Fit to programme
This was a proposed solution answering Task 003: Code Performance Assessment, behind WP 1.1.
Description
A GPU implantation of interactions is being developed by the Celeritas team, based at the Oak Ridge laboratory in the US in collaboration with colleagues at Warwick Universities. A recent review conducted at CERN demonstrated a good physics performance of this implementation and an initial integration with the ATLAS experiment software. The goal of this mini-project is to use the existing Celeritas code implementation to
- assess the performance of the code, via the use of profilers to identify potential bottleneck,
- assess the impact of the use of single vs double precision floating points,
- assess the ability to run code on AMD GPUs compared to the original CUDA implementation.
