PRACE Scientific Conference 2012 on June 17, 2012 @ ISC'12 in Hamburg
by LRZ aktuell April 25, 2012

April 25, 2012

The 2012 PRACE Scientific Conference will be held on Sunday, June 17, in Hamburg, Germany. Top European scientists will highlight advances in large scale simulation and key results obtained with support by PRACE, the Partnership for Advanced Computing in Europe. The European Commission and the PRACE director will present Europe s vision for HPC. Scientist and researchers from academia and industry are cordially invited to participate, learn from colleagues what can be achieved using PRACE services and indentify opportunities for future PRACE supported projects. The programme will include a short meeting of the User Forum which will provide an opportunity for users and those considering applying for PRACE resources to discuss issues with the PRACE management and members of the Scientific Steering Committee. This year PRACE partners with ISC, the International Supercomputing Conference, maximizing the value for PRACE and ISC 12 attendees. Participation in the PRACE programme on Sunday is free of charge. However, all participants should register via the ISC registration. After the end of the sessions PRACE and ISC invite you to an informal get-together with colleagues from Asia-Pacific participating in the Asia-Pacific day organised in parallel by ISC.

Linux-Cluster: Interruption of operation (reminder)
by LRZ aktuell April 25, 2012

April 25, 2012

Dear users of the Cluster systems at LRZ, as announced in http://www.lrz.de/aktuell/ali4261/ user operation on the cluster will be interrupted due to an electrical power shutdown test which affects all storage systems. In order to cleanly shut down all accesses to the storage systems, we have already started to drain the SLURM queues and all running jobs will be removed from 4:30 pm onwards. Please also note that after this interruption, the SGE queues mpi_8, shm_8, mpi_32 and shm_32 will become permanently unavailable because the systems will be upgraded and moved to SLURM. The SLURM documentation will be appropriately updated as soon as this upgrade is completed. We will keep you up-to-date about the status of the cluster via this document.

SuperMIG unavailable (reminder and update)
by LRZ aktuell April 25, 2012

April 25, 2012

Dear users of SuperMIG, the power cut-off tests announced in http://www.lrz.de/aktuell/ali4261/ will also cause an interruption of service for SuperMIG, since the NAS filesystems will not be available. Access to SuperMIG will not be possible from March 25th, 17:00 until March 26th, 18:00. The downtime will also be used to perform the regular sytem maintenance. We apologize for the inconvenience caused by this interrupt and will inform you through this ALI when the system is back in production.
