[TOC]
The FFT Benchmarking Initiative (FBI) provides a framework for Fast Fourier Transform (FFT) benchmarks targeting exascale computing systems. It evaluates performance and scalability of distributed FFTs on different architectures. Furthermore, it analyzes the effect on applications that directly depend on FFTs. It can also stress and test the overall network of a supercomputer, give an indication on bisection bandwidth, noise, and other network and MPI collectives limitations that are of interest to many other ECP applications.
The current harness software allows to compute 3-D complex-to-complex and real-to-complex FFTs.
mkdir build; cd $_
build/
cmake ..
make -j
Integrated libraries: heFFTe, FFTMPI and AccFFT.
In progress: P3DFFT, FFTE, SWFFT, 2DECOMP&FFT, nb3dFFT, FFTW
Running examples:
mpirun -n 2 ./test3D_CPU_C2C
mpirun -n 2 ./test3D_CPU_R2C
- Installation and a Doxygen documentation will be available shortly.
For assistance with FBI, email aayala@icl.utk.edu or start a GitHub issue.
