[Einstein Toolkit] #670: commit 166d77a440a5 and b5f8b4ff16fb does not compile with gfortran

#670: commit 166d77a440a5 and b5f8b4ff16fb does not compile with gfortran --------------------+------------------------------------------------------- Reporter: rhaas | Owner: eschnett Type: defect | Status: new Priority: major | Milestone: Component: Carpet | Version: Keywords: | --------------------+------------------------------------------------------- I get the following error messages (the second commit changes make.code.defn to activate code from the first commit): {{{ In file /home/rhaas/ET/configs/et/build/Carpet/LoadBalanceReal/carpet_region.f90:59 type(superregion2), pointer, intent(out) :: sregion 1 Error: POINTER attribute conflicts with INTENT attribute at (1) }}} this happens with gfortran 4.2 on a red hat 5.7 system (eg. the cct machines or my workstation at Caltech or (former workstation at) GT). I attach the full make output (with many more errors). Looking at the fortran code it states that: {{{ ! Note that using intent on pointer arguments requires fortran 2003. ! It is not allowed in fortran 90 or 95. }}} I tried setting std=f2003 in gfortran (see make.log) but apparently this is not sufficient for gfortran 4.1.2 I am not which other fortran compilers are affected. If we keep this then we will have to make very clear all user realise that Carpet requires Fortran 2003 and a fairly new gfortran compiler (or intel) not just Fortran 90. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/670> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

#495: MPI error from Carpet with QuasiLocalMeasures: "MPI_SUM is not defined for non-intrinsic datatypes" --------------------+------------------------------------------------------- Reporter: hinder | Owner: eschnett Type: defect | Status: new Priority: major | Milestone: Component: Carpet | Version: Keywords: | --------------------+------------------------------------------------------- In the development (Mercurial) version of Carpet, but not the stable (Git) version, QuasiLocalMeasures fails with the following error message: ... INFO (QuasiLocalMeasures): Landau-Lifshitz angular momentum x: 0.00000 INFO (QuasiLocalMeasures): Landau-Lifshitz angular momentum y: 0.00000 INFO (QuasiLocalMeasures): Landau-Lifshitz angular momentum z: 0.00000 [sl-18:26396] *** An error occurred in MPI_Reduce: the reduction operation MPI_SUM is not defined for non-intrinsic datatypes [sl-18:26396] *** on communicator MPI COMMUNICATOR 3 SPLIT FROM 0 [sl-18:26396] *** MPI_ERR_OP: invalid reduce operation [sl-18:26396] *** MPI_ERRORS_ARE_FATAL (your MPI job will now abort) This affects the QuasiLocalMeasures test suite, but was also reported and discussed on the ET mailing list: http://lists.einsteintoolkit.org/pipermail/users/2011-May/001107.html Additional debugging was suggested to try to locate the reason for the error. (Reporting against Carpet even though it might be a problem in QuasiLocalMeasures because it works in the stable Carpet and this will be a possible blocker for promoting the development Carpet to stable). -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/495> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #145: EOS_Omni requires HDF5 library. What about if it only uses HDF5 instead?

#145: EOS_Omni requires HDF5 library. What about if it only uses HDF5 instead? ---------------------------+------------------------------------------------ Reporter: bmundim | Owner: Type: enhancement | Status: new Priority: major | Milestone: Component: Other | Version: Keywords: EOS_Omni HDF5 | ---------------------------+------------------------------------------------ At the moment EOS_Omni requires the HDF5 library to read the nuclear EOS values from a table. Since not all distros have fortran support for the HDF5 library as a default, I propose to change this requirement and provide a fall back in case this support is not present. Perhaps not using the nuclear EOS, or reading from an ASCII file instead. This could be just a temporary solution until the HDF5 library build script becomes more robust. Opinions? Thanks, Bruno. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/145> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #627: add coordinates of minimum and maximum in reduction operators

#627: add coordinates of minimum and maximum in reduction operators ------------------------------------------------+--------------------------- Reporter: bruno.giacomazzo@… | Type: enhancement Status: new | Priority: major Milestone: | Component: Cactus Version: | Keywords: ------------------------------------------------+--------------------------- In several cases it would be useful for some quantities to know not only their maximum (minimum), but also the (x,y,z) coordinates of the position of their maximum (minimum). Is it possible to modify the reduction operators so that the maximum/minimum can return also the position on the grid of the maximum/minimum of a quantity? According to the Cactus manuals this does not seem possible now. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/627> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #365: ADMBase: evolving with evolution_method="static" does not apply boundary conditions

#365: ADMBase: evolving with evolution_method="static" does not apply boundary conditions ----------------------+----------------------------------------------------- Reporter: eschnett | Owner: Type: defect | Status: new Priority: major | Milestone: Component: Cactus | Version: Keywords: | ----------------------+----------------------------------------------------- When one uses the evolution method ADMBASE::evolution_method = "static" (which is very tempting e.g. for Cowling), then no boundary conditions are applied. This means that the ADMBase variables remain unset on the boundaries after regridding, leading to all sorts of (rather unexpected) problems. The easy solution is to use thorn Exact instead, which applies an exact solution at each time step, including on the boundary. I suggest to remove the ADMBase functionality to provide a "static" evolution method, since this evolution method does not know which boundary condition to apply, and hence is bound to fail in non-trivial situations. Alternatively, ADMBase needs to synchronise in postregrid (and probably a few other bins as well). ADMBase should then also offer to apply an outer boundary condition, in this case probably a Minkowski Dirichlet boundary condition or a von Neumann condition. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/365> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit
