Notes: Pure - Improving Message Passing to Better Utilize Intra-Node Shared Memory
Pure is a new programming model and runtime system designed to fully leverage shared memory within nodes in environments based on the Message Passing Interface (enhancing the utilization of idle core capabilities through tasks). Pure utilizes shared memory in two ways: (1) allowing ranks to steal work from each other while waiting for messages to arrive; (2) enabling high-performance message passing and collective operations between processes within a node using efficient lock-free data structures. Researchers evaluated the key message passing and collective features of Pure through micro benchmark tests and demonstrated that in CoMD molecular dynamics and miniAMR adaptive mesh refinement applications, Pure can achieve up to 2.1x application acceleration when scaling to 4096 ranks.

This article aims to explore and recommend a series of professional and widely used scientific charting tools, which have become indispensable work partners for researchers due to their powerful features and flexibility.
RDMA Basic Service Types
This article is reprinted from Zhihu Column: 5. Basic Service Types of RDMA, Author: Savir. Just like the UDP and TCP in the transport layer of the TCP/IP protocol stack, RDMA technology also specifies service types for different scenarios, with each type emphasizing different aspects of reliability and speed. This article introduces the characteristics and application scenarios of 4 main service types.
