Apply for Computing Time by January 28th, 2020
[3465] Jan 13, 2020

The Scientific Board of the HLRN is inviting project proposals applying for computing time on the HLRN system.

The next deadline is January 28th, 2020, at 23:59.

Projects that need more computing time than 10,000 NPL resource units per quarter are invited to submit a project proposal ("Großprojektantrag") to the Scientific Board ("Wissenschaftlicher Ausschuss") of HLRN for the next quarterly review. Resources are allocated for one year starting April 1st, 2020, on a quarterly basis after review of the proposal (see the Application HowTo and the Scientific Board portal page). Notifications will be sent out around mid-March 2020.

In 2020 HLRN allocates about 135 million core hours per quarter (equivalent to about 60 million NPL per year) to successful proposals.
Please note: The project abstract has to be created in a specific format. The appropriate HLRN LaTeX template can be downloaded from the HLRN web page "required documents". The use of this template is required.

Please contact your HLRN project consultant before submitting the proposal.

HLRN-IV system Lise open for early adopters
[3463] Dec 19, 2019

We are glad to announce the immediate availablity of the HLRN-IV phase 2 system "Lise" in Berlin for user access.

Please note, that at this time only registered early adopters ("powerusers") are allowed to login. Registered early adopters have received additional information by email.

For an up-to-date schedule and further information about the HLRN-IV installation please see the web page at https://support.hlrn.de/home/view/NewsCenter/HLRN4News

Thank you for your continuing support and patience.

Lise ranks 40 on TOP500 List
[3458] Nov 21, 2019
On November 19th, 2019 the 54. edition of the TOP500 was revealed at the SC19 in Denver, Colorado. With 5,355.94 TFlop/s LINPACK Performance, the HLRN-IV System Lise in Berlin was ranked at 40th place worldwide and 5th in Germany.

The TOP500 is the list containing the 500 fastest supercomputers worldwide. It is released twice a year in June and November and measures computing power using the LINPACK Benchmarks.


Bye bye Konrad
[3434] Oct 16, 2019

The operation of the Berlin Cray system Konrad has now been stopped forever, making place for its successor, the HLRN-IV system Lise, which will be available for general user access in December.

In the last years, the HLRN-III systems Konrad and Gottfried helped the scientific community in North Germany and beyond to solve challenging problems. Since 2014 we provided 2 billion core hours in 2.6 million jobs. With the Cray architecture, we were happy to sustain an availability of more than 98% over the last years.

Thank you for using the HLRN-III resources!

See you on the HLRN-IV systems Lise and Emmy.

New GPU node in Göttingen
[3414] Sep 11, 2019
Dear users,

we are happy to announce that the first GPU node went into production in Göttingen today. The node (ggpu01) has the following hardware:
2 x Intel Skylake Gold 6148 CPUs (40 cores per node)
192 GB memory
1 x 480 GB solid-state disk
1 x Intel Omni-Path host fabric adapter
4 x NVIDIA Tesla V100 GPUs

This node will be a shared node for data pre- and postprocessing as well as machine learning. The CUDA and cuDNN libraries are installed on the node and a GPU accelerated TensorFlow environment has been added to the anaconda3/2019.03 module. More information on how to use the GPUs can be found in our documentation.

External target host handling revised, effective August 5.
[3394] Jul 29, 2019

Action required!

Dear users,

from August 5, 2019, on HLRN will open outgoing network connections world wide, however limited to destination ports for ssh, http, and https (22, 80, and 443). At the same time HLRN will remove the list of external target hosts, that a number of users have maintained, as this is not needed anymore.

Action is required for users, that need to connect to external servers in their workflow via non-standard ports. This includes

- users of commercially licensed software (Abaqus, Ansys, CFX, StarCCM+, etc.),

- users connecting to external ports other that the above mentioned.

Those users, and others, that experience connection problems in their workflow on HLRN after August 5, should immediately contact HLRN Support indicating the external host (hostname and ip address) and the port(s), that need to be reached from HLRN.
