BSP Worldwide

BSP Worldwide is an association of people interested in the development of the Bulk Synchronous Parallel (BSP) computing model for parallel programming. It exists to provide a convenient means for the exchange of ideas and experiences about BSP and to stimulate the use of the BSP model. Areas of interest of BSP Worldwide include:

  • Research into properties of the model
  • Application of the model to programming tasks of all kinds including the scheduling of parallel execution
  • Performance benchmarking and comparison with other approaches
  • Cost modelling and performance prediction
  • Definition of standard functions for programming in the BSP style
  • Implementation of programming tools to support the use of the model

The organisation does not have a formal structure. Its activities depend on contributions by volunteers, BSP users, and developers. Its main means of communication is a mailing list, bspall, and this website.
