Present: Erik, Peter, Ian, Yosef, Matt, Roland automated tests:
* want to run tests periodically on production machines rather than just in Ubuntu VM to test other compilers/MPI implementation than gcc/OpenMPI * Ian has setup for Datura under development, add other machines once system is stable. This method runs Jenkins on the head node. * add short (20min or so) simulation to tests to check more complex setups ET workshop: * David Rideout offered to give a presentation (private email to Erik, hope I did not get this wrong) * goals: ** ES wants to improve Carpet scalability to >10^4-10^5 processors ** (known) bottlenecks are: bboxset class, any lower-d IO which serializes it seems * PLEASE think of topics for the workshop and post them to the mailing list occasional hangs in MPI reported by Yosef: * hangs occur with or without the parity thorn * hangs occur on RIT cluster (with parity thorn, mvapich) * hangs occur on Stampede (no parity thorn, IMPI) * Ian saw codes hang in ibrun when MPI versions did not match, this seems to not be the case here Yours, Roland
