Welcome to the DGSWEM wiki!

Our current goal is to troubleshoot performance problems with the dgswem-hpx branch of the code.

Max and Zach have demonstrated that, when using Intel compilers, the Fortran sections of both codes perform the the same.

Zach is currently:

  • Attempting to get dgswem-hpx running on Rostam (Ste||ar group's research cluster) with VTune support enabled.
  • Determining the distribution of submeshes on localities by LibGeoDecomp's PTScotch partitioner
  • Refactoring his c++ based hpx dataflow code (runs only on single locality, does not use LGD)
  • Making sure there isn't anything special about the artificial square meshes that could cause performance problems
