HCCL: Collective Communication for Meta Training and Inference Accelerators
Wesley Bland, Tiago Antunes, Lars Paul Huse +63
We present HCCL, a collective communication library co-designed with Meta's MTIA 300 accelerator, the first Meta chip to integrate backend networking directly on chip package. MTIA…
Resilient AI Supercomputer Networking using MRC and SRv6
Joao Araujo, Alex Chow, Mark Handley +47
Tail latency dominates the performance of synchronous pretraining jobs when running at very large scales. We describe a three-pronged approach: (1) a new RDMA-based transport proto…
Collective Communication for 100k+ GPUs
Min Si, Pavan Balaji, Yongzhou Chen +36
The increasing scale of large language models (LLMs) necessitates highly efficient collective communication frameworks, particularly as training workloads extend to hundreds of tho…
Quantum optical neural networks
Gregory R. Steinbrecher, Jonathan P. Olson, Dirk Englund +1
Physically motivated quantum algorithms for specific near-term quantum hardware will likely be the next frontier in quantum information science. Here, we show how many of the featu…
High-rate field demonstration of large-alphabet quantum key distribution
Catherine Lee, Darius Bunandar, Zheshen Zhang +6
Quantum key distribution (QKD) exploits the quantum nature of light to share provably secure keys, allowing secure communication in the presence of an eavesdropper. The first QKD s…
Quantum transport simulations in a programmable nanophotonic processor
Nicholas C. Harris, Gregory R. Steinbrecher, Jacob Mower +9
Environmental noise and disorder play critical roles in quantum particle and wave transport in complex media, including solid-state and biological systems. Recent work has predicte…
Quantum Logic with Interacting Bosons in 1D
Yoav Lahini, Gregory R. Steinbrecher, Adam D. Bookatz +1
We present a scheme for implementing high-fidelity quantum logic gates using the quantum walk of a few interacting bosons on a one-dimensional lattice. The gate operation is carrie…
Towards High-Fidelity Quantum Computation and Simulation on a Programmable Photonic Integrated Circuit
Jacob Mower, Nicholas C. Harris, Gregory R. Steinbrecher +2
We propose and analyze the design of a programmable photonic integrated circuit for high-fidelity quantum computation and simulation. We demonstrate that the reconfigurability of o…
Cross-Layer Design to Maintain Earthquake Sensor Network Connectivity After Loss of Infrastructure
Greg Steinbrecher
We present the design of a cross-layer protocol to maintain connectivity in an earthquake monitoring and early warning sensor network in the absence of communications infrastructur…
