MPISound

This project is an audio profiler of Message Passing Interface. For MPI operation representation MPISound use stereo system (left headphone is master rank and right headphone is second process). Therefore only two processes are supported for this time.

Usage

You can specify library when your project compiled or you can use LD_PRELOAD instead (also you need to specify path to MPI library in mpi_sound.cpp)

mpic++ -shared -fPIC ../sources/mpi_sound.cpp -o sound.so
LD_PRELOAD='./sound.so' mpirun -np 2 ./send_recv

Then some log files will be created (rank_0_output.t). If you run

./MPISound

it will use the files to create WAV sound file.
