In this repository you can find some of the code used to carry out the parallel computing project.
2d_fft_seq_v2.0.cpp and 2d_fft_par_v2.1.cpp contain the source code of the sequential and parallel implementation respectively.
compile_seq.txt and compile_par.txt contain the commands used to compile the sequential and parallel implementation respectively. CAPRI did not allow me to compile with spack load [email protected] but, after consulting some online documentation, I was able to compile with module load intel-parallel-studio-professional.2019.4-gcc-8.2.1-fnvratt instead. CAPRI would also not compile with mpicc or mpicxx thus to compile I used the Intel compiler (mpiicc). To be more fair in the comparison I also compiled the sequential code with the Intel compiler (icc).
The programs are executed with: ./2d_fft_{par|seq} "<filename>" <vertical_resolution> <horizontal_resolution>
e.g.: ./2d_fft_seq "input_file.txt" 1080 1920
The files .slurm contain examples of tasks scheduled on CAPRI.
The files 2d_fft_par_8_out_160865.txt and 2d_fft_seq_out_160926.txt contain example outputs of the program, for the parallel and sequential case respectively.
Details about the project can be found in the .pdf report (not in the repository).
