[Einstein Toolkit] #304: SimFactory should not clean-up so aggressively

#304: SimFactory should not clean-up so aggressively ------------------------+--------------------------------------------------- Reporter: hinder | Owner: mthomas Type: defect | Status: new Priority: major | Milestone: Component: SimFactory | Version: Keywords: | ------------------------+--------------------------------------------------- As far as I can tell, SimFactory 2 currently cleans up all simulations every time it is run. This is not scalable - if you are running with a slow production filesystem, just statting all the simulations could take a very long time. Similarly, if you do a sim sync, it currently cleans up all the simulations on your local machine, as well as the remote machine. Running sim --help even cleans up all your simulations! This behaviour is very counter-intuitive (certainly not what a user would expect) and not suitable for production systems. I propose that simfactory should only clean up the simulation which is being referred to in the current command. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/304> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #328: TRAC frequently logs users out

#328: TRAC frequently logs users out ----------------------------------+----------------------------------------- Reporter: hinder | Owner: Type: defect | Status: new Priority: minor | Milestone: Component: EinsteinToolkit trac | Version: Keywords: | ----------------------------------+----------------------------------------- There seems to be some mechanism which is automatically logging users out of TRAC. This means that they end up posting as "anonymous" because they don't realise they are logged out. Probably there is a session cookie which expires or something. To avoid this, we could either try to change the logout (I would be happy if the automatic logout was just disabled completely), or make it much more obvious when you are not logged in. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/328> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

#375: RotatingSymmetry*: Improve performance -------------------------+-------------------------------------------------- Reporter: eschnett | Owner: Type: enhancement | Status: new Priority: major | Milestone: Component: Cactus | Version: Keywords: | -------------------------+-------------------------------------------------- The attached patches depend on the new Slab API provided by ticket #374: Use the new Slab API to set up the communication schedule only once (per regridding), which saves some communication time when applying symmetries. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/375> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

#374: CactusNumeric/Slab: Improve performance -------------------------+-------------------------------------------------- Reporter: eschnett | Owner: Type: enhancement | Status: new Priority: major | Milestone: Component: Cactus | Version: Keywords: | -------------------------+-------------------------------------------------- The attached patch does the following, prompted by performance problems reported by Christian Ott: Reorganise some of the internals of thorn Slab: Use LoopControl to parallelise loops via OpenMP. Refactor the "work horse" routines that perform the actual copy routines. These routines are specialised for common cases that need to execute efficiently, in particular for the cases encountered in RotatingSymmetry90 and RotatingSymmetry180 when handling CCTK_REAL variables. Offer an additional API (Slab_MultiTransfer_Init, Slab_MultiTransfer_Apply, Slab_MultiTransfer_Finalize) that calculates the communication schedule only once, and then re-uses it in further calls. This avoids some communication overhead. Remove old CVS header comments. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/374> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

#383: SimFactory 1 does not create source directory on login ------------------------+--------------------------------------------------- Reporter: hinder | Owner: mthomas Type: defect | Status: new Priority: major | Milestone: ET_2011_05 Component: SimFactory | Version: Keywords: | ------------------------+--------------------------------------------------- If I run "sim login <machine>" to a machine where the remote source directory does not exist, the login fails with bash: line 0: cd: /nics/d/home/hinder/Cactus/etrelease: No such file or directory Connection to kraken-gsi2.nics.teragrid.org closed. If I run a "sim sync" first, then a subsequent sim login works correctly.

[Einstein Toolkit] #363: Make TimerReport output average/min/max timings to stdout, instead of timings from the root process

#363: Make TimerReport output average/min/max timings to stdout, instead of timings from the root process ----------------------+----------------------------------------------------- Reporter: eschnett | Owner: Type: defect | Status: new Priority: major | Milestone: Component: Cactus | Version: Keywords: | ----------------------+----------------------------------------------------- The n_top_timers feature of TimerReport outputs timings from the root process only to stdout, greatly confusing people. It should instead output average (or min/max) timings over all processes. One common problem is a routine that contains communication, and which thus has to wait until all processes arrive there. If previous routines show a load imbalance, then outputting timings only from the root process make this routine look very slow, although this routine really only has to wait for other processes finish their previous calculations. Since this is a common case, it makes the current timing output useless for all routines involving communication. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/363> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit
