#1617: Calls to Accelerator_NotifyDataModified should be paired with calls to Accelerator_RequireInvalidData -----------------------------------+---------------------------------------- Reporter: sbrandt | Owner: Type: defect | Status: new Priority: minor | Milestone: Cactus_4.3.0 Component: EinsteinToolkit thorn | Version: development version Keywords: | -----------------------------------+---------------------------------------- Calls to Accelerator_NotifyDataModified should be paired with calls to Accelerator_RequireInvalidData, otherwise there's a risk of seg fault in Accelerator_NotifyDataModified due to a missing accelerator data structure. MoL fails to do this in Operators.c. Patch attached. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1617> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

#1612: reace condition when building Cactus utilities --------------------+------------------------------------------------------- Reporter: rhaas | Owner: Type: defect | Status: new Priority: minor | Milestone: Component: Cactus | Version: development version Keywords: | --------------------+------------------------------------------------------- I just compiled on bluewaters and received output {{{ Done creating cactus_simO3. All done ! Building utilities for simO3 Building utilities for simO3 ... Creating hdf5_recombiner in /mnt/a/u/sciteam/rhaas/ET_trunk/exe/simO3 from /mnt/a/u/sciteam/rhaas/ET_trunk/configs/simO3/build/CarpetIOHDF5/hdf5_recombiner.o mkdir: cannot create directory `/tmp/1399318629': File exists mkdir: cannot create directory `/tmp/1399318629': File exists }}} with the full (last part of) the log in the attached file. So it seems as if we have a race condition in the make system that causes it to try and build the utilities twice (in parallel). On bluewaters simfactory (which I used) builds Cactus using 16 processes. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1612> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #1361: disable hyperthreading in loopcontrol by default

#1361: disable hyperthreading in loopcontrol by default -----------------------------------+---------------------------------------- Reporter: rhaas | Owner: Type: defect | Status: new Priority: major | Milestone: Component: EinsteinToolkit thorn | Version: Keywords: LoopControl | -----------------------------------+---------------------------------------- when running with both openmp and sufficiently many threads that hyperthreading threads are used, many tests using LoopControl (Cartoon, RotatingSymmety180, RotatingSymmetry90) fail. This can be tracked down to disabling hyperthreading support in LoopControl (ie. turning of hyperthreading makes things work). In particular on bethe with smt and 8 physical cores: The Cartoon/test_cartoon_2.par test shows differences from the recorded results when run with 16 threads (but not with 8 threads). If I then go ahead and disable OMP in all ML source files but ML_BSSN_enforce *and* comment out the #include "loopcontrol.h", then the difference goes away. Adding back #include "loopcontrol.h" brings back the error. Some further experimenting with LoopControl's options shows that indeed the use_smt_threads option is what causes problems. If I turn it off things work fine even with a vanilla source tree. Otherwise relative differences are on the order 1e-7 and absolute 1e-11 (in momx_z_[2][2].xg). Without smt the results are identical to the stored values. The issue only occurs in combination of OpenMP, vectorization and hyperthreading. The issue is independent of the compiler (both intel 13 and gcc 4.4 show the same behaviour), and vectorization (sse2) and many threads (up to 4 times the number of physical cores) works fine on non-smt machines. I propose to disable LoopControl::use_smt_threads by default. Note that we cannot completely remove it since apparently for Vesta (a Blue Gene/Q) smt is required to get and multi-threading at all. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1361> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

#997: problem in appending output after recovery ----------------------------------------+----------------------------------- Reporter: corvino.giovanni@… | Owner: eschnett Type: defect | Status: new Priority: major | Milestone: Component: Carpet | Version: Keywords: | ----------------------------------------+----------------------------------- I have a problem in appending output files from Carpet. I used to produce 3d HDF5 output of grid variables and write the output in the same directory also after recovery from checkpoint. The new output was automatically appended to the existing one. Now I am producing h5 output also on 2D slices but in this case the output is overwritten so I lost the data for all but the last recovery. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/997> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

The maximum absolute difference is about 1e-10, the maximum relative difference about 1e-11. This seems like a problem with tolerances. Can someone with GRHydro experience check? -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1730> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit
