	abstract = {Until now, most results reported for parallelism in production systems (rule-based systems) have been simulationresults  --  very  few  real  parallel  implementations  exist.    In  this  paper,  we  present  results  from  our  parallelimplementation of OPS5 on the Encore multiprocessor.  The implementation exploits very fine-grained parallelismto  achieve  significant  speed-ups.    For  one  of  the  applications,  we  achieve  12.4  fold  speed-up  using  13  processes.Our  implementation  is  also  distinct  from  other  parallel  implementations  in  that  we  parallelize  a  highly  optimizedC-based  implementation  of  OPS5.    Running  on  a  uniprocessor,  our  C-based  implementation  is  10-20  times  fasterthan  the  standard  lisp  implementation  distributed  by  Carnegie  Mellon  University.   In  addition  to  presenting  theperformance  numbers,  the  paper  discusses  the  amount  of  contention  observed  for  shared  data  structures,  and  thetechniques used to reduce such contention.},
