NEMO Maintenance on 22.02.2017

The maintenance is prompted by a functional upgrade to the cooling system of the hosting environment. The downtime will be used to apply all pending software and hardware upgrades to NEMO.
When Feb 22, 2017
from 06:00 AM to 06:00 PM
Add event to calendar vCal

Nemo will be down for maintenance on 22.02.2017. The maintenance is prompted by a functional upgrade to the cooling system of the hosting environment. We will make good use of this externally triggered downtime by applying all pending soft- and hardware upgrades to NEMO. Job scheduling will be suspended during the maintenance. Login and access to your files will not be possible during the maintenance.

You can submit jobs until the downtime starts (22.02.2017, 06:00 AM). Please note that jobs projected to finish after the downtime starts will be blocked. Your jobs should run after the downtime is complete.

Intel Xeon Phi x200 (Knights Landing): Performance Impressions and Best Practices

Speaker: Hans Pabst, Application Engineer for High Performance and Throughput Computing

Subtitle: Case study focusing on Quantum Espresso and CP2K

Abstract: This presentation gives a brief overview and reference of Intel Xeon Phi x200 family (codenamed Knights Landing or KNL), and thereby focuses on ISA-level enhancements when compared to the previous generation of Intel’s Manycore Architecture. The talk gives special focus on Xeon Phi’s NUMA clustering and how to take advantage of the High Bandwidth Memory portion (with and without code changes). For the two application cases (physics domain), the presentation walks through five very basic steps of getting an application ready for Knights Landing: (1) building an optimized application, (2) selecting the cluster/memory mode, (3) process pinning, and thread affinitization, (4) performance profiling, and (5) code modernization and optimization.


Tesla P100 GPU and DGX-1 Deep Learning Appliances

Speaker: Ralph Hinsche (Nvidia), Business Development Manager

Abstract:The binAC cluster in Tübingen, running on Tesla GPUs, is a step to accelerated computing and deep learning applications. This tech talk gives a short overview how the binAC cluster is built and continues with an outlook to the Tesla P100 platform and its performance features.




Inauguration NEMO and BinAC

With the bwForCluster BinAC (in Tübingen) and bwForCluster NEMO (in Freiburg) about to become operational, the bwHPC initiative has reached another milestone.
When Jul 14, 2016
from 03:00 PM to 07:00 PM
Where Freiburg, Otto-Krayer-Haus
Add event to calendar vCal

All four bwForClusters and the bwUniCluster will be available for researchers from Baden-Württemberg and the innovation circle is thus completed. To celebrate this, the official inauguration of both bwForClusters will take place in Freiburg on July 14th. You are cordially invited to join the event.

The inauguration will take place in the Otto-Krayer-Haus and the Rechenzentrum in Freiburg on July 14th.

There will be opportunities to talk to the colleagues from the other bwHPC-C5 competence centers. 

Back-to-back with the bwForCluster inauguration event, the first user assembly for the bwForCluster NEMO is going to be held in the late morning from 10:30 on July 14th.
