The PICSAR project (now released open-source!)
The Particle-In-Cell Scalable Application Resource (PICSAR) is a high performance repository intended to help scientists porting their Particle-In-Cell (PIC) codes to the next generation of exascale computers.
PICSAR exploits the three levels of parallelism that will be required to achieve good performances on future architectures: distributed memory parallelization (internode), shared memory parallelization (intranode) and vectorization.
- A high performance library of optimized versions of the key functionalities of the PIC loop.
- A compact “mini-app” standalone code, which serves as a self-contained proxy that adequately portrays the computational loads and dataflow of more complex PIC codes.
- A Python wrapper for using PICSAR optimized routines with Python-driven codes.
