Digital User Group Jan 2022 (Day 2 – Jan 19th)

19th January 2022 @ 15:00 - 17:00 GMT



Restarting for 2022, the SSUG::Digital talks are back with talks over two days.

Day 2 Talk 1: GPU Direct Storage with Spectrum Scale

With GPUDirect Storage (GDS) Nvidia has created a data path from the storage directly into the buffer of Nvidia GPUs. IBM Spectrum Scale is perfectly suited to take advantage of this feature from Nvidia to further enhance storage performance. This joint session by Nvidia and IBM development provides GDS overview, highlights how GDS has been integrated with Spectrum Scale and how it can be used to drive higher performance.

Day 2 Talk 2: Spectrum Scale performance improvements

Spectrum Scale is a highly scalable, high-performance storage solution for file and object storage. IBM continues to enhance Spectrum Scale performance, in response to recent hardware advancements and evolving workloads.  This presentation will discuss performance related improvements in  Spectrum Scale 5.X versions focusing on enhancements made in support of AI and HPC use cases, including improvements for IO 500 performance benchmark, improvements to RDMA to select NUMA aware adapters and more.

See >>here<< for sessions of Day 1 – Jan 18th, 2022.
