------

|
To launch a set of experiments with t-mpi-distrib-exp:
|
|
|
|
0) Compile it:
|
|
|
|
mpic++ -o distrib-exp t-mpi-distrib-exp.cpp -I../../src/ -I../../src/mpi/ -DWITH_MPI -L ../../../build/eo/lib/ -leoutils -leo -leompi -leoserial
|
|
|
|
1) Generate the experiments, thanks to the script gen-xp.py
|
|
This script will guide you and ask you for all experiments. The prefix is used in the results filenames.
|
|
You may want to modify the name of the experiments file (default value: "experiments.json") or
|
|
the pattern of the results files. However, you have to ensure that the pattern is an one-to-one
|
|
function of the parameters, otherwise some results could be lost.
|
|
|
|
2) Launch the t-mpi-distrib-exp program with mpirun:
|
|
For 4 cores (= 1 master + 3 workers)
|
|
mpirun -np 4 ./t-mpi-distrib-exp --use-experiment-file=1 --experiment-file=/home/eodev/eo/test/mpi/experiments.json
|
|
|
|
For 16 cores (= 1 master + 15 workers)
|
|
mpirun -np 5 ./t-mpi-distrib-exp --use-experiment-file=1 --experiment-file=/home/eodev/eo/test/mpi/experiments.json
|
|
|
|
3) The program will generate the results of the experiments, as txt files. There is one result file for each run of each
|
|
experiment.
