New features:

  • Added tree-based termination detection for improved scalability over circle-based token passing. Enable with new CIRCLE_TERM_TREE flag during CIRCLE_init or CIRCLE_set_options.
  • Changed CIRCLE_abort() to use a tree-based broadcast from a direct send to all ranks.
  • Added CIRCLE_set_reduce_period(seconds) to customize period between consecutive reductions.
  • Added CIRCLE_set_tree_width(width) to customize width of internal communication tree.
  • Reduction callbacks invoked when work loop completes, in addition to periodically during the work loop

Bug fixes:

  • Compare to MPI_REQUEST_NULL instead of MPI_PROC_NULL to complete send request during token exchange.
  • configure script updated to detect MPICH
