Ollama: From Beginner to Advanced
This article focuses on introducing the basic concepts of Ollama and its notable advantages, including its open-source and free nature, ease of use, rich models, and low resource consumption. It then provides a detailed installation and usage guide, covering detailed installation steps for different operating systems and Docker environments, as well as how to download and run models. Additionally, the article introduces how to deploy Ollama on HPC clusters and how to create a local code completion assistant by integrating IDE plugins.
RDMA: Address Handle
This article is reprinted from Zhihu column: 8. RDMA Address Handle, author: Savir. AH stands for Address Handle. In service types such as UD, the local end uses AH to specify the remote node.
RDMA: Protection Domain
This article is reprinted from Zhihu Column: 7. RDMA Protection Domain, author: Savir. To isolate various RDMA resources, the protocol introduces the concept of PD. PD stands for Protection Domain, which "groups" related software resources together, and resources between different protection domains cannot access each other.
RDMA: Memory Region
This article is reprinted from Zhihu Column: 6. RDMA Memory Region, Author: Savir. The essence of network communication is the migration of data in storage media, and RDMA manages memory through MR. MR is a special memory region, and this article introduces its concept and function.
Record: Install Intel® OneAPI-2024.0
OneAPI is an open and standards-based specification that supports multiple architecture types, including but not limited to GPU, CPU, and FPGA. The specification has direct programming and API-based programming paradigms. Intel® OneAPI is a software suite that includes various tools and libraries to support the OneAPI specification. This article documents the process of installing Intel® OneAPI-2024.0 on CentOS 7.6.
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.
Scientific Research Chart Drawing
In scientific research, precise and expressive data visualization is a crucial step. 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.
