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.

BSPlib standard and implementation

Standard: BSPlib: the BSP Programming Library, by Jonathan Hill, Bill McColl, Dan Stefanescu, Mark Goudreau, Kevin Lang, Satish Rao, Torsten Suel, Thanasis Tsantilas, and Rob Bisseling, version with C examples or with Fortran 77 examples. Published in Parallel Computing 24 (1998) pp. 1947-1980.


  • Oxford BSP toolset.
  • Alternative implementation (with extensions) Paderborn PUB library.
  • Recent patches by Peter Krusche (University of Warwick) to make the Oxford BSP toolset and PUB running on an SGI Altix machine. Released October 2005.
  • BSPonMPI by Wijnand J. Suijlen (Utrecht University). Open-source project at SourceForge. Provides BSPlib version on top of MPI. Makes BSPlib portable to almost every parallel computer. Version 0.2 released July 2006. Version 0.3 fixes a bug on certain architectures and will offically be released February/March 2010. It is already available here: BSPonMPI version 0.3
  • MulticoreBSP for C released August 29, 2012. A BSPlib version in C aimed at multicore architectures, developed by Albert-Jan Yzelman at the KU Leuven and the Intel ExaScience Lab.
