Offer Description

The university of Bordeaux is a great dynamic and responsible university that cares about the well-being of its staff. Joining us means working in a privileged environment within a particularly diverse and open professional community, benefiting from welcome and inclusion schemes, training and internal mobility. It means participating in an academic, scientific and human adventure. It means committing to meeting the challenges of the 21st century.

Join the Astrophysics Laboratory of Bordeaux ( LAB ) – of the University of Bordeaux!

Located on the scientific campus, the LAB is a Research Unit under the supervision of the CNRS and the University of Bordeaux. The LAB’s mission is to conduct research in the field of Universe Sciences, build the associated instrumentation, train students, for and through research and disseminate knowledge.

As part of the European project (Horizon Europe) RADIOBLOCKS , we are recruiting a Research Engineer in software development W/M .

One of our main objectives is to deliver a library of components for the next-generation correlator technology. For that we will develop a collection of efficient, and/or high-performance signal processing building blocks exploiting commercially available hardware accelerator platforms. The most cost-efficient and energy-efficient way to build this correlator system is with FPGAs near the receivers, tensor-core-enabled GPUs for correlations, and an off-the-shelf (Ethernet) network switch in between. A cost-effective and energy efficient design can be achieved by proper codesign between FPGA, network, and GPU: the FPGAs must prepare data so that it can be switched on the network and can be consumed by the GPUs without additional overhead.

Main activities

You will be integrated into the 'Electronic Systems and Instrumental Computing' ( SE2I ) team, which comprises about 10 people. This team is responsible for the definition, design and monitoring of scientific instruments as part of instrumental projects for astronomy and astrophysics. It also has expertise in the field of high-throughput digitization and digital signal processing well known in the radio astronomy community. This expertise, mainly based on FPGA technologies, now includes CPUs and GPUs.

You will contribute, notably within the framework of the European project RADIOBLOCKS, to the development of a signal processing software chain, ranging from data reception via the 400 GbE protocol to real-time cross-correlation on the GPU.

Architecture and software development

• Architect and implement a high-performance real-time data processing pipeline from 400 GbE network interface cards to GPU memory
• Research and develop low-level, zero-copy data transport technologies, such as DPDK, RDMA, or NVIDIA DOCA DPA, to avoid unnecessary data copies through intermediate buffers
• Design and develop persistent CUDA kernels for real-time cross-correlation of multi-channel digitized signals, fully exploiting the massively parallel GPU architecture
• Work with FPGA developers to ensure seamless end-to-end data flow from digitizers to the GPU processing pipeline
• Develop real-time monitoring and visualization tools for correlation results, enabling continuous assessment of system stability and signal coherence
• Develop, unit test, and deploy functional, scalable, robust, and maintainable software
• Generate and maintain documentation of designed software and integrated systems
