LINEAR LOG-NORMAL ATTENTION WITH UNBIASED CONCENTRATION

Transformer models have achieved remarkable results in a wide range of applications. However, their scalability is hampered by the quadratic time and memory complexity of the self-attention mechanism concerning the sequence length.

Non-magnetic four-port electronic circulators based on 90∘ non-reciprocal phase-shifters

This paper presents a family of four-port electronic circulators adhering to a new topology symmetry that enables linear, low-loss transistor-based circuit implementations. The underlying principle of operation employs a property of the 90∘ non-reciprocal phase shifter (NRPS) derived in this article. Under...

Rotation Invariant Quantization for Model Compression

Post-training Neural Network (NN) model compression is an attractive approach for deploying large, memory-consuming models on devices with limited memory resources. In this study, we investigate the rate-distortion tradeoff for NN model compression.

libFastMesh: An optimized finite-volume framework for computational aeroacoustics

This paper presents an optimized framework for simulating aeroacoustic flow on unstructured meshes. The libFastMesh (LFM) framework is based on a low-dissipation finite–volume discretization, together with high-order explicit time integration, for direct computation of aeroacoustic fields. These methods were previously...

Hyper Burst Buffer: A Lightweight Burst Buffer I/O Library for High Performance Computing Applications

The growth of computing power of large-scale HPC clusters has lead to the need for large high-bandwidth I/O systems. However, directly writing the large and bursty datasets to centralized parallel file systems can raise significant I/O contention issues on storage...
