Comparison of Communication Based on Traditional Ethernet and RDMA Technology
This article is reprinted from Zhihu Column: 2. Comparison between communication based on traditional Ethernet and RDMA technology, author: Savir. Traditional Ethernet provides a Socket interface as an API to upper-layer applications, while the RDMA protocol stack provides a verbs interface to the upper layer. There are significant differences between these two communication methods in the process of data reaching the memory space of the remote user from the local user's memory space. This article aims to explain to readers why we should use RDMA technology by comparing these differences.
Compile and Install UCX 1.15.0 and OpenMPI 5.0.0: A Comprehensive Guide
Unified Communication X (UCX) and Open Message Passing Interface (OpenMPI) are two indispensable components in the field of high-performance computing. UCX provides an efficient set of low-level communication libraries, optimizing hardware resource utilization, while OpenMPI is a message passing interface widely used in parallel computing tasks. This article will provide detailed guidance on how to compile and install UCX version 1.15.0 from source code and the compatible OpenMPI version 5.0.0.
GCC-13.2.0 Compilation and Installation
GCC-13 is a major update. In this version, GCC's static analyzer continues to improve, with more C23 and C++23 features, and supports many new x86_64/RISC-V/AArch64 processors. To promote the use of the new C++ standards instead of always writing C++17 or even C++11, I decided to compile and install GCC-13.2.0 to experience the new C++ standards.
