Quick recap

The meeting covered discussions on potential use cases for planes, performance optimization projects, and updates on various ongoing projects and events. The team explored challenges in supporting new features, standardizing APIs, and improving documentation. They also reviewed upcoming conferences and events, including the System Ready event and CC Summit, and debated the classification of new edge devices like the Nvidia GDX machine.

Next steps

• Jon and Jonathan to send emails to connect@linaro.org and copy Grant regarding concerns about the Friday schedule for confidential computing sessions at Linaro Connect.

• Leonardo to update the events information with the System Ready event details provided by Jon.

• Jon to organize a potential evening social event during the Confidential Computing Summit to bring together attendees from both that event and the System Ready event.

• Leonardo to set up a specific meeting to discuss shared virtual memory and other technical aspects of new super edge devices like the Nvidia Grace Hopper machines, after Connect.

• Attendees to come prepared with thoughts on gaps and discussion points regarding super edge devices for the Connect meeting.

Summary

Discussing Plane Use Cases and Performance

The meeting focused on discussing potential use cases for planes beyond the TPM one, with live migration being a good example. Leonardo mentioned that adding planes would not require changes to the operating system itself, mainly managed by the VMM and management layers. The team also discussed the challenges of supporting these features in the kernel and user space. Leonardo updated the team on the performance optimization project, mentioning that they plan to hire one candidate (Leonardo asking for approval for a second one) and build an internal performance optimization capability. The team also discussed the need for a standardized API for containers.

Performance Optimization Project Discussion

Jon and Leonardo discussed the performance optimization project, with Leonardo agreeing to send out a list of projects from last year. They also discussed the need for more documentation on http://developer.arm.com and the possibility of creating a white paper on certain algorithms. Leonardo mentioned that he would add the link to the backlog in the meeting minutes. They also discussed the closure of the SRCPC project, with Leonardo expressing sadness but not seeing any other way forward.

System Ready Event and Project Updates

Jon announced that the System Ready event will take place in June, likely on the 17th and 18th in Mountain View. Leonardo reported on the progress of two projects, Big Data & Data Science (BDDS) and Storage (STOR). The BDDS project is facing delays on the Bigtop Manager due to issues with the front-end interface, with the 1.0 release now expected in mid to late next month. The team is working on fixing build issues and buffer overflow on Arm64. The next steps for this project include releasing Big Top Manager and enabling the Arm64 CI in the Gluten community. For the Storage project, the team has been investigating various aspects and has enabled JuiceFS to run on Arm64. The next steps for this project include analyzing and fixing performance issues.

Updates on Upcoming Tech Conferences

Leonardo provided updates on various events, including the Open Confidential Computing Conference (OC3) in Berlin, Kubecon Europe, and the Linaro Connect in Lisbon. He mentioned that there will be an Endorsement API Hackathon before the Connect starts. Leonardo also discussed the crowded Friday morning schedule, which he plans to discuss with the marketing and events team. Randy and Jon suggested sending feedback to the Events team and copying Grant, who oversees the overall agenda for Connect.

CC Summit and System Ready Date

Leonardo discussed the upcoming CC Summit in San Francisco, noting an increase in talks related to remote attestation. Jon suggested organizing a happy hour for system ready attendees to coincide with the summit. Randy proposed shifting the system ready date to align with the summit, but Jon explained the challenges due to a holiday and travel considerations. Leonardo also mentioned the OCP Global Summit, Linux Plumbers in December, and the KVM Forum in Milan in September.

Nvidia GDX Device Management Discussion

Leonardo, Jon, and Kangkang discussed the new type of super edge device, specifically the Nvidia GDX type of machine. They debated whether it should be managed by the data center or edge group, with Leonardo suggesting it should be under the data center due to its similarity to servers. Jon agreed, adding that this device could be a great opportunity for the data center group to explore new directions, such as optimizing AI workloads. They also discussed the potential for this device to run various operating systems, including Windows. The team agreed to further discuss this topic at a future meeting, possibly at Connect.
