CUDA course at GWDG, Göttingen, May 3rd, 2017
[3104] Apr 19, 2017

Graphic processors (GPUs) are increasingly used as computational accelerators for highly parallel applications. This course introduces hardware and parallelization concepts for GPUs and the CUDA programming environment for C and Fortran, including the language elements for controlling the processor parallelism and for accessing the various levels of memory.

Further information can be found in the course flyer (PDF).

Berlin: Maintenance on April 24+25, 2017
[3101] Apr 18, 2017

An extensive system maintenance has been scheduled on the Berlin complex Konrad

from Monday, April 24, 2017, 9:00,
until Tuesday, April 25, 2017, late afternoon.

All components of Konrad will be unavailable during this time. All login sessions will be terminated, and the batch system will be stopped.

During the maintenance most of the system components will receive software and firmware updates and upgrades to further improve stability and to fix a number of open issues.

We will post a message when user operation on Konrad has resumed.

Please plan accordingly.

Parallel Programming Workshop at ZIB, March 20-22, 2017
[3089] Mar 06, 2017

Current Intel Xeon Phi processors (Knights Landing - KNL) and next-generation Intel Xeon CPUs feature increasing core counts, integration of high-bandwidth memory (Xeon Phi), and wider SIMD units (AVX-512). Existing codes need to be modernized to take full advantage of the architectural features of these CPUs. Newly developed code should be designed to do so from the beginning.

We invite code developers to this 3-day workshop on advanced code optimization techniques on state-of-the-art and tomorrow`s multi- and many-core processors.

Agenda and Registration:

New Cray Development Toolkit CDT 16.12
[3077] Jan 13, 2017

The new Cray Development Toolkit CDT 16.12 is available for user test on both complexes Konrad and Gottfried.

CDT consists of Cray compilers, Cray Message Passing Toolkit (e.g. MPI), Cray performance tools (e.g. Perftools), libraries (e.g. LibSci, PETSc, Trilinos, FFTW), as well as the GNU Compiler Collection GCC, among others.

HLRN will switch all defaults in CDT from the current version to 16.12 on February 1, 2017 at 10:00.

Users that build and use their own code should test their build and execution chain with the new environment before February 1.

In order to do so call module load cdt/16.12 and rebuild your code.

Test the new executable in your batch job by loading the same module before the program call.
If your code uses dynamic shared libraries you need to add the line
export LD_LIBRARY_PATH=${CRAY_LD_LIBRARY_PATH}:${LD_LIBRARY_PATH}
before the call to aprun ....

In order to revert the shell environment to the current defaults, call module unload cdt/16.12 and follow the additional instructions.

Please notify HLRN Support if you experience any problems with the new development toolkit.

Wissenschaftsrat gibt grünes Licht für HLRN-IV
[3007] Jun 02, 2016

In seinen am 19.04.2016 veröffentlichten "Empfehlungen zur Förderung von Forschungsbauten (2017) (Drs. 5246-16)" hat der Wissenschaftsrat den Antrag zur Beschaffung des HLRN-Nachfolgerechners an den Standorten Berlin (ZIB) und Niedersachsen (Universität Göttingen) mit der bestmöglichen Note ausgezeichnet. In den Empfehlungen heißt es: "Die Kriterien für die Begutachtung von Forschungsbauten sind damit in höchstem Maße und sehr überzeugend erfüllt". (Lesen Sie mehr ...)

Enforcement of HLRN Email Policy
[3002] May 24, 2016

According to our published Email Policy HLRN requires all owners of an HLRN account to register together with it a valid email address from the institute, university or research organization they are affiliated with. This address identifies the user as a valid user of HLRN and must be used as sender address for all email to HLRN.

HLRN reserves the right to close an account immediately, when its registered email address becomes invalid (e.g. email is undeliverable).

In order to further improve security measures, HLRN will start now enforcing this policy by rejecting applications for new user accounts that have registered non-compliant email addresses, e.g. from email providers at (but not limited to) Google/gmail, Yahoo, Web.de, GMX, hotmail, and such. Contact HLRN user administration if you are unable to comply with the policy, but still require an HLRN account.

In a later phase HLRN will deal with existing user accounts that have non-compliant email addresses registered or users that use email addresses that differ from the registered one.

Thank you for your cooperation.
