Research Engineer – HPC memory systems (RE1)

Context And Mission
The Memory Systems group in the Computer Science Department at the Barcelona Supercomputing Center is offering a full-time research engineer position for a project that explores advanced memory systems for AI applications.

The performance of AI models is typically limited by the memory wall. In this project, we aim to (re)move this wall by designing memory systems tailored to the requirements of AI models. We will explore systems based on HBM, DDR, GDDR devices, and Compute Express Link (CXL) memory expanders. Additionally, we will consider near-data processing architectures that offload part of the CPU/GPU processing to the memory system.

The project is conducted in close collaboration with a major memory manufacturer. Most of the development will take place on high-end hardware products and industrial prototypes.

We strongly encourage applications from candidates interested in joining a research team with over a decade of experience in industrial projects with major hardware companies from the US, China, and Korea.

Key Duties
– Profiling and performance modeling of HPC applications running on high-end servers with advanced memory systems: HBM, DDR4/5, CXL memory expanders.
– Exploration of Processing in Memory for HPC and AI applications.
– Prototyping of industrial products and tools.
– Close interaction and reporting to industrial partners.
– Benchmarking and performance analysis of high-end hardware products and industrial prototypes.



– BSc, MSc or PhD in Computer Science
