HPC: bwUniCluster, ForHLR I and ForHLR II not available

On Saturday, 30 September 2017, there will be a power shutdown at SCC buildings, 20.20 and 20.21, of KIT Campus South, so that operation of the HPC systems will not be possible at this weekend. At the same time, repair work of the cooling-system infrastructure of the ForHLR building at Campus North and a maintenance of the cooling-system of ForHLR II are scheduled, so a shutdown of this system will be necessary as well.
On this occasion, we schedule an extensive (software-)maintenance for all clusters and file systems before the shutdown that is necessary anyway. These activities include updating filesystem-software, operation systems and other software components (OFED-stack of ForHLR II, etc.). The firmware of many hardware components has to be updated as well.

By combining all upcoming maintenance activities to one "large" maintenance, we avoid several short interruptions, so that the use of the clusters will be restricted for a shorter time overall (the clusters have to be cleared of running jobs only once, etc.).

For this reason, from

Tuesday, 26 September 2017 until Monday, 02 October 2017,

the clusters bwUniCluster, ForHLR I and ForHLR II as well as the corresponding file systems will be out of operation.

During this time, it is not possible to log in to the systems. Running jobs will be cancelled; the job-queue will be deleted only on ForHLR II. Data on the parallel file systems will remain intact.

As a precaution we want to point out that such an extensive maintenance and the power shutdown always involves imponderabilities. Especially, after a power shutdown hardware failures can not be ruled out. So it is possible that, because of the holiday (3.10.), the return to operation of some parts of the systems will be delayed until Wednesday, 04 October 2017.
