[Einstein Toolkit] #1378: provide equivalent of fprintf(stderr, "%s\n", msg) in Fortran

#1378: provide equivalent of fprintf(stderr, "%s\n", msg) in Fortran -------------------------+-------------------------------------------------- Reporter: rhaas | Owner: Type: enhancement | Status: new Priority: minor | Milestone: Component: Cactus | Version: development version Keywords: | -------------------------+-------------------------------------------------- Currently to write out multi-line error messages in Fortran we use multiple calls to CCTK_WARN(1, warnline) followed possibly by a CCTK_ERROR(errline). Each of the level 1 warnings (given certain settings of the Cactus parameters) prints the source file location and other information to screen, thus cluttering the error output. A typical error message might look like this: {{{ WARNING level 1 in thorn GRHydro processor 179 host nid03278 (line 386 of GRHydro_Prim2Con.F90): -> EOS error in prim2con_hot: WARNING level 1 in thorn GRHydro processor 179 host nid03278 (line 388 of GRHydro_Prim2Con.F90): -> 64897 22 37 31 -1.440000E+00 -8.496000E+01 -1.296000E+01 8.595485E+01 WARNING level 1 in thorn GRHydro processor 179 host nid03278 (line 390 of GRHydro_Prim2Con.F90): -> 1.228064E-09 -8.644951E-03 -5.842300E-01 4.789413E-01 WARNING level 1 in thorn GRHydro processor 179 host nid03278 (line 392 of GRHydro_Prim2Con.F90): -> code: 106 WARNING level 1 in thorn GRHydro processor 179 host nid03278 (line 394 of GRHydro_Prim2Con.F90): -> reflevel: 0 WARNING level 1 in thorn GRHydro processor 179 host nid03278 (line 386 of GRHydro_Prim2Con.F90): -> EOS error in prim2con_hot: WARNING level 1 in thorn GRHydro processor 179 host nid03278 (line 388 of GRHydro_Prim2Con.F90): -> 64897 23 37 31 1.440000E+00 -8.496000E+01 -1.296000E+01 8.595485E+01 WARNING level 1 in thorn GRHydro processor 179 host nid03278 (line 390 of GRHydro_Prim2Con.F90): -> 1.227982E-09 -8.644755E-03 -5.798389E-01 4.789407E-01 WARNING level 1 in thorn GRHydro processor 179 host nid03278 (line 392 of GRHydro_Prim2Con.F90): -> code: 106 WARNING level 1 in thorn GRHydro processor 179 host nid03278 (line 394 of GRHydro_Prim2Con.F90): -> reflevel: 0 WARNING level 1 in thorn GRHydro processor 179 host nid03278 (line 166 of GRHydro_Eigenproblem.F90): -> EOS ERROR in eigenvalues_hot WARNING level 1 in thorn GRHydro processor 179 host nid03278 (line 168 of GRHydro_Eigenproblem.F90): -> keyerr: 668 keytemp: 0 WARNING level 0 in thorn GRHydro processor 179 host nid03278 (line 170 of GRHydro_Eigenproblem.F90): -> 1.228064E-09 -8.644951E-03 -5.842300E-01 4.789413E-01 5.668696E-04 cactus_sim: Cactus/arrangements/Carpet/Carpet/src/helpers.cc:314: int Carpet::Abort(const cGH*, int): Assertion `0' failed. Rank 179 with PID 13388 received signal 6 }}} with errors from multiple MPI processes possibly intersecting each other. It would be useful to provide a subroutine equivalent to {{{ subroutine CCTK_WARN_SHORT(msg) character*(*) :: msg write (stderr,'(a)') msg end subroutine }}} (name is up for discussion) that outputs only "msg" to stderr (and the warning listener registered in the flesh) without prepending the file information output. A similar routine might be offered for C (in WARN and VWarn flavors) both for symmetry reasons and to have the message pass the warning listeners, though in C one can usually get away with a single CCTK_VWarn and a very long format string. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1378> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #1473: Carpet segfaults in Shutdown

#1473: Carpet segfaults in Shutdown --------------------+------------------------------------------------------- Reporter: knarf | Owner: eschnett Type: defect | Status: new Priority: minor | Milestone: Component: Carpet | Version: development version Keywords: | --------------------+------------------------------------------------------- For high numbers of threads, Carpet segfaults in Shutdown for the testsuite CarpetWaveToyNewRecover_test_1proc. I tried this with gcc and intel on a Debian system. The machine I run this on (spine, with the default simfactory configurations) has 2 processors with 8 cores, and ht enabled. When I run this testsuite with 1 mpi process but certain numbers of threads (e.g. 9, 11, 16) I see this segfault. Which number triggers the bug seems to depend on the compiler, but seems to be consistent within tries. The backtrace I see is, e.g.,: {{{ 1.

#590: McLachlan should allow other thorns to set the gauge -----------------------------------+---------------------------------------- Reporter: bmundim | Owner: Type: defect | Status: new Priority: major | Milestone: Component: EinsteinToolkit thorn | Version: Keywords: | -----------------------------------+---------------------------------------- The parameters lapse_evolution_method and shift_evolution_method are usually set to ML_BSSN in McLachlan. However they are never checked in the code. McLachlan indeed seems to ignore their values and overwrite whatever the values of lapse or shift set elsewhere, preventing therefore other thorns from setting them differently. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/590> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

The tests had a parameter setting WaveMoL::num_timelevels = 3 which didn't correspond to any WaveMoL parameter, so previously the tests would crash earlier. I removed that parameter setting, and now the tests fail with this "extrapolation in time" error. I don't understand this failure. The times array seems to be non-monotonic [0.4, 0.675, 0.275] perhaps indicating that it might not have been initialised correctly? The coarse grid timestep should be 0.1*0.25 = 0.025, so I don't see where these times come from during iteration 1. The NaNs in the norms are probably poison, which probably wasn't enabled when this test was written, so nobody noticed. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1497> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

This makes it possible to use IOUtils file reader with hydro data. This is somewhat similar to IDFileADM's extension of ADMBase's options, only we do not have to set any grid scalars.

[Einstein Toolkit] #849: Drop explicit support for Fortran 77 in Cactus

#849: Drop explicit support for Fortran 77 in Cactus -------------------------+-------------------------------------------------- Reporter: eschnett | Owner: Type: enhancement | Status: new Priority: minor | Milestone: Component: Cactus | Version: Keywords: | -------------------------+-------------------------------------------------- I suggest to drop explicit support for Fortran 77 in Cactus. Fortran 77 is, for all practical purposes, a subset of Fortran 90, and thus Fortran 77 code can be compiled by Fortran 90 compilers. There is currently no platform that has a Fortran 77 and no Fortran 90 compiler, and there is no Fortran source code in Cactus that cannot be compiled by a Fortran 90 compiler. In a way, supporting Fortran 77 as language is similar to supporting K&R C as a language. We don't do this either. I suggest to remove/ignore all configuration options regarding Fortran 77, and to compile .f77 and .F77 files with a Fortran 90 compiler. This change will simplify the configuration stage of Cactus. I don't expect any user to notice. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/849> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit
