Benchmarks: SPIRAL Generated Programs

On this website we collect a few benchmarks including relevant papers. See also our collection of code and our online generator.

Note that in all benchmarks shown, Spiral code was generated ("push-button"), i.e., written by a computer. Learn about the current Spiral system.

On the left side we consider the discrete Fourier transform only but different parallel platform paradigms:

SMP (Multicore)/Vector code (code using SIMD short vector instructions and multiple threads for recent chip multiporcessors)
Code for GPUs (Graphical Processing Units)
Cell processor code
Distributed memory parallel code (code for clusters)
Verilog for FPGAs
FPGA accelerated software

On the right side we consider different numerical kernels

Walsh-Hadamard transform
FIR filters
Viterbi decoding
Other functionality

SMP (Multicore)/Vector Code

Our generated multi-threaded code uses a fast barrier.

4-way vectorized, up to 4 threads:
