HPX based FFT with FFTW3 as 1D backend and FFTW3 with HPX backend

This repo is currently under active developement.

Structure

• /src contains different shared-memory and distributed implementations of the same 2D FFT example

• /benchmark contains sbatch scripts to launch strong scaling tests

Run

Shared

All:

• ./shared_benchmark.sh estimate/measure partition_name

Executables only:

• fft_hpx_loop_shared/fft_hpx_task_sync_shared/fft_hpx_task_shared/fft_hpx_task_naive_shared /fft_hpx_task_agas_shared/fft_hpx_loop/fft_hpx_task_agas: sbatch -p $PARTITION -N 1 -n 1 -c $THREADS run_hpx_shared.sh executable_name estimate/measure $THREAD_POW

• fftw_hpx/fftw_mpi_threads/fftw_mpi_omp: sbatch -p $PARTITION -N 1 -n 1 -c $THREADS run_fftw_shared.sh executable_name estimate/measure $THREAD_POW
