About this role
❓ About SiPearl… SiPearl is the European fabless designer of sovereign secure high-performance energy-efficient CPUs for HPC, AI and data centres. These CPUs will help address strategic challenges in the fields of security, defence, medical research, energy, climate and engineering with a reduced environmental footprint. In June 25, SiPearl completed the design of the most complex CPU ever designed in Europe, Rhea1. Featuring 80 Arm Neoverse V1 cores, with 61 billion transistors, it is currently in production at TSMC. Sipearl CPUs will equip the two first European exascale supercomputers belonging to EuroHPC JU: Rhea1 will be integrated into the JUPITER machine based in Germany and Rhea2 will be part of Alice Recoque in France. Incubated within the European Processor Initiative (EPI) consortium and seed-funded by the European Union, SiPearl employs almost 200 people in : • France (Maisons-Laffitte, Grenoble, Massy, Sophia Antipolis), • Spain (Barcelona) • and Italy (Bologna) 🎯Your missions during this internship In this context you will be involved in the optimization and the strengthening of the ecosystem (compilers, libraries, and tools) by exploiting both SVE vectorization and heterogeneous memories. You will therefore be responsible for carrying out the following tasks: • Ensuring the libraries compatibility with the Rhea1 architecture. • Ensure full support for the features of open-source and internal libraries. • Propose and implement optimizations. • Track issues, features and bugfixes in these libraries and provide patch(s). • Evaluate and validate work through testsuites, benchmarks and HPC codes (in collaboration with the Benchmarks teams). Possibility to upstream some patches if necessary. What this internship will offer you: • Gain practical experience in HPC architectures and software optimization. • Develop expertise in parallel programming, SVE vectorization and performance analysis. • Strengthen your skills in debugging, testing and open-source software development. • Collaborate with experienced engineers on real-world technical challenges. 🔍What makes you a good match for the role • Final-year engineering student or Master's degree student in Computer Science, Software Engineering, HPC or a related field. • Strong interest in processor architectures, parallel programming and software optimization. • Analytical, rigorous and proactive, with good problem-solving skills. • Ability to work independently and collaboratively in an international environment. • Good understanding of C/C++ (Fortran is a plus). • Knowledge on MPI, OpenMP, SIMD. • Knowledge of CPU architecture (ARM architecture is plus). • Basics of CI and Linux. 📍 Location -> Maisons-Laffitte Department Performance Engineering Role Compiler, Libs and Tools Location Maisons-Laffitte About SiPearl SiPearl is the European fabless designer of sovereign secure high-performance energy-efficient CPUs for HPC, AI and data centres.
