Introduction In the field of high-performance computing, parallel programming is crucial for fully leveraging the performance potential of modern computer hardware, especially multi-core processors and distributed computing clusters. OpenMP and MPI are two widely used parallel programming models, suitable for shared memory and distributed memory systems, … Read more
Why Are Compilers So Critical? On resource-constrained embedded platforms, compilers are not only responsible for translating source code into machine instructions but also undertake multi-level optimization tasks: Code Optimization and Size Reduction: Through function inlining, loop unrolling, constant propagation, and link-time optimization (LTO), firmware performance is enhanced and size is minimized. Hardware-Related Parameter Configuration: By … Read more
The Rust compiler is renowned for its ability to optimize code performance and manage memory, thanks to its borrow checkers. Rust code is compiled using the official compiler <span>rustc</span>, which utilizes LLVM as its backend to optimize and convert high-level Rust code into low-level machine code. However, a recent alternative has emerged called gccrs, which … Read more

Introduction First of all, I believe that foundational knowledge in computer science is timeless, while trendy “practical skills” may quickly become obsolete. This is why, during the major selection process in my sophomore year, I chose the Computer Science and Technology major instead of other flashy fields. In my junior and senior years, when studying … Read more
