Inputs and trace's reports

We collect 3 trace of VLC's allocation when doing:
  1. Start program => report input 1
  2. Play an MP3 (5.4mb - 4:10) => report input 2
  3. Play 5 minutes of an AVI video (697.7mb - 53:02) => report input 3
You can find all MallocLab's traces for VLC here.

Allocator's configurations

  1. BSA => Original BSA with page allocation and alternate split side (AS)
  2. TLSF => Two Level Segregate allocator
  3. BSA-- => BSA with no split or coalesce and no AS
  4. BSA++ 10 => BSA++ with no AS, popularity index threshold 10
  5. BSA++ (npa) 10 => BSA++ with no AS, no page allocatione (npa), popularity index threshold 10
  6. BSA++ AS 10 => BSA++ with AS, popularity index threshold 10
  7. BSA++ AVG 10 => BSA++ with no AS, average popularity threshold 10
  8. BSA++ AVG (npa) 10 => BSA++ with no AS, npa, average popularity threshold 10
  9. BSA++ AS AVG 10 => BSA++ with AS, npa, average popularity threshold 10
  10. BSA++ VAR 345 => BSA++ with no AS, popularity index threshold >= 15, variance popularity threshold 345
  11. BSA++ VAR (npa) 345 => BSA++ with no AS, npa, popularity index threshold >= 15, variance popularity threshold 345
  12. BSA++ VAR AS 345 => BSA++ with AS, popularity index threshold >= 15, variance popularity threshold 345
Some of these allocators have been tested with different threshold: In this page we show only the winner for each type of allocator's configuration. Read BSA or BSA++ description in order to understand all features listed above.
