Added

  • Adding GPU support (see example 3_molecular_dynamic_gpu)

Added

  • Dynamic Load balancing
  • Added SPH Dam break with Dynamic load balancing (7_sph_dlb)(7_sph_dlb_opt)
  • Added automatic procedure for update ./install --update and --upgrade (From 0.8.0 version will have a long term support for bug fixing. End-of-life of 0.8.0 is not decided yet, it should be still supported for bug fixing after release 0.9.0)
  • Added video lessons for Dynamic load balancing (openfpm.mpi-cbg.de) (website officially open)
  • Added for debugging the options PRINT_STACKTRACE, CHECKFOR_POSNAN, CHECKFOR_POSINF, CHECKFOR_PROPINF, CHECKFOR_PROPNAN, SE_CLASS3.

Added

  • Symmetric cell-list/verlet list Crossing scheme
  • VCluster examples
  • Cell-list crossing scheme

Fixed

  • CRITICAL BUG: OpenFPM has a bug handling decomposition when a processor has a disconnected domains (By experience this case has been seen on big number of processors).
  • Found and fixed a memory leak when using complex properties

Changed

  • The file VCluster has been mooved #include "VCluster.hpp" must be changed to #include "VCluster/VCluster.hpp" BECAUSE OF THIS, PLEASE CLEAN THE OPENFPM FOLDER OTHERWISE YOU WILL END TO HAVE 2 VCLUSTER.HPP
