Levels

• noop: disable optimizations
• advanced: all optimizations
• advanced-fsg: alternative optimization pipeline

Options (type, default)

• Parallelism:
  • openmp (boolean, False): enable/disable OpenMP parallelism
  • par-collapse-ncores (int, 4): control loop collapsing
  • par-collapse-work (int, 100): control loop collapsing
  • par-chunk-nonaffine (int, 3): control chunk size in nonaffine loops
  • par-dynamic-work (int, 10): switch between dynamic and static scheduling
  • par-nested (int, 2): control nested parallelism
• Blocking:
  • blockinner (boolean, False): enable/disable loop blocking along innermost loop
  • blocklevels (int, 1): 1 => classic loop blocking; 2 for two-level hierarchical blocking; etc.
• CIRE:
  • min-storage (boolean, False): smaller working set size, less loop fusion
  • cire-rotate (boolean, False): smaller working set size, fewer parallel dimensions
  • cire-maxpar (boolean, False): bigger working set size, more parallelism
  • cire-ftemps (boolean, False): give user control over the allocated temporaries
  • cire-mingain (int, 10): minimum gain to optimize away a redundant expression
  • cire-schedule ((str, int), 'automatic'): scheduling strategy for derivatives
• Device-specific:
  • gpu-fit (boolean, False): list of saved TimeFunctions that fit in the device memory
  • par-disabled (boolean, True): enable/disable parallelism on the host
• Misc:
  • linearize (boolean, False): linearize array accesses
