This presentation was about 40% product review, 20% Lustre overview, and 40% technical tutorial overview. There were no new announcements.
Points of interest:
- About 65% of the lines of code in Lustre are provided by Intel.
- Lustre is used HPC organizations: Manufacturing and Finance stand out.
- Intel provides three versions of Lustre:
- Foundation – the open source base version
- Enterprise – the production version
- Cloud – available on AWS and Azure, allows users to replicate in-house data structures in the cloud.
- Enterprise Lustre:
- Works with Omni-Path “out of the box.”
- Security features supported include Kerberis and SELinux
- OpenZFS snapshot for check pointing
- Hadoop adaptor available
- Tip for using Omni-Path: CPU locality is important. This revelation seems to repeat itself with different technologies on a regular basis. I suspect that it is an ongoing conflict between marketing and technical support: The former is tasked with getting people interested in a product and tends to say all problems are now solved, while the latter is tasked with getting the product to actually work.
- In use on the Kraken system at the University of Tennessee.
- Basic message was that Omni-Path supports Lustre and “works out of the box.”
- This was mainly a technical seminar so no new announcements were made.
- Most of the audience questions dealt with product availability, compatibility, and interoperability.
- Intel used Mellanox as a synonym for InfiniBand perhaps in an effort to cast the open standard as a single vendor product.
