| Aug 27, 2024 | 🎉 I’m happy to announce that the paper Exploring GPU-to-GPU Communication: Insights into Supercomputer Interconnects have been accepted at SC ‘24. The paper focuses on GPU-GPU interconnect. We analyzed three top-10 supercomputers, on up to 4k NVIDIA and AMD GPUs, offering valuable insights to architects, researchers, practitioners, and developers. The paper is the outcome of a fruitful collaboration with NVIDIA, Cray HPE, ETH Zurich, CINECA, University of Trento, Vrije Universitiet, and University of Antwerp. You can find a preprint here. |
| May 2, 2024 | 🎉 I’m happy to announce that the paper OSMOSIS: Enabling Multi-Tenancy in Datacenter SmartNICs have been accepted at USENIX ATC ‘24. OSMOSIS is a resource manager for SmartNICs to support multi-tenancy with low overhead. |
| Apr 4, 2024 | 🎉 I’m happy to announce that a new paper have been accepted at HPDC ‘24. The paper introduces a performance model and new algorithms for reduce and allreduce on the Cerebras Wafer-Scale Engine (WSE), a novel architecture optimized for machine learning workloads. The new algorithms outperform the current vendor solutions by more than 3x. |
| Feb 15, 2024 | 👨🏫 In partnership with the University of Trento and CINI, we will host in June a summer school focused on High-Performance Computing (HPC) (https://hpc-summer-school-24.disi.unitn.it/). I’ll be giving two lectures on interconnection networks and the process of writing HPC papers. If you’re interested, feel free to join. |
| Dec 11, 2023 | 🎉 I’m happy to announce that two papers have been accepted at NSDI ‘24. The first one is about a new algorithm for allreduce on multidimensional torus networks that improves performance up to 3x compared to state-of-the-art algorithms (you can find a preprint here). The second one is on the design, implementation, and evaluation of the first-ever Slim Fly network deployment (here). |
| Oct 21, 2023 | 🎉 Our paper “Canary: Congestion-Aware In-Network Allreduce” has been accepted for publication on Future Generation Computer Systems (FGCS). You can find a preprint here. |
| Jul 24, 2023 | 🎉 Our HammingMesh paper, the result of a collaboration between ETH Zurich and Microsoft, has been invited to appear in Communications of ACM (CACM) Research Highlights. |
