CHANGELOG.md

Change Log

All notable changes to this project will be documented in this file.

[0.9.0]

Added

• Introduced getDomainIterator for Cell-list

Fixed

• Installation of PETSC in case with MUMPS try without MUMPS
• In case of miss compilation ignore system wide installation

[0.8.0] 28 February 2016

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 the possibility to write binary VTK files using VTK_WRITER and FORMAT_BINARY see 0_simple_vector for an example

Fixed

• Installation of PETSC with MUMPS

Changed

• BOOST updated to 1.63
• Eigen updated to 3.3.7

[0.7.1] 28 January 2016

Fixed

• Multiphase verlet single to all case generate overflow

[0.7.0] 15 December 2016

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

[0.6.0] - 5 November 2016

Added

• Symmetric cell-list/verlet list
• Multi-phase cell-list and Multi-phase cell-list
• Added ghost_get that keep properties
• Examples: 1_ghost_get_put it show how to use ghost_get and put with the new options 4_multiphase_celllist_verlet completely rewritten for new Cell-list and multiphase verlet 5_molecular_dynamic use case of symmetric cell-list and verlet list with ghost put 6_complex_usage It show how the flexibility of openfpm can be used to debug your program
• Plotting system can export graph in svg (to be included in the paper)

Fixed

• Option NO_POSITION was untested
• Regression: Examples code compilation was broken on OSX (Affect only 0.5.1) (Internal: Added OSX examples compilarion/running test in the release pipeline)
• gray_scott example code (variable not initialized)

Changes

[0.5.1] - 27 September 2016

Added

• ghost_put support for particles
• Full-Support for complex property on vector_dist (Serialization)
• Added examples for serialization of complex properties 4_Vector
• improved speed of the iterators

Fixed

• Installation PETSC installation fail in case of preinstalled MPI
• Miss-compilation of SUITESPARSE on gcc-6.2
• vector_dist with negative domain (Now supported)
• Grid 1D has been fixed
• One constructor of Box had arguments inverted. PLEASE CAREFULL ON THIS BUG float xmin[] = {0.0,0.0}; float xmax[] = {1.0,1.0}; // Box<2,float> box(xmax,xmin) BUG IT WAS xmax,xmin Box<2,float> box(xmin,xmax) <--- NOW IT IS xmin,xmax Box<2,float> box({0.0,0.0},{1.0,1.0}) <---- This constructor is not affected by the BUG

Changed

• On gcc the -fext-numeric-literals compilation flag is now mandatory

[0.5.0] - 15 August 2016

Added

• map communicate particles across processors mooving the information of all the particle map_list give the possibility to give a list of property to move from one to another processor
• Numeric: Finite Differences discretization with matrix contruction and parallel solvers (See example ... )
• vector_dist now support complex object like Point VectorS Box ... , with no limitation and more generic object like std::vector ... (WARNING TEMPORARY LIMITATION: Communication is not supported property must be excluded from communication using map_list and ghost_get)
• vector_dist support expressions (See example ...)
• No limit to ghost extension (they can be arbitrary extended)
• Multi-phase CellList
• Hilber curve data and computation reordering for cache firndliness

Fixed

• Removed small crash for small grid and big number of processors

Changed

[0.4.0] - 26-05-2016

Added

• Grid with periodic boundary conditions
• VTK Writer for distributed vector, now is the default writer
• Installation of linear algebra packages
