Description

PolyBench is a benchmark suite of 30 numerical computations with
static control flow, extracted from operations in various application
domains (linear algebra computations, image processing, physics
simulation, dynamic programming, statistics, etc.). PolyBench features
include:

  • A single file, tunable at compile-time, used for the kernel
    instrumentation. It performs extra operations such as cache flushing
    before the kernel execution, and can set real-time scheduling to
    prevent OS interference.
  • Non-null data initialization, and live-out data dump.
  • Syntactic constructs to prevent any dead code elimination on the kernel.
  • Parametric loop bounds in the kernels, for general-purpose implementation.
  • Clear kernel marking, using pragma-based delimiters.

PolyBench is currently available in C and in Fortran:

  • See PolyBench/C 4.0 for the C version
  • See PolyBench/Fortran 1.0 for the Fortran version (based on PolyBench/C 3.2)
