The Python Pillow library is quite familiar to everyone, as it is a great helper for image processing. However, it can be a bit slow when dealing with large images. Today, let’s talk about how to speed it up using Pillow-SIMD and make it fly! ## What is SIMD? SIMD, or Single Instruction Multiple Data, … Read more
In a large e-commerce project, we need to process hundreds of thousands of product images daily for scaling, cropping, and format conversion. When using the regular Pillow library, image processing speed became a serious performance bottleneck. Until we discovered Pillow-SIMD, this “magic tool,” which boosted image processing speed by an astonishing 30 times, significantly reducing … Read more
ClickHouse has done very detailed work at the computing layer, maximizing hardware capabilities to enhance query speed. It implements various important technologies such as single-machine multi-core parallelism, distributed computing, vectorized execution with SIMD instructions, and code generation. Multi-Core Parallelism ClickHouse divides data into multiple partitions, each partition is further divided into multiple index granularities, and … Read more
JSON documents are ubiquitous on the Internet, and servers spend a considerable amount of time parsing these documents. We aim to accelerate the parsing of JSON itself as much as possible using commonly used SIMD instructions while performing full validation (including character encoding). Performance Results Simdjson uses fewer instructions than the state-of-the-art parser RapidJSON by … Read more
Author | SatanWoo SIMD is a common computing method that processes multiple data points with a single instruction. This article serves as an introduction to SIMD, starting with a simple understanding of its usage and concepts. Meaning of SIMD SIMD stands for Single Instruction Multiple Data. In brief, it refers to the ability to process … Read more
Partition-based SIMD processing and its application in columnar database systems The Single Instruction Multiple Data (SIMD) paradigm is considered the core principle for optimizing query processing in columnar database systems. So far, only LOAD/STORE instructions are deemed efficient enough to achieve the expected acceleration, and it is believed that GATHER/SCATTER operations should be avoided as … Read more

Since the introduction of the Cortex-A72 with out-of-order triple issue in February 2015, ARM launched the Cortex-A73 core in May this year, claiming that this core achieves the same or even better performance than the Cortex-A72 in its out-of-order dual-issue design. Is the Cortex-A73 really that impressive? Issue Width Is Not Everything As a product … Read more
Smartwatches have become familiar gadgets for most users today, and the entry price for such products is low enough that one can often buy mainstream models from leading brands for just a few hundred yuan. From the perspective of user habits, using smartwatches to check notifications, make calls, or track health metrics (especially heart rate, … Read more
Proteus Motion is a unique 3D resistance training device, primarily composed of a rotating base and a retractable metal arm. Users grasp the handle on the metal arm and perform training movements while overcoming the magnetic resistance applied by the arm across multiple planes of motion, thus engaging in strength-speed training. Proteus Motion not only … Read more
