[Einstein Toolkit] #778: Compiling PittNullCode is slow

#778: Compiling PittNullCode is slow -----------------------------------+---------------------------------------- Reporter: eschnett | Owner: Type: defect | Status: new Priority: major | Milestone: Component: EinsteinToolkit thorn | Version: Keywords: | -----------------------------------+---------------------------------------- Compiling PittNullCode is very slow on some systems (e.g. with gcc). I believe this is because files such as NullConstr_R00.F90 contain many whole-array operations that the compiler has to analyse. I suggest to rewrite these routines, using e.g. forall or do loops. If we want to keep the elegant, index-free notation, then I suggest to add an elemental subroutine for the actual calculations and calling it with whole arrays. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/778> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #1100: Correct backtrace generation in Carpet

#1100: Correct backtrace generation in Carpet ----------------------+----------------------------------------------------- Reporter: eschnett | Owner: eschnett Type: defect | Status: new Priority: major | Milestone: Component: Carpet | Version: Keywords: | ----------------------+----------------------------------------------------- The file backtrace.cc in CarpetLib does not #include <cctk.h>; hence all HAVE_BACKTRACE* macros are undefined, and only basic backtraces are generated. Correcting this is non-trivial, since the backtrace code is arcane, is written in C, probably expects glibc, contains (I'm fairly certain) memory allocation errors, and doesn't build e.g. on Mac OSX. The code also spends an inordinate amount of time allocating and freeing string buffers, which should be replaced by simply using C++ streams. The backtrace code also probably requires a few more autoconf tests, so that it can be disabled where it does not work. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1100> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #914: Don't use fork()

#914: Don't use fork() -----------------------------------+---------------------------------------- Reporter: eschnett | Owner: Type: defect | Status: new Priority: major | Milestone: Component: EinsteinToolkit thorn | Version: Keywords: | -----------------------------------+---------------------------------------- It seems that it is in many cases not safe to call fork() in MPI applications. This page <http://www.open-mpi.de/faq/?category=openfabrics #ofa-fork> has some information. The upshot seems to be: - In many (most) cases, one can call system() or popen() to execute external processes while waiting for them. - It is generally not safe to call fork() to execute a certain task in the background. However, it should be possible to use threads in this case. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/914> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #980: Remove support for the flesh-based MPI mechanism

#980: Remove support for the flesh-based MPI mechanism -------------------------+-------------------------------------------------- Reporter: hinder | Owner: Type: enhancement | Status: new Priority: major | Milestone: Component: Cactus | Version: Keywords: | -------------------------+-------------------------------------------------- The flesh-based MPI mechanism has just been deprecated in favour of ExternalLibraries/MPI. Even though the latter is new, it is probably a good idea to completely disable the old mechanism since having any mixture of thorns/optionlists using the old and new mechanisms is completely untested and will likely lead to problems and confusion. It's better to give a useful fatal error message if someone still specifies "MPI = " in their optionlist than to have things break in other weird and wonderful ways. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/980> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

#64: Refactory/redesign archiving ------------------------+--------------------------------------------------- Reporter: mthomas | Owner: mthomas Type: defect | Status: new Priority: major | Milestone: Component: SimFactory | Version: Keywords: | ------------------------+--------------------------------------------------- Implement archiving using archive machines with an iomethod key. Provide another key like rsync-excludes for people to exclude files from being archived. Provide a lightweight archive-like method for copying a simulation from one machine to another machine. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/64> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #394: Testsuite log file should contain more information

#394: Testsuite log file should contain more information -------------------------+-------------------------------------------------- Reporter: hinder | Owner: Type: enhancement | Status: new Priority: minor | Milestone: Component: Cactus | Version: Keywords: testsuites | -------------------------+-------------------------------------------------- It is useful to look at the testsuite log file for information about how the tests were run. For example, which compiler was used, and with what compiler options. We need to balance this against providing information which will always change, making diffs hard to read. The most extreme case would be to output all make variables. Maybe better would be to output CC, CFLAGS, CXX, etc. Another option would be to parse these and say "intel compiler", "gcc", "pgi" etc. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/394> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit
