Jacob Wahlgren

My research is focused on next-generation memory in large-scale parallel computing. Advances in this area can expand the possibilities of computing by improving performance and enabling efficient energy use. My work spans from hardware and architecture to operating systems and applications. In particular, I have explored how rack-scale memory pooling can make high-performance computing more efficient and affordable.

I am part of the ScaLab research group led by Prof. Ivy Peng.

My research interests include:

• Disaggregated memory
• Tiered memory
• High-performance computing
• Computer architecture
