Self-deployed execution environment for high performance computing Research Articles

Mingtian SHAO, Kai LU, Wenzhe ZHANG

Frontiers of Information Technology & Electronic Engineering 2022, Volume 23, Issue 6, Pages 845-857 doi: 10.1631/FITEE.2100016

Abstract:

Traditional (HPC) systems provide a standard preset environment to support scientific computation.The standard preset environment can no longer meet these diverse requirements.SDEE provides an isolated and customizable environment (similar to a virtual machine) to the user.The user is the root user in this environment.The user develops and debugs the application and deploys its special dependencies in this environment

TEES: topology-aware execution environment service for fast and agile application deployment in HPC Research Article

Mingtian SHAO, Kai LU, Wanqing CHI, Ruibo WANG, Yiqin DAI, Wenzhe ZHANG

Frontiers of Information Technology & Electronic Engineering 2022, Volume 23, Issue 11, Pages 1631-1645 doi: 10.1631/FITEE.2100284

Abstract:

systems are about to reach a new height: exascale. is becoming an increasingly prominent problem. technology solves the problems of encapsulation and migration of applications and their . However, the image is too large, and deploying the image to a large number of compute nodes is time-consuming. Although the approach brings higher transmission efficiency, it introduces larger network load. All of these issues lead to high startup latency of the application. To solve these problems, we propose the topology-aware service (TEES) for fast and agile on HPC systems. TEES creates a more lightweight for users, and uses a more efficient topology-aware P2P approach to reduce deployment time. Combined with a split-step transport and launch-in-advance mechanism, TEES reduces application startup latency. In the Tianhe HPC system, TEES realizes the deployment and startup of a typical application on 17 560 compute nodes within 3 s. Compared to -based , the speed is increased by 12-fold, and the network load is reduced by 85%.

Intelligent data analytics is here to change engineering management

Jonathan Jingsheng SHI, Saixing ZENG, Xiaohua MENG

Frontiers of Engineering Management 2017, Volume 4, Issue 1, Pages 41-48 doi: 10.15302/J-FEM-2017003

Abstract: A great deal of scientific research in the world aims at discovering the facts about the world so that we understand it better and find solutions to problems. Data enabling technology plays an important role in modern scientific discovery and technologic advancement. The importance of good information was long recognized by prominent leaders such as Sun Tzu and Napoleon. Factual data enables managers to measure, to understand their businesses, and to directly translate that knowledge into improved decision making and performance. This position paper argues that data analytics is ready to change engineering management in the following areas: 1) by making relevant historical data available to the manager at the time when it’s needed; 2) by filtering out actionable intelligence from the ocean of data; and 3) by integrating useful data from multiple sources to support quantitative decision-making. Considering the unique need for engineering management, the paper proposes researchable topics in the two broad areas of data acquisition and data analytics. The purpose of the paper is to provoke discussion from peers and to encourage research activity.
