Last change on this file since 13c5e19 was 13c5e19, checked in by Thierry Delisle <tdelisle@…>, 6 years ago
  • Moved snzi and subqueues outside of ready_queue.cfa.
  • Added random.hfa with multiple prng.
  • Minor optimizations to ready-queue
  • Stats now track number of local pops( bias pops )
  • Fixed stats for io
  • Fixed calculaton of nprocessors
  • Fixed IO to work with new ready-queue
  • Property mode set to 100644
