A Parallel Virtual Machine for Bulk Synchronous Parallel ML [PDF]

open access: yes, 2003
We have designed a functional data-parallel language called BSML for programming bulk-synchronous parallel (BSP) algorithms. The execution time can be estimated and dead-locks and indeterminism are avoided. The BSMLlib library has been implemented for the Objective Caml language.
