NHR South-West

National High Performance Computing (NHR) Alliance Launches Scientific Conference Series

The first conference will take place on September 18-19 at the Zuse Institute in Berlin. The scientific conference series with annually changing focal topics is intended to promote the exchange of scientists on HPC use. This year's inaugural NHR conference will focus on atomistic simulation, life sciences and agent-based simulation.

With top-class keynote speakers and further lectures on this year’s scientific topics, the conference will provide the basis for a scientific exchange beyond disciplinary boundaries.

Keynote Speakers

  • Mohammed AlQuraishi, Columbia University New York
  • Rob Axtell, George Mason University College of Science
  • Helmut Grubmüller, MPI, Göttingen
  • Karissa Sanbonmatsu, Los Alamos National Laboratory

By presenting your research in a talk or poster, you are invited to initiate discussions with other scientists. NHR is made for science and so you are asked to provide impetus to make NHR meet your needs. Consulting, and operator staff will participate in the program, and there will be lots of opportunities for one-on-one meetings as well as panel discussions.

Since the end of 2021 the JGU is part of the transnational consortium of the national high-performance computers (NHR) South-West. Aside from Mainz other members include the Rhineland-Palatinate technical university of Kaiserslautern-Landau, the Goethe university of Frankfurt and the university of the saarland. Throughout Germany, scientists focusing on high-energy physics, condensed matter physics and life science can use MOGON NHR South-West for their research.

New High-Performance Computer inaugurated: MOGON NHR South-West

On March 13th, the new MOGON NHR South-West was inaugurated by Clemens Hoch, the Minister of Science and Health of the federal state Rhineland-Palatinate and Prof. Dr. Müller-Stach, Vicepresident for Research and young scientist at the Johannes Gutenberg University of Mainz (JGU). The association NHR South-West consists of the Johannes Gutenberg University of Mainz, the Rhineland-Palatinate technical University of Kaiserslautern-Landau, the Goethe University of Frankfurt and the University of the Saarland and since the end of 2021 one of nine centers for national high-performance computers (NHR) in Germany. Besides representatives of the JGU, guests from the three parter universities were also present.

The new HPC-System MOGON NHR South-West located in Mainz, expands the computing capacity of the transnational consortium and is available to research groups from all over Germany. For the new set up of the cluster the NHR South-West received 7.5 million euros from the federal-country-funding "national high-performance computer". With the financial resources an efficient System could be built in Mainz. Carsten Allendörfer, technical director of the Data Center (ZDV) was responsible for the set up togehter with the HPC-group of he ZDV. "After MOGON I and MOGON II we are happy to provide a cluster that scientists throughout Germany can use with the focus on high-energy physics, condensed matter physics and life science."

 

Markus Tacke, technical director of the HPC-Group, adds: "The nwe MOGON NHR South-West consits of 590 computing nodes, 75.000 CPU-cores and a main memory of 186 TB. Per nodes two AMD-processer are available (AMD EPYC 7713), per processor each time 64 cores."

Half-time in cluster set up for National High-Performance Computing (NHR)

With the inclusion of the NHR South-West in the National High-Performance Computing, the preparations for the installation of the new cluster at the Johannes Gutenberg University Mainz (JGU) also started. The working group for High-Performance Computing (HPC) at the Data Center (ZDV) has been working intensively on the conception and planning for the past few months, ordered the required hardware and had parts of the central server room converted for the cluster.

Preparation is everything

The future cooling of the cluster was initially the focus of the construction measures. The existing piping in the raised floor had to be extended so that the planned Direct Liquid Cooling system could dissipate the waste heat from the computing nodes in the future. Side coolers, which are located between the server racks, dissipate the heat from the remaining hardware using air circulation. The server racks and side coolers were delivered at the beginning of August and installed on site by our colleagues.

 

Also mounted and ready for use are the power distribution units that provide power to the hardware in the server racks. Furthermore, the various networks must be prepared for the upcoming deployment of the cluster. The HPC staff was able to lay the first foundations with the help of the ZDV network group by installing the switches of the management network and the first parts of the HDR-Infiniband network. The use of HDR-Infiniband, a special network interface standard, offers above all a very high transmission rate.

Outlook

Further hardware deliveries are scheduled by the end of the year: Components for the Direct Liquid Cooling system and the computing nodes themselves. As soon as the cluster is ready for operation, it will be available to researchers throughout Germany via the NHR South-West. Main topics in Mainz are: High Energy Physics, Condensed Matter Physics and Life Science.

About the NHR South-West

The NHR South-West is a cross-national consortium that includes JGU, the Technical University of Kaiserslautern, Goethe University Frankfurt and Saarland University. The goal is to benefit mutually from methodological expertise and computing capacity that is being developed.

Researchers from the four universities of NHR South-West can network more closely with other high-performance computing centers within the alliance and develop their technical and methodological competencies in High-performance computing in a targeted and coordinated manner. In this way, the advantages of High-performance computing can be made available to research and science in the long term.

In October 2021, the joint science conference of the federal and state governments decided to include JGU in the National Supercomputing Alliance.
