TCM-July-2008

Date/Time/Location

15 July 2008, 6:30 pm, during RTA at Hagenberg

Agenda

• current status of the competition test run
  • the "Torpa problem" (what can programs expect on $PATH, $PWD)
  • the "Jambox problem" (programs that write long proofs)
  • Q: test run for certified termination?

• next steps
  • submission of new prover versions
  • submission of new problem (sets)
  • test runs (by submitters)
  • complete runs (by administrators)
  • evaluation (by committee) (how and when)

• new category suggestions
  • complexity analysis (Georg Moser, Johannes Waldmann)
  • SN infinity (Hans Zantema, Jörg Endrullis)
  • we have more categories than people?

• To discuss and clarify
  • RAM usage (unlimited I guess)
  • CPU usage (defined by wall time, so one may use 16 cores? CPU time, so 60 seconds singlethreaded translates to about 4 seconds with 16 threads?)
  • For CPU time limit the competition can run faster (if the tools run multithreaded), but there is no incentive to do so.
  • My opinion: Because the machines have 16 CPU cores each, multithreading should be encouraged (read: wall time!)

• details for Termination Workshop 2009 Leipzig
  • date? (needs to be decided soon, to book the venue)
  • length/schedule? suggestion:
    • (day 1) sub-workshop on certified termination
    • (day 2, 3) termination workshop (if there are more submission, then already start on afternoon of day 1)
    • (day 4) would be possible to hold the IFIP WG 1.6 meeting
  • program committee? suggestion: informal workshop, no refereeing, small committee, include people from communities of termination of logic programming, imperative programming
