- 03/28/12: Public release of PolyBench/Fortran 1.0 Download. PolyBench/Fortran is a port of PolyBench/C 3.2 in Fortran, written by Mohanish Narayan.
Description
PolyBench is a collection of benchmarks containing static control parts. The purpose is to uniformize the execution and monitoring of kernels, typically used in past and current publications. 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 !$pragma scop and !$pragma endscop delimiters.

Sample compilation commands
To compile a benchmark without any monitoring
# Build utilities first $> gcc -c utilities/fpolybench.c -o utilities/fpolybench.o # Build the benchmark $> gfortran -ffree-line-length-none linear-algebra/kernels/atax/atax.F90 -Iutilities utilities/fpolybench.o -o atax_base
To compile a benchmark with execution time reporting
# Build utilities first $> gcc -c -DPOLYBENCH_TIME utilities/fpolybench.c -o utilities/fpolybench.o # Build the benchmark $> gfortran -ffree-line-length-none -DPOLYBENCH_TIME linear-algebra/kernels/atax/atax.F90 -Iutilities utilities/fpolybench.o -o atax_time
To generate the reference output of a benchmark
# Build utilities first $> gcc -c utilities/fpolybench.c -o utilities/fpolybench.o # Build the benchmark $> gfortran -ffree-line-length-none -O0 -DPOLYBENCH_DUMP_ARRAYS linear-algebra/kernels/atax/atax.F90 -Iutilities utilities/fpolybench.o -o atax_ref $> ./atax_ref 2>atax_ref.out
Some available options
They are all passed as macro definitions during compilation time (e.g, -Dname_of_the_option).
