[Einstein Toolkit] #1465: Boost doesn't honor parallel build options

#1465: Boost doesn't honor parallel build options -----------------------------------+---------------------------------------- Reporter: knarf | Owner: Type: enhancement | Status: new Priority: minor | Milestone: Component: EinsteinToolkit thorn | Version: development version Keywords: | -----------------------------------+---------------------------------------- ExternalLibraries/Boost doesn't honor parallel build options. This is because it doesn't use 'make' to build, but a tool called 'b2', which isn't using 'make's environment variables, nor is it capable to interact with the jobserver make provides. Manually parsing MAKEFLAGS inside the configure script of the thorn also doesn't work, as this doesn't contain the requested number of jobs, but only the fact that a parallel build was requested and a pointer to the jobserver. Manually interacting with this job server might be possible for gnu make, but is probably messy and highly likely not portable. However, building a huge package like Boost in parallel is something we have to achieve. On my workstation it reduces the time used for building Boost alone from about 500s to 60s. The only alternative that is easy enough to implement that I can see right now is to make it possible to pass a number of processes used for building to Cactus (in addition to passing it to make), and Boost using this variable for the parallel build. Simfactory should then also pass this to Cactus. One downside of this would be that if multiple libraries were to be built in parallel you might end up using almost twice as many jobs than specified. On the other hand, this doesn't seem to be the case right now and even if using twice as many might be better than many times too few. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1465> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #1314: increase number of triggers in AEIThorns trigger

#1314: increase number of triggers in AEIThorns trigger -----------------------------------+---------------------------------------- Reporter: rhaas | Owner: Type: enhancement | Status: new Priority: minor | Milestone: Component: EinsteinToolkit thorn | Version: Keywords: Trigger | -----------------------------------+---------------------------------------- currently the max is 10. I find myself needing more (15 to be precise). Can we increase this number to say 39 (or some other largish non-typical number) or are that many parameters too expensive to support? Similarly (but more complicated) it would be useful to be able to steer more than one parameter/grid scalar when a trigger triggers. The current way of specifying targets is unfortunately not well suited for this. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1314> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #1117: Wrong CarpetIOASCII headers for complex 2D output.

#1117: Wrong CarpetIOASCII headers for complex 2D output. ----------------------------------------+----------------------------------- Reporter: reisswig@… | Type: defect Status: new | Priority: minor Milestone: | Component: Other Version: | Keywords: ----------------------------------------+----------------------------------- I am outputting a 2d _complex_ array (called "extracted_vars") using 2d CarpetIOASCII output. Using the standard output format, the data starts at column 13. So the first array element "extracted_vars[0]" is at column 13. Now, since I have a complex array, the second element, "extracted_vars[1]", must be at column 15 (column 14 contains the imaginary part of element [0]). In older versions of Carpet, this was reported correctly in the header. In the current version, it is incorrect. The second element, "extracted_vars[1]" is reported to be in column 14 instead of 15. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1117> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

#542: Remove thorn CactusArchive/ADM from thorn list -----------------------------------+---------------------------------------- Reporter: eschnett | Owner: Type: task | Status: new Priority: major | Milestone: Component: EinsteinToolkit thorn | Version: Keywords: | -----------------------------------+---------------------------------------- Remove thorn CactusArchive/ADM from thorn list. This thorn is outdated, and we should updated out test cases instead. It also takes a long time and a lot of memory to compile. If we want an ADM formulation (which is doubtful since we don't use it ourselves), we should implement one via Kranc. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/542> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #1381: Carpet no longer has an implied sync() call after restriction

#1381: Carpet no longer has an implied sync() call after restriction --------------------+------------------------------------------------------- Reporter: rhaas | Owner: eschnett Type: defect | Status: new Priority: minor | Milestone: Component: Carpet | Version: development version Keywords: | --------------------+------------------------------------------------------- I just pushed two tests for the higher order restriction code into CarpetProlongateTest. What I did was to generate the test data before the commit that removes the extra sync, then save the data and apply as the test data on top of the master branch. I also verified that indeed I get the same restricted data across an interprocessor boundary (ie in the z direction of the tests). Surprisingly I actually do since in fact the schedule.ccl file in CarpetProlongateTest does not apply boundary conditions are SYNC in MoL_PostStep so that I should have gotten test failures. This would seem to indicate that either (a) I don't have my test setup correctly (always possibly) or (b) there is yet another SYNC hidden somewhere inside of CarpetLib/Carpet. On the other hand, the current "_rest" tests in CarpetProlongateTest now fail for me unless I re-add the sync. Adding a dummy routine and SYNC to MoL_PostStep which I think is the correct thing to do does not help possibly because the SYNC implies a prolongation while a low-level sync call does not (and which is where I see differences). This of course would argue against (b) above. Attached please find my code change a a plot of diffference.z.asc for test_cc_rest_o3 before and after the change. I do not necessarily think that this is a bug, it certainly is unexpected though. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1381> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #1363: Crash on startup in Piraha

#1363: Crash on startup in Piraha ----------------------+----------------------------------------------------- Reporter: eschnett | Owner: Type: defect | Status: new Priority: blocker | Milestone: ET_2013_05 Component: Other | Version: Keywords: | ----------------------+----------------------------------------------------- I built a Cactus configuration with fewer thorns than usual, and with assertions disabled (-DNDEBUG. This configuration does not start; it crashes on startup with a backtrace {{{ #0 std::_Rb_tree<void*, void*, std::_Identity<void*>, std::less<void*>, std::allocator<void*> >::_M_insert_unique<void* const&> (this=0x0, __v=@0x7fff5fbfd228) at locale_facets.h:1078 #1 0x000000010072e6f2 in smart_ptr<piraha::Grammar>::smart_ptr (this=0x104b9d0d0, ptr=0x10570a5a0, array_=<value temporarily unavailable, due to optimizations>) at stl_set.h:415 #2 0x0000000100721542 in piraha::AutoGrammar::reparserGenerator () at AutoGrammar.cc:6 #3 0x0000000100c2ada6 in _GLOBAL__sub_I_Grammar.cc () at smart_ptr.hpp:53 #4 0x00007fff5fc13762 in __dyld__ZN16ImageLoaderMachO16doInitializationERKN11ImageLoader11LinkContextE () }}} This indicates that the failure oocurs during initialisation of a global variable during startup. _Rb_tree points to a set or a map. This may be caused by {{{ extern smart_ptr<Grammar> pegGrammar; }}} I also see that Piraha has some code in smart_ptr.hpp that is only added when DNEBUG is defined, and contains assert calls (!). Given that NDEBUG disables assert, this looks like an error. It is considered bad style to use C++ constructors to initialise global variables; this is fragile and breaks often. I suggest instead to change these global variables to pointers, to initialise them to NULL, and to allocate to respective objects explicitly at run time. This is safer, as it ensures that things are allocated in the right order. I also just see that there is a global variables called "ptrs" in Piraha. This is not good; please use a cctki_ prefix for all globally visible variables and functions (or move them into a namespace). -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1363> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit
