Presentation

Smilei is a Particle-In-Cell code for plasma simulation. Open-source, collaborative, user-friendly and designed for high performances on super-computers, it is applied to a wide range of physics studies: from relativistic laser-plasma interaction to astrophysics.

Compilation and simulation

Download

Sources are available at: https://github.com/SmileiPIC/Smilei

For the test, we will use a specific release. To download this release, run:

./download.sh

Compile

Information (if needed) about how to compile the application.

For instance:

Compile the code using:

source machines/occigen-bdw/env
./compile.sh

machines/occigen-bdw/env contains the information for compilation (module load gcc openmpi lapack hdf5 ...)

Run and validate the simulation

For each test case, given in a separate folder (e.g. testcase_small), you can find three scripts:

• prepare.sh: prepare the simulation (move data to the right location, recompile some minor changes, ...)
• run.sh : run the application and print out the evaluated metric
• validate.sh: validation of the simulation on a scientific point of view

For running and validating the simulation, one should be able to do:

cd testcase_XXX
./prepare.sh
./run.sh
./validate.sh

And getting no error code returned. Those steps can also be used in a batch file for running the simulation using a job scheduler.
