HPC Newsletter 1701
Dear colleagues,
We would kindly ask you to grant us 15 minutes of your time by filling out the bwHPC survey: https://evasysw.uni-stuttgart.de/evasys/online.php?p=bwhpc.
Welcome to the first Freiburg HPC newsletter in 2017. Since the last newsletter was published, the NEMO Cluster-Beirat (advisory board) has been established. Additionally, a technical advisory board was conceived to discuss practical issues with deputies of the most active NEMO workgroups. We have seen a steady increase in approved Rechenvorhaben for NEMO and the other bwForClusters. Consequently, the workload on NEMO is now quite often at 100% and jobs will get queued instead of being immediately executed.
Best wishes, your HPC team

bwHPC survey
We would kindly ask you to grant us 15 minutes of your time by filling out the bwHPC survey: https://evasysw.uni-stuttgart.de/evasys/online.php?p=bwhpc. This is important feedback for future plans regarding high performance computing resources in Baden-Württemberg. Further projects and investment decisions will surely reference the results of this survey. (Read more)
NeuroCampus/ViCE Workshop on Virtualized Research Environments
On 08.06.2017 the Bernstein Center Freiburg will host a joint workshop of the NeuroCampus project and the ViCE project regarding Virtualized Research Environments. There will be short focus presentation, followed by discussions and hands-on-sessions on the federated services bwCloud, bwLehrpool and bwHPC offered by the computing center and it's partners. Please forward this information to colleagues who might be interested. (Read more)
Journées lycéens 2017
On 18.05.2017, in the framework of Eucor and Neurocampus, school students from Strasbourg and Freiburg were invited to jointly attend scientific lectures to get an insight into potential fields for their future studies and work, with a special focus on and opportunities offered by the inter-regional cooperations in the upper rhine valley.

NEMO Cluster-Beirat and NEMO technical advisory board
The first two meetings of the NEMO Cluster-Beirat (advisory board) took place on 14.12.2016 and on 08.03.2017. Following the recommendations of the first meeting, an additional NEMO TAB (*technical* advisory board) was established to discuss practical issues with deputies of the most active NEMO workgroups. The first two meetings of the NEMO TAB took place on 17.02.2017 and 03.03.2017. The main topics were related to fairshare and accounting and the upcoming NEMO extension.
NEMO status and statistics
NEMO is now quite often under full load and jobs are getting queued. While it may be inconvenient for users that their jobs do not get executed immediately, this is the desired target state for a high performance computing system.
We advise users to check the status and statistics of NEMO. For more detailed statistics on our monitoring server: https://cloud.nemo.uni-freiburg.de/user (login required). (Read more)
End of support for Matlab Distributed Compute Server (MDCS)
The state wide licence for Matlab is expiring next year (31.03.2018). There are negotiations for a renewal taking place, but the outcome is not certain. As an immediate consequence of the current situation, usage of the Matlab Distributed Compute Server (MDCS) is deprecated and only limited support is provided for legacy installations. (Read more)
