• CRM: Column Radiation Model extracted from the CCM

  • 6% of floating point operations are sqrt, 3% are fdiv
  • exp, log, and pow are among top six most frequently called functions

• Fixed vertical dimension (18 levels) and total number of columns (512)

• Varying number of columns per chunk

• Complicating factors

  • Compiler optimizations
