About SiPearl

Founded in 2019 with the support of the European Union SiPearl embodies Europes dream of mastering the technological heart of its supercomputers: the microprocessor.

SiPearl is building Rhea the highperformance lowpower European microprocessor dedicated to supercomputing and AI inference.

This new generation of microprocessors will first target EuroHPC Joint Undertaking ecosystem which is deploying worldcl supercomputing infrastructures in Europe for solving major challenges in medical research artificial intelligence security energy management and climate with a reduced carbon footprint.

SiPearl is working in close collaboration with its 30 partners from the European Processor Initiative (EPI) consortium leading names from the scientific community supercomputing centers and industry which are its stakeholders future clients and endusers.

SiPearl employs more than 190 people in:

  • France (MaisonsLaffitte Grenoble My Sophia Antipolis)
  • Germany (Duisburg)
  • Spain (Barcelona)
  • and Italy (Bologna)

About the Internship

In this role you will work closely with Olivier Deprez our System & Software Architecture Team Leader

What a regular day at the job might look like

  • Recent ARM arch based HPC CPUs are based on coherent mesh network (CMN) to support communication between the Cores the memory and the other units (Storage PCIe). This mesh network is the principal physical link between those units transporting data with high bandwidth. On the top of the CMN a transport layer called CHI is used to transmit flits of data from one point to the other. The CMN is a critical part when considering performances on HPC context.
    Performance ysis is an important topic in HPC because it is the first step to perform when optimizing and accelerating a specific program/application for a specific architecture. Different odologies and technics exist for Performance ysis and there are often based on specialized kind of hardware unit called (Performance Monitoring Unit) Core PMU. The Core PMUs are monitoring events of the CPU cores itself. Counting and aggregating those events over multiple cores gives a first level of ysis odologies. For example topdown odology is based on Core PMUs. The CMN itself is also equipped with different kind of PMUs however no clear odology exists to exploit CMN PMUs.
    The goal of the internship is to develop a odology for CMN.

What would make you succeed in this role

  • A good understanding of modern CPU architecture
  • Good learning capacity
  • Good writing ss
  • Familiar with Linux dev environment & tools
  • Familiar with essential dev tools like gcc git make cmake
  • Familiar with C language
  • Fluency in English is a prerequisite for success in this role as effective communication in English is essential for collaboration and ensuring the seamless of responsibilities.

Experience in the following is a plus

  • Knowledges on ARM architecture
  • Knowledges on HPC
  • Knowledges on Benchmarking
  • Knowledges on CMN
  • Knowledges on performance optimization & profiling
  • Knowledges on ARM System & Software stack
  • Knowledges on ARM Applicative CPU architecture

  • Dear candidate even if you consider you do not fulfill all the qualifications mentioned above please still apply and share with us why you believe you would be a good fit.
