#215: Driscoll&Healy integration for Multipole -------------------------+-------------------------------------------------- Reporter: eschnett | Owner: Type: enhancement | Status: new Priority: major | Milestone: Component: Cactus | Version: Keywords: | -------------------------+-------------------------------------------------- The attached patch implements a more accurate integration over the sphere, using an algorithm by Driscoll & Healy. This algorithm uses Gaussian integration weights, leading (almost) to exponential convergence. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/215> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #515: Silently overrides DEBUG and OPTIMISE options

#515: Silently overrides DEBUG and OPTIMISE options ---------------------------+------------------------------------------------ Reporter: barry.wardell | Owner: eschnett Type: defect | Status: new Priority: major | Milestone: Component: SimFactory | Version: Keywords: | ---------------------------+------------------------------------------------ When building a configuration with SimFactory, no matter what is set in the OptionList it sets the DEBUG and OPTIMISE options based on its own --optimise and --debug options, which default to enabling optimisation and disabling debug. This means that even if I have an OptionList with DEBUG="yes", SimFactory will silently change this to DEBUG="no". This is very unexpected and should not happen. I think SimFactory should respect what is set in the OptionList and never change it. The attached patch disables the overriding of all OptionList settings. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/515> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #936: Cactus binary tree implementation in src/util/BinaryTree.c is broken

#936: Cactus binary tree implementation in src/util/BinaryTree.c is broken ----------------------+----------------------------------------------------- Reporter: rhaas | Owner: Type: defect | Status: new Priority: optional | Milestone: Component: Cactus | Version: Keywords: | ----------------------+----------------------------------------------------- It contains an obvious bug of the form: {{{ int i = something; if(i<0) {...} else if(i>0) {...} else if(i==0} {...} else {do something else} }}} which is clearly nonsensical (this is the second half of the patch). It also triggers segfaults since it blindly recurses into NULL pointers. The second one concerns adding elements into the tree, which always compares to the prospective subtree's parent rather than the subtree itself. No thorn seems to use these functions right now, nor are they documented. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/936> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #952: OpenCL detection

#952: OpenCL detection -----------------------------------+---------------------------------------- Reporter: knarf | Owner: Type: defect | Status: new Priority: minor | Milestone: ET_2012_11 Component: EinsteinToolkit thorn | Version: development version Keywords: | -----------------------------------+---------------------------------------- OpenCL (the externallibraries thorn) so far only contains some pretty hard-coded logic for Mac installations and also now breaks (aborts) if OpenCL is compiled, but OPENCL_DIR was not set. Before, this was not necessary if opencl was installed in a standard location like /usr. The attached new file (OpenCL.sh - a patch doesn't make sense because it's almost a new file) implements a mechanism similar to other external libraries, but keeps the hard-coded Mac paths since they don't seem to follow any standard convention and I don't have any way to test that. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/952> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #956: Allow skipping setting the RHS to zero in MoL
by Einstein Toolkit 13 Jun '12

#956: Allow skipping setting the RHS to zero in MoL -----------------------------------+---------------------------------------- Reporter: eschnett | Owner: Type: enhancement | Status: new Priority: minor | Milestone: Component: EinsteinToolkit thorn | Version: Keywords: | -----------------------------------+---------------------------------------- By default, MoL initialises the RHS variables to zero before calling the CalcRHS routines. This is (a) superfluous in a well-written code, and (b) makes it impossible to re-use a RHS that has been calculated ahead of time, e.g. at the end of the previous time step. This patch adds a parameter to disable this behaviour. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/956> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #888: Add thorn ExternalLibraries/hwloc to Einstein Toolkit

#888: Add thorn ExternalLibraries/hwloc to Einstein Toolkit -----------------------------------+---------------------------------------- Reporter: eschnett | Owner: Type: enhancement | Status: new Priority: minor | Milestone: ET_2012_05 Component: EinsteinToolkit thorn | Version: Keywords: | -----------------------------------+---------------------------------------- The Portable Hardware Locality (hwloc) software package provides a portable abstraction (across OS, versions, architectures, ...) of the hierarchical topology of modern architectures, including NUMA memory nodes, sockets, shared caches, cores and simultaneous multithreading. It also gathers various system attributes such as cache and memory information. It primarily aims at helping applications with gathering information about modern computing hardware so as to exploit it accordingly and efficiently. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/888> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #951: Add lssh field to cGroupDynamicData
by Einstein Toolkit 11 Jun '12

11 Jun '12

#951: Add lssh field to cGroupDynamicData -------------------------+-------------------------------------------------- Reporter: eschnett | Owner: Type: enhancement | Status: new Priority: major | Milestone: Component: Cactus | Version: Keywords: | -------------------------+-------------------------------------------------- The size and memory layout of grid functions is described by two variables, cctk_lsh and cctk_lssh. The structure cGroupDynamicData is missing the lssh field. I propose to add it, and am providing a patch. cctk_lssh is originally intended to support staggered grid functions, i.e. grid functions that have fewer "active" grid points than are allocated in memory (e.g. n-1 cells vs. n vertices). This can also be used to pad grid variables, which can improve cache efficiency and vectorisation. Fully supporting cctk_lssh in the flesh will later allow supporting padding in Carpet and/or PUGH. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/951> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit
