SPEC CFP95: 145.fpppp


  • From the Gaussian series of quantum chemistry benchmarks (two electron integral derivative).
  • The atoms in 145.fpppp are placed in a relatively compact region of space positioned in a graphite-like lattice. To accomplish this, code has been added that computes an atom's coordinates a a site on an orthorhombic lattice with a Gaussian deviation. The '92 version had a mistakenly linear arrangement of the atoms.
  • Cannot be parallelized (the behavior of each atom is affected be the behavior of each one of the other atoms).
  • Minimal cache footprint. Mostly a test of register allocation/performance.
  • Good exhibition of superscaler performance features.

Rough estimates of some of the basic hardware level activities: CPI, I- and D-cache activity, and TLB activity. This data is only useful for comparing the '95 benchmarks, not for comparing against any particular hardware.
