In today's scientific research, computational science, experimental science, and theoretical science are listed as three scientific methods. With the rapid development of computing technology and the maturity of scientific theoretical models, high-performance computing technology has been in the fields of science, engineering, and society. More and more applications. High performance computing is an indispensable research tool in the fields of geology, meteorology, surveying and mapping science, celestial space, condensed matter physics, high energy physics, computational chemistry, molecular biology, gene sequencing, and materials science.
High-performance computing technology is widely used, more efficient, and easy to use.
Based on the current theoretical development, universities and research institutions can use high-performance computing to observe more detailed levels than experimental phenomena, or theoretical simulations of experimental observations that are currently expensive or impossible to implement, thus helping to explain experimental results and understand natural laws. Further guide the experimental process and greatly improve the efficiency of the experiment.
The University of Nottingham Ningbo is the first Chinese-foreign cooperative university approved by the Ministry of Education to introduce world-class universities. It is also the world's top university ranked among the top 100 universities in the world. The University of Nottingham Ningbo combines the advantages of the University of Nottingham with the actual needs of China's social and economic development, and introduces a series of internationally renowned degree programs. Its scientific strength and level are also at the forefront in China. In order to further enhance the academic advantages and solve the difficulties of school teachers' scientific research and teaching, the Information Technology Service of the University of Nottingham Ningbo, China, built a school-level high-performance computing platform and applied high-performance computing cluster technology to the civil engineering. In the disciplines of engineering, chemistry and environment, machinery, materials and manufacturing engineering, the research and teaching strength of their respective disciplines has been greatly enhanced.
Three steps to create a unique advantage for high-performance computing platforms
In response to the needs of high-performance computing platform construction, the University of Nottingham Ningbo, China, teamed up with Huawei to create a school-level high-performance computing platform based on “hardware + software + servicesâ€. The school made detailed planning for the top-level design of the computing platform, integrated software and hardware resources, and built an end-to-end high-performance computing management platform architecture and system to provide a stable and reliable experimental environment for each department, solving scientific research and daily life. The need for high performance computing systems in teaching. The entire system has several advantages:
Hardware architecture:
Software Architecture:
Ningbo University of Nottingham High Performance Computing Management Platform Solution
First of all, the University of Nottingham Ningbo High Performance Computing Management Platform architecture is on the Huawei E9000 Hyper-converged blade server underlying infrastructure platform. The advantage is that the two-way computing nodes, GPU computing nodes and Infiniband switching network modules are interspersed in a single-frame blade. Effectively increased resource density. In addition, with 56Gb/s Infiniband network and OceanStor V3 storage array, the performance bottleneck of the hardware layer is completely eliminated.
On the high-performance infrastructure platform, the University of Nottingham Ningbo uses the high-performance clustering software CHESS (Clustertech HPC Environment Software Stack) developed by Lianke to manage cluster resources, which can turn discrete servers into a complete set of HPC cluster systems and realize cluster resources. Unified deployment, management, monitoring, scheduling, and reporting, this series of rich and easy-to-use features allows platform administrators to use CHESS to achieve more efficient and convenient platform resource management, and to quickly respond to the research and teaching needs of each department. .
Finally, in order to further improve the ease of use of the platform, the University of Nottingham Ningbo has made a personalized and innovative design for the high-performance computing platform in the areas of user management and application scenarios, and unified management of cluster user accounts and school user accounts, and targeted users. Each application needs to help users complete the compilation and follow-up of software, and the preparation of job scripts, which greatly facilitates the use of teachers and students in schools, makes the research of teachers and students easier, focuses on scientific research, and accelerates the improvement of scientific research efficiency. .
From the underlying hardware platform, to resource management to the specific needs of users and applications, the University of Nottingham Ningbo, together with Huawei and Lianke, has created a new generation of innovative high-performance computing platform to serve the school with one-stop turnkey projects. teaching. Through this turnkey project, the college administrator can fully control the system state, realize unified management and scheduling of resources, and at the same time optimize the details of software compilation and scripting, the school teachers and students can deploy the experimental environment in a shorter time. In the end, teachers and students will be freed from the complicated experimental environment and put more energy into scientific research.
After the completion of the construction of the high-performance computing cluster at the University of Nottingham, Ningbo, the floating point calculation capability of the linpack test cluster reached more than 85% of the theoretical calculation peak. This turnkey project has played a very good role in promoting the research and scientific research of the school. It has been recognized and affirmed by the teachers and students of the school, and finally the school research and scientific research calculations are accelerated.
