[Einstein Toolkit] #1536: Wrong code in Piraha.hpp

#1536: Wrong code in Piraha.hpp ----------------------+----------------------------------------------------- Reporter: eschnett | Owner: Type: defect | Status: new Priority: critical | Milestone: Component: Cactus | Version: development version Keywords: | ----------------------+----------------------------------------------------- Piraha.hpp contains in lines 171 ff the code {{{ const char c; Literal(char b) : c(b) {} bool match(Matcher *m); std::string fmt() { std::string s = "literal("; s += c+")"; return s; } }}} In this code, the expression c+")" adds a character to a pointer, in effect adding to the pointer. This does not append to the string s, as was intended. There seem to be several similar cases in other locations as well. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1536> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #1568: Reduce overhead of Formaline

#1568: Reduce overhead of Formaline -------------------------+-------------------------------------------------- Reporter: hinder | Owner: Type: enhancement | Status: new Priority: major | Milestone: Component: Cactus | Version: development version Keywords: | -------------------------+-------------------------------------------------- The Formaline thorn, used for storing important information about a simulation in the simulation output, currently has some performance and size overheads which discourage people from using it. These should be reduced or mitigated to encourage people to use this important thorn. This ticket is based on discussion in #1565. Problems with Formaline: * During compilation, Formaline stores the built source tree in a cactusjar.git repository. My impression is that this takes a lot of time on slow filesystems. * During compilation, Formaline stores the whole source tree as tarballs in the executable. My impression is that this is also slow. * The source tarballs output in the simulation output directory are often many times larger than the rest of the simulation, and cause a lot of overhead when transferring simulations for analysis. This might be improved by a better sync tool (simfactory 3?) which identified that tarballs were identical to those which have already been transferred, and skipped the transfer. I would like that the source tarballs are identical if the contents are identical, even if Cactus has been rebuilt. I think I observed that this was not the case (maybe a build ID is included?). * As an aside: there is a message at link time that Formaline has finished doing something, but this is misleading; Formaline has other tasks which it does after this message is displayed; the wait for the final executable is not due solely to linking, but also to some archiving task of formaline. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1568> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

#1566: Update Cactus autoconf ----------------------+----------------------------------------------------- Reporter: eschnett | Owner: Type: defect | Status: new Priority: major | Milestone: Component: Cactus | Version: development version Keywords: | ----------------------+----------------------------------------------------- We are using autoconf 2.13 for Cactus. This release is by now 15 years old and doesn't support Fortran (nor modern C++ features). It is time to update. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1566> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #1557: include thorn TestMoL in ET

#1557: include thorn TestMoL in ET -----------------------------------+---------------------------------------- Reporter: rhaas | Owner: Type: enhancement | Status: new Priority: optional | Milestone: Component: EinsteinToolkit thorn | Version: development version Keywords: MoL | -----------------------------------+---------------------------------------- the thorn TestMoL (for the CactusTest arrangment) exercises most of MoL's integrators (not the Adams-Bashforth ones yet nor the generic one since they are "different"). It would be useful to include in the ET to have a basic test of the central ODE solver. The thorn is currently in incoming {{{ svn co https://svn.einsteintoolkit.org/incoming/TestMoL }}} it contains test cases (that's the whole point) and some documentation. I have used it to test the recent MoL commits and found two outstanding bugs that way. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1557> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #1561: Show paths relative to CCTK_HOME in non-verbose output

#1561: Show paths relative to CCTK_HOME in non-verbose output ---------------------------+------------------------------------------------ Reporter: barry.wardell | Owner: Type: enhancement | Status: new Priority: major | Milestone: Component: Cactus | Version: development version Keywords: | ---------------------------+------------------------------------------------ When Cactus is compiling a thorn, it currently prints the absolute path to the file being compiled. This can lead to very long output lines. I suggest instead printing just the path relative to CCTK_HOME. The attached patch implements this, but only when in non-verbose mode. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1561> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #1505: remove the MoL number of variables accumulators

#1505: remove the MoL number of variables accumulators -----------------------------------+---------------------------------------- Reporter: rhaas | Owner: Type: enhancement | Status: new Priority: optional | Milestone: Component: EinsteinToolkit thorn | Version: development version Keywords: MoL | -----------------------------------+---------------------------------------- The attached patches removes the need for MoL's accumulator parameters to count the number of evolved, constrained and save-and-restore variables. Instead it counts them during MoL_RegisterVariables and using timelevels as a way of creating new variable storage for the scratch levels. This means unfortunately that it will create C pointers for 99 (the current max in interface.ccl) scratch timelevels ie there is ScratchSpace_p_p_p_p..._p . Currently applies on top of trunk. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1505> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit
