Optimizing Polars Expressions: Core Techniques for Accelerating String Processing with SIMD Instruction Sets When I first used Polars to clean up millions of usernames, I stared at the progress bar on the screen in disbelief—what originally took 30 seconds suddenly dropped to 3 seconds. The magic behind this is the perfect combination of SIMD instruction … Read more
Today, let’s talk about a powerful Python library – Pillow-SIMD. The name might sound a bit unfamiliar at first, but don’t worry, let me explain. You may already know Pillow, which is a commonly used image processing library in Python that helps us open, edit, and save various image files. Pillow-SIMD, on the other hand, … Read more
In 1966, Micheal Flynn classified computer architectures based on the concepts of instruction and data streams, known as Flynn’s taxonomy. Flynn categorized computers into four basic types as follows: Single Instruction Single Data (SISD) systems Single Instruction Multiple Data (SIMD) systems Multiple Instruction Single Data (MISD) systems Multiple Instruction Multiple Data (MIMD) systems Single Instruction … Read more
Click the “blue text” above to follow us Have you ever had this experience? You wrote a program to process a large amount of data, went to make a cup of coffee, and came back to find the program still “buzzing” away. Anxiously waiting, you finally conclude: the performance is lacking! Especially when dealing with … Read more
Click the “blue text” above to follow us Late at night, the laboratory is brightly lit. Old Wang stares at the screen, frowning. “This FASTA sequence alignment is way too slow! How long will it take to align a set of human genomes?” This scene seems familiar, right? In the field of bioinformatics, sequence alignment … Read more
