[Einstein Toolkit] #1718: MemSpeed: Re-use allocated memory

#1718: MemSpeed: Re-use allocated memory -----------------------------------+---------------------------------------- Reporter: eschnett | Owner: Type: enhancement | Status: new Priority: minor | Milestone: Component: EinsteinToolkit thorn | Version: development version Keywords: | -----------------------------------+---------------------------------------- Allocating memory is slow. In thorn MemSpeed, we should re-use memory that has been allocated instead of allocating new memory for each benchmark. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1718> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #331: SimFactory does not abort if it has been given a nonexistent optionlist

#331: SimFactory does not abort if it has been given a nonexistent optionlist ------------------------+--------------------------------------------------- Reporter: hinder | Owner: mthomas Type: defect | Status: new Priority: major | Milestone: Component: SimFactory | Version: Keywords: | ------------------------+--------------------------------------------------- If I specify a nonexistent optionlist in a machine's .ini file, I get the warning Info: optionlist is: None Warning: no option list specified, using blank option list This is incorrect. I have specified an optionlist, but it has not been found, which indicates an error. In this case I would expect a fatal error. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/331> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #228: Make it easier for users to create accounts on TRAC

#228: Make it easier for users to create accounts on TRAC ----------------------------------+----------------------------------------- Reporter: hinder | Owner: Type: enhancement | Status: new Priority: major | Milestone: Component: EinsteinToolkit trac | Version: Keywords: | ----------------------------------+----------------------------------------- Currently, in order to interact fully with TRAC, it is necessary to have a CCT account. I would prefer that all potential users of the ET/Cactus TRAC could create accounts. This way, it would be possible for all bug reporters to be notified of changes to the tickets they create, and makes it more likely that they will respond to requests for further information and confirmations of fixes. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/228> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #270: Need web instructions for building on a new machine

#270: Need web instructions for building on a new machine -------------------------------------+-------------------------------------- Reporter: eschnett | Owner: Type: defect | Status: new Priority: major | Milestone: Component: EinsteinToolkit website | Version: Keywords: | -------------------------------------+-------------------------------------- We should have instructions on the web that explain how to build the Einstein Toolkit on a new machine, i.e. a machine for which we don't have a SimFactory entry already. This seems to be a fairly common case for new users, who rather want to build on their own machine instead of on Queen Bee. This should probably concentrate on configuring Cactus first, i.e. on configuring SimFactory for building a configuration. Job submission etc. should come later. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/270> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #1804: Provide an Einstein Toolkit User Guide

#1804: Provide an Einstein Toolkit User Guide -------------------------+-------------------------------------------------- Reporter: hinder | Owner: Type: enhancement | Status: new Priority: minor | Milestone: Component: Other | Version: development version Keywords: | -------------------------+-------------------------------------------------- We currently have documentation for individual thorns, but there is no documentation for the toolkit as a whole, describing how best to accomplish certain tasks. The [http://arxiv.org/abs/1111.3344 Einstein Toolkit paper] is a good starting point, but it is a static document, and is not quite at the level of documentation. I propose to take the paper and convert it into a user guide for the ET. It should not replicate detailed information already available in thorn documentation (rather it should link to it), but should provide a high level overview. It should also contain best practices for working with the ET. This would be the first point of reference for new users of the toolkit. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1804> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #1889: correct finding normalization value for relerr compuation

#1889: correct finding normalization value for relerr compuation --------------------+------------------------------------------------------- Reporter: rhaas | Owner: Type: defect | Status: new Priority: major | Milestone: Component: Cactus | Version: development version Keywords: | --------------------+------------------------------------------------------- Before it would have taken the larger of the abs value of the new and old data of the last data set rather than the largest abs value of the new and old data of all the datasets. This will make relative errros smaller and will be particularly noticeable in cases where the last dataset was small or zero. This should get rid of the "Error, how did I get here" warnings (that really indicated an logic error). -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1889> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #1263: Multipole does not handle variable names correctly

#1263: Multipole does not handle variable names correctly -----------------------------------+---------------------------------------- Reporter: hinder | Owner: Type: defect | Status: new Priority: major | Milestone: Component: EinsteinToolkit thorn | Version: Keywords: Multipole | -----------------------------------+---------------------------------------- When you specify variables for Multipole to decompose, you have the option of giving it a "name" for the variable to be used in the output filename. This is useful if you are decomposing Psi4r, with imaginary part Psi4i, and want the file to just be named "Psi4". If you don't specify a name, it is supposed to use the original variable name. However, at the moment, this last part seems to be broken. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1263> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #1201: Incorrect dtshift in Exact with shift_add_{x, y, z} parameters

#1201: Incorrect dtshift in Exact with shift_add_{x,y,z} parameters -----------------------------------+---------------------------------------- Reporter: barry.wardell | Owner: Type: defect | Status: new Priority: major | Milestone: Component: EinsteinToolkit thorn | Version: Keywords: | -----------------------------------+---------------------------------------- The Exact thorn has shift_add_{x,y,z} parameters for adding a constant to the shift. Considering these as a coordinate transformation using a vector v^i = [shift_add_x, shift_add_y, shift_add_z], such a transformation should affect both the shift and its time derivative. This is because the time derivative in the new coordinates differs from the time derivative in the old coordinates by a term v^j d(beta^i)/dx^j. This is correctly implemented as a 4D coordinate transformation in the EinsteinExact thorns and I have verified that the difference relative to the Exact thorn is given by this missing term. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1201> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit
