Transcoding Unicode Characters with AVX-512 Instructions
Software: Practice and Experience, 2022 AbstractIntel includes in its recent processors a powerful set of instructions capable of processing 512‐bit registers with a single instruction (AVX‐512). Some of these instructions have no equivalent in earlier instruction sets. We leverage these instructions to efficiently transcode strings between the most common formats: UTF‐8 and UTF‐16. With our

Scalability analysis of AVX-512 extensions [PDF]
The Journal of Supercomputing, 2019 Energy efficiency below a specific thermal design power (TDP) has become the main design goal for microprocessors across all market segments. Optimizing the usage of the available transistors within the TDP is a pending topic. Parallelism is the basic foundation for achieving the exascale level.

Implementation of a vectorized Quicksort using AVX-512 intrinsics [PDF]
, 2021 Jahrzehntelang wurden Verbesserungen der Rechengeschwindigkeit erreicht, indem die Taktfrequenz der CPU erhöht wurde. Im Laufe der letzten Jahre wurde dieser Mechanismus durch physikalische Einflüsse gebremst. Daher müssen moderne Single-Thread-Anwendungen stärker CPU-Funktionen ausnutzen, um von den Fortschritten neuer Prozessorgenerationen zu ...

SeqMatcher: efficient genome sequence matching with AVX-512 extensions [PDF]
The Journal of SupercomputingAbstract The recent emergence of long-read sequencing technologies has enabled substantial improvements in accuracy and reduced computational costs. Nonetheless, pairwise sequence alignment remains a time-consuming step in common bioinformatics pipelines, becoming a bottleneck in de novo whole-genome assembly.

Vectorized Falcon-Sign Implementations using SSE2, AVX2, AVX-512F, NEON, and RVV
Transactions on Cryptographic Hardware and Embedded SystemsFalcon, a NTRU-based digital signature algorithm, has been selected by NIST as one of the post-quantum cryptography (PQC) standards. Compared to verification, the signature generation of Falcon is relatively slow. One of the core operations in signature
