  • Group Comms weren't working for Comms of powers of 2. Nathan found massive memory issue.
  • openib - sounds like we have a localized fix in the works. Nathan.
    • Nathan's been delayed until later this week. Could get done by middle of next week.
    • openib btl specific could be made to only progress if there is a send/recv message posted.
      • _______ progress also progresses connections.
      • ugeniee progress - could only check for data grams every (only 200ns hit).
    • Prefer to stick with nathan's original decay function without modifying openib.
