This directory contains source for busy-wait barrier synchronization
algorithms, as described in "Fast, Contention-Free Combining Tree
Barriers," by Michael L. Scott and John M. Mellor-Crummey (to appear,
International Journal of Parallel Programming, 1994).  There are
three files, one each for the BBN Butterfly 1, the BBN TC2000,
and the Kendall Square KSR-1.  All three files are in compressed tar
format.
