------------------------+---------------------------------------- Reporter: barry.wardell | Owner: Type: defect | Status: new Priority: major | Milestone: Component: EinsteinToolkit thorn | Version: Keywords: | -----------------------------------+---------------------------------------- The Exact thorn has shift_add_{x,y,z} parameters for adding a constant to the shift. Considering these as a coordinate transformation using a vector v^i = [shift_add_x, shift_add_y, shift_add_z], such a transformation should affect both the shift and its time derivative. This is because the time derivative in the new coordinates differs from the time derivative in the old coordinates by a term v^j d(beta^i)/dx^j. This is correctly implemented as a 4D coordinate transformation in the EinsteinExact thorns and I have verified that the difference relative to the Exact thorn is given by this missing term. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1201> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

#1690: The test system should treat a nonzero exit code from Cactus as a failure --------------------+------------------------------------------------------- Reporter: hinder | Owner: Type: defect | Status: new Priority: minor | Milestone: Component: Cactus | Version: development version Keywords: | --------------------+------------------------------------------------------- The test system seems to ignore the fact that Cactus exits with a nonzero exit code. It displays Cactus exited with error code 1 Please check the logfile... No files created in test directory Success: 0 files identical And in the summary at the end, it treats this as a passing test. In this case, there were no test reference files and no files output, because the test (by design) does not produce any data, it just aborts if the test fails. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1690> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit
