#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] #502: SimFactory user-guide should be available and updated automatically

#502: SimFactory user-guide should be available and updated automatically -------------------------+-------------------------------------------------- Reporter: hinder | Owner: knarf Type: enhancement | Status: new Priority: major | Milestone: Component: SimFactory | Version: Keywords: | -------------------------+-------------------------------------------------- SimFactory has an incomplete user guide in the doc/userguide directory. This is developed using Sphinx, which is a Python framework for writing documentation. You need to install sphinx to generate this documentation. This can be done using something similar to the following: export PYTHONPATH=/home/ianhin/software/python export PATH=/home/ianhin/software/python/:$PATH hash -r easy_install --install-dir ~/software/python sphinx Then go into the simfactory/doc/userguide directory and type: ./autogen make html to generate HTML documentation (type just "make" to see the other possible targets like PDF etc). This should be regenerated on any commit to the SimFactory/doc/userguide directory and copied to a web-accessible location for inclusion on simfactory.org. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/502> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

#719: Mailing lists could have a link to the archived version of the message -------------------------+-------------------------------------------------- Reporter: hinder | Owner: Type: enhancement | Status: new Priority: minor | Milestone: Component: Other | Version: Keywords: | -------------------------+-------------------------------------------------- It would be useful for the footer of a mailing list posting to contain a URL to the archived version of the message so that it is easy to point people to the message in an email. This would apply to both the Cactus and the ET lists. It appears that this is not straightforward in MailMan 2, but is expected in version 3: http://mail.python.org/pipermail/mailman- users/2011-October/072378.html. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/719> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

#68: GetComponents hang due to certificate issues. --------------------------------+------------------------------------------- Reporter: diener@… | Owner: eric9 Type: defect | Status: new Priority: major | Milestone: Component: GetComponents | Version: ET_2010_06 Keywords: | --------------------------------+------------------------------------------- I did a complete new checkout of the EinsteinToolkit on numrel06 using the version of GetComponents available on the EinsteinToolkit web pages and had GetComponents hang with no errors or warnings when checking out AEIThorns/AEILocalInterp. Trying the checkout manually I got: Error validating server certificate for 'https://svn.aei.mpg.de:443': - The certificate is not issued by a trusted authority. Use the fingerprint to validate the certificate manually! Certificate information: - Hostname: svn.aei.mpg.de - Valid: from Tue, 23 Feb 2010 16:02:12 GMT until Sun, 22 Feb 2015 16:02:12 GMT - Issuer: Max-Planck-Gesellschaft, DE - Fingerprint: 03:b4:e8:6e:d9:09:e9:93:72:e9:ff:fa:df:e4:2c:6d:1d:2a:e4:66 (R)eject, accept (t)emporarily or accept (p)ermanently? p After accepting the certificate and restarting the checkout proceeded without problems. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/68> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #181: AEILocalInterp should not off-centre the interpolation stencil by default

#181: AEILocalInterp should not off-centre the interpolation stencil by default ----------------------------+----------------------------------------------- Reporter: hinder | Owner: Type: defect | Status: new Priority: minor | Milestone: Component: Cactus | Version: Keywords: AEILocalInterp | ----------------------------+----------------------------------------------- AEILocalInterp by default will off-centre the interpolation stencil if there are insufficient points to perform the interpolation. In a parallel setting, this could happen due to there being insufficient ghost points for the interpolator chosen. The off-centering leads to an interpolation error which is of the correct order but larger than for a centered stencil. More importantly, it leads to different results on different numbers of processes. This violates a basic design principle of Cactus, and the expectation of users, that changing the number of processors should not change the results of a simulation. I propose that instead of silently off-centering the stencil, AEILocalInterp should abort with an error indicating that there are insufficient ghost-zones. The interpolator options corresponding to this are: boundary_off_centering_tolerance={0.0 0.0 0.0 0.0 0.0 0.0} boundary_extrapolation_tolerance={0.0 0.0 0.0 0.0 0.0 0.0} -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/181> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[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] #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
