We will implement the leader election algorithm in a simple way, without any optimizations. We will explain all detailed explanation about raft paper in another posts. Our basic code structure is provided by 6.824. So we will not provide the code here, but we will explain the main idea of the leader election algorithm.</p>https://blog.saltfish.org/posts/usage-of-entry-level-gpu/Thu, 12 Feb 2026 18:16:43 -0500https://blog.saltfish.org/posts/usage-of-entry-level-gpu/<p><strong>Our chat system collapsed under 20 concurrent requests</strong></p> <p>Currently, I&rsquo;m working on a RAG(Retrieval Augmented Generation) project, while most of the process is done by calling api, the only computation intensive part is the reranking process, which is a method to rank the retrieved documents based on their relevance to the query. In this step we called <code>BAAI/bge-reranker-v2-m3</code> model locally.</p>
