Sequence alignment is a fundamental and often time-consuming step in genomic data analysis. Typically, it adheres to the seed-and-extension paradigm and numerous accelerator-based approaches have been proposed to optimize either of the kernels. However, these approaches often increase costs and contribute minimally to the overall alignment process. To address this, we have designed an optimized full pipeline, FastBWA, which seeks to enhance performance while keeping costs low and explores the potential of CPU computing resources. Our implementation demonstrates that FastBWA achieves up to 2.5× and 1.8× in end-to-end alignment throughput compared to BWA-MEM and its newer version, BWA-MEM2.

Chiral multifold fermions in solids exhibit unique band structures and topological properties, making them ideal for exploring fundamental physical phenomena related to nontrivial topology, chirality, and symmetry breaking. However, the challenge of obtaining clean, flat surfaces through cleavage has hindered the investigation of their unique electronic states. In this study, we utilize high-resolution angle-resolved photoemission spectroscopy and density functional theory calculations to investigate the low-energy electronic structure of the cleavable single-crystal PdSbSe. Our combined experimental and theoretical analysis reveals the presence of multifold-degenerate fermions within this chiral crystal. We also observe multiple chiral Fermi arc surface states and spin-splitting behavior in the associated bulk bands. These findings provide unique insights into chiral, multifold fermionic states in easily cleavable crystals and offer a robust platform for further research into their unique electronic properties and potential applications in novel electronic devices.

Transmission Control Protocol (TCP) congestion control is a fundamental mechanism in the Internet that maintains network stability and performance by adjusting the sending rate of connections. Recently, Deep Reinforcement Learning (DRL) methods have shown superior performance over traditional expert-designed solutions. However, the DRL policies are often represented by black-box neural networks, they lack interpretability, making verification challenging and requiring excessive floating-point computation. This work introduces a novel approach, Programmatic reinforcement learning for Congestion Control (ProCC), designed to discover a program as a control policy from scratch autonomously. Programs in ProCC include branching structures (e.g., if blocks and if-else blocks), conditions and actions. However, directly optimizing such program structures is challenging due to their discrete non-differentiable nature, and the program space grows exponentially as the depth increases. To address this issue, ProCC defines a Domain-Specific Language (DSL) and program transformation rules, enabling the construction of a program search graph where similar programs are closer in proximity. Subsequently, ProCC employs Monte Carlo Tree Search (MCTS) to efficiently explore the discrete space and obtain promising programs. Extensive experiments conducted in multiple simulated environments demonstrate that ProCC is adaptive and consistently performs well under varying network conditions. The learned program's performance surpasses that of state-of-the-art DRL agents, and more importantly, the generated policies are concise, transparent, and computationally efficient. © 2025 Copyright held by the owner/author(s).

High-Level Synthesis (HLS) enables software engineers to create intricate digital circuit designs using high-level languages like C/C++. While HLS tools can perform functional verification using C/C++ simulation, it is harder to verify that the generated RTL is also correct. This problem is exacerbated for designs which include HLS-generated IPs, such as PCIe or DDR interfaces, or hand-written RTL. While it is possible to perform cycle-accurate verification using C/RTL co-simulation, conventional methods are both slow and typically only focus on unit-level verification which can make it harder to identify the root cause of a bug. To improve hardware verification, we propose Hercules: a novel method to efficiently verify HLS designs while preserving fine-grained debugging capabilities. HLS-generated hardware and corresponding C/C++ software models are run simultaneously on the FPGA’s programmable logic and hardened processors respectively. We compare both results of the hardware and software, and also compare internal signals with the help of the automatically generated probes to identify bugs and their root causes. This capability is embedded within a tool that takes hardware snapshots, meaning to debug the design we can recreate a software simulation from a point shortly before where the bug occurred. With Hercules, we have performed verification quickly over large benchmarks. This has helped us find HLS errors closer to their root cause than existing tools, making it easier to debug, as well as identify real issues in existing benchmarks and the Vitis HLS tool which current state-of-the-art methods were unable to locate. Moreover, it achieves this quickly - over a set of HLS benchmarks Hercules achieves speedups with a geometric mean ranging from 1391× to 8060× compared to conventional software simulations. © 2025 Copyright held by the owner/author(s).
