Abstrao, a SME located in Toulouse, is specialized in integrating numerical modelling into the analysis and optimization of systems subjected to extreme loading. The company develops an explicit non-linear reference software dedicated to space applications, they needed a first evaluation of the scalability of a multi-GPU HPC version of the code.
At the end of 2023, the company consulted its Regional Computing Center, CALMIP, which is one of the 21 Mesocenters involved in CC-FR. This partnership has enabled the company to take advantage of the Mesocenter's infrastructure and technical expertise.
A study of strong and weak scalability has been carried out on MESONET ARM supercomputer “Turpan” which is hosted at CALMIP. The calculations also made it possible to demonstrate the applicability of the software to simulate hypervelocity impacts of space debris on satellite protective structures.
Business impact:
The collaboration between CALMIP (one of the 21 Mesocenters involved in CC-FR) and ABSTRAO has been decisive in the first evaluation of the ABSTRAO HPC Solver performances. This partnership has enabled a comprehensive and rigorous assessment of the solver's multi-GPU HPC capabilities.
Benefits:
- Very good weak and strong scalability (90%) on 30xA100 on Turpan - MESONET ARM supercomputer
- Significant progress in code maturity
