[Einstein Toolkit] #1547: issues with stampede

#1547: issues with stampede ----------------------------+----------------------------------------------- Reporter: jchsma@… | Owner: Type: defect | Status: new Priority: major | Milestone: Component: Other | Version: ET_2013_11 Keywords: | ----------------------------+----------------------------------------------- Over the past few months, I have been using RIT's LazEv code with only minor hiccups on stampede (particularly, the unreproducible 'dapl_conn_rc' crashes that I'm sure other stampede users are familiar with). This checkout was of the previous release, ET_2013_05, and compiled with Intel MPI. Most of the jobs I ran took advantage of some symmetry, and I was able to run on 12-16 nodes at about 50-60% memory usage. After the sync issue was backported, I checked out the new release, ET_2013_11 and immediately ran into problems. The first issue was with the run performance and LoopControl, which, with the mailing lists help, we sorted out. The second was with crashes and checkpointing. With both Intel MPI and MVAPICH2 configurations, the code would hang (~50% of the time) when dumping checkpoints, and 100% when dumping a termination checkpoint. Further, the crashes seem more frequent, and I couldn't get a simulation to run for a full 24 hours without crashing (either by stalling on checkpointing or otherwise). So, I checked out a clean version of the toolkit, with only toolkit thorns, and removed any thorns specific to RIT. I compiled with both the Intel MPI and MVAPICH2 configurations in simfactory. In both cases, I can run the 'qc0-mclachlan.par' file to completion with no issues. So I edited the qc0 parfile to update the grid, remove the symmetries, and update the initial data to match my test parameter file. I ran the job on 20 nodes, and with either configuration, I was not successful in running the job to completion on any of my numerous attempts. Intel MPI runs die with the standard unhelpful "dapl_conn_rc" error at random times in the evolution, and the MVAPICH2 dies with: [c431-903.stampede.tacc.utexas.edu:mpispawn_7][readline] Unexpected End- Of-File on file descriptor 6. MPI process died? [c431-903.stampede.tacc.utexas.edu:mpispawn_7][mtpmi_processops] Error while reading PMI socket. MPI process died? [c431-903.stampede.tacc.utexas.edu:mpispawn_7][child_handler] MPI process (rank: 15, pid: 106620) terminated with signal 9 -> abort job [c429-501.stampede.tacc.utexas.edu:mpirun_rsh][process_mpispawn_connection] mpispawn_7 from node c431-903 aborted: Error while reading a PMI socket (4) The IMPI jobs died with the same dapl_conn_rc error at run times of 2 hours, 8 hours, and 21 hours. I also had one job that hung and did not exit until it was killed by the queue manager. The MVAPICH2 jobs died at around 3 hours and 8 hours with the error above. We've been in contact with TACC and they said it was a Cactus issue, so I am sending this report. Attached is the parameter file I used for the tests. They should work with a stock ET_2013_11 checkout. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1547> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #980: Remove support for the flesh-based MPI mechanism

#980: Remove support for the flesh-based MPI mechanism -------------------------+-------------------------------------------------- Reporter: hinder | Owner: Type: enhancement | Status: new Priority: major | Milestone: Component: Cactus | Version: Keywords: | -------------------------+-------------------------------------------------- The flesh-based MPI mechanism has just been deprecated in favour of ExternalLibraries/MPI. Even though the latter is new, it is probably a good idea to completely disable the old mechanism since having any mixture of thorns/optionlists using the old and new mechanisms is completely untested and will likely lead to problems and confusion. It's better to give a useful fatal error message if someone still specifies "MPI = " in their optionlist than to have things break in other weird and wonderful ways. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/980> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

The new 14.04 stable release is now available, and we should test on that instead. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1638> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #1390: parameter file parser aborts when findeing first error

#1390: parameter file parser aborts when findeing first error --------------------+------------------------------------------------------- Reporter: rhaas | Owner: Type: defect | Status: new Priority: major | Milestone: Component: Cactus | Version: development version Keywords: | --------------------+------------------------------------------------------- The attached parfile contains multiple errors (one per line). However the parameter file parser only reports the first one, then stops. This makes verifying parfiles for correctness hard. It might be good to defer aborting until the end of the file or until a larger number of parsing errors were encountered. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1390> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #1276: Intel 2013.1.117 mis-compiles NewRad

#1276: Intel 2013.1.117 mis-compiles NewRad -----------------------------------+---------------------------------------- Reporter: rhaas | Owner: Type: defect | Status: new Priority: minor | Milestone: Component: EinsteinToolkit thorn | Version: Keywords: NewRad | -----------------------------------+---------------------------------------- Intels compiler fails (with -O2) to push values for bmin onto the stack in lines 316 of newrad.cc and line 126 of extrap.cc. Adding printf's for bmin perturbs the bug out of existence, but adding a printf of the address of bmax and reveals that at the time extrap_kernel is call the integer just before this address is still the initialization value of bmin[2] and not the correct value. The attached patch disables optimization for the two driver functions affected (but not the actual kernel). The patch is specific (via an #if) for this particular compiler and version. What is the best way of handling this? Target any intel version starting from the known failing one until we know of known good one? Or starting from an older known good one (that would be intel 11 in my case). Hopefully no similar bug is triggered by Carpet's use of the same idiom. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1276> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit
