Dear HPC users,

Today denotes the official beginning of summer 2018.
Below are a few information we wanted to share with you at this occasion:

• Uni.lu HPC School 2018: the 8th edition, held in Belval on June 12-13, 2018 was a great success.

  • You can find program details on this page.
    • You might want to also review the main keynote slides.
  • As always, we have spent quite some time and effort to provide up-to-date contents and new materials.
    • If you've missed the tutorials, you might want to check out their content available on http://ulhpc-tutorials.readthedocs.io/.
    • Feel free to report your comments and feedback on the session contents and help us improve our next trainings.
    • The next HPC school is scheduled for November (exact date will be communicated in due time).

• Quota change on the gaia cluster

  • As you probably noticed, the storage usage on GPFS within the gaia cluster is too high (96%) and we cannot extend further its storage systems.
  • As a preventive measure, we had to 'freeze' the current soft quota limits and reset the hard limit to avoid file system crash.
    • you can use the df-ulhpc tool to check your current usage and limits
    • please check if you can clean up unneeded data or move it elsewhere
    • we are planning to move work directories ($WORK) to Lustre (previously only hosting $SCRATCH) to save some space on the main storage units, this process will be transparent to you
  • If possible, consider moving you project data to Isilon or (better) the flagship HPC cluster iris.

• 2018 Software set update

  • Updated software sets are about to be released in the coming weeks.
  • You can already try them using module use /opt/apps/resif/data/devel/default/modules/all/
  • A short maintenance of the iris cluster is also scheduled on Monday, July 2nd to allow for a few security updates -- see #876

• Incoming developments and deployments

  • We are about to release a new tender document (RFP 180027) to extend the iris cluster with GPU-enabled computing nodes, as well as bigmem nodes.
  • This should allow to exceed the 1 PFlops total computing capacity for the UL HPC facility.

Thanks for your understanding, we wish you a wonderful summer.
Happy Computing!

The UL HPC Team
