Tape Restore Temporarily Unavailable

An ongoing issue with tape restores affecting Lustre stability has necessitated the temporary disabling of file restores from tape. Cray recognise this issue as critical and are putting a great deal of focus on to resolving the issue as soon as possible. If you are trying to access a file and receive the message:

Cannot send HSM request .... Resource temporarily unavailable

... please contact us at help@hpc.kaust.edu.sa, and we will endeavour to recover the file for you.

Shaheen Operating on Reduced Capacity

Due to maintenance on the UPS system to replace the batteries, Shaheen will be operating on sligthly reduced capacity from 13th Feb 2017 until 12th March 2017. Up to 515 nodes will be offline to reduce power load, this will mean that the maximum size job that can be run during this period is 5643 nodes.

HPC Training Tutorials

Two days of HPC training tutorials are organized on 15th and 16th March at KAUST:

  • Wednesday 15th March: HPCSAUDI Conference Tutorials with 8 different sessions. These half or full day tutorials are suitable for new, intermediate and advanced users, managers, students, systems administrators and anyone seeking an overview of parallel computing; debugging, performance and optimization tools; scientific applications; use of compute accelerators ( Xeon Phi, GPUs), systems administration and resource management; procuring HPC systems.
  • Thursday 16th March:  Workshop on Best Practices for Parallel I/O and Polyclinic. The morning session will cover the architecture, general parallel I/O models, file system tuning, I/O tracing, MPI-IO usage, and general best practices.The afternoon session will be dedicated to a code polyclinic where KSL CS team, Seagate, along with Intel and Cray application engineers will help users to tune and optimize their codes for compute, scalability and I/O.

Any questions on the Training, please contact us at training@hpc.kaust.edu.sa
