AI_INFN Technical meeting – Minutes and actions

Date: 2025-01-13

Operations

We have restarted the minio cluster providing resources to JuiceFS and moved the metadata engine from Redis to PostgreSQL. No performance degradation was observed. Drafted dashboards for PostgreSQL and Minio.
On January 11, failures of cvmfs fuse mounts were reported. Problem identified and (hopefully) fixed: squid proxy was configured without defining the port (3128).

Tracked developments:

Automation of RKE2 deployments in INFN Cloud

The button in the INFN Cloud dashboard redirecting to the AI_INFN platform has been added.
For the moment it is only visible in the development-version of the PaaS and for users in the admin/ai-infn group.
Gioacchino pushed the docker images of the JupyterLab and of the JupyterHub in the repository of DataCloud with automated build.
- Observed strange old-version of snakemake in conda, in principle not installed from Docker image.
- Lucio will try to use Gioacchino’s image as default image in AI_INFN Platform.

Develop monitoring and accounting infrastructure (R. Petrini)

The grafana dashboard has been extended to:
- monitor the hackathon platform
- monitor the Postgres used for the new JuiceFS
- monitor the MinIO instance used by the new JuiceFS (this works only partially: 1/3 dashboards)
Improving the monitoring of postgres and minio requires some “invasive” action, at least for trial and error. It was decided to create a test environment with much more limited disk space but the same configuration as a playground for setting up the monitoring. This will also enable documenting the construction procedure of the storage cluster.

Environment setup (S. Giagu, S. Bordoni, L. Cappelli)

Luca Clissa reported a problem cloning an environment. Lucio is following up.

Offloading tests with virtual kubelets (G. Bianchini, D. Ciangottini)

Giulio (offline) - (almost) solved two issues raised by Lucio in interLink api server

Acquisto FPGA

The game is in Diego Michelotto’s ballpark: the most promising strategy is installing the Xilinx software in the bare metal and then re-insert the higher level in the virtualization.
Unfortunately Alma 9 is not officially supported by Xilinx. So, it’s hard to guarantee success.
Enrico Calore reports on a discussion he had with the engineers from Xilinx at the SuperComputing conference. VitisAI won’t be supported for new hardware boards and VHDL/HLS will provide the most important toolchain for the upcoming FPGAs. Unfortunately V70 FPGAs can only be programmed using VitisAI.
Andrea Rigoni supports the need for FPGAs in the Cloud, possibly close to GPU devices, for quantization studies: https://indico.cern.ch/event/1405026/contributions/5910214/attachments/2933286/5151597/cern_edge_ml_fpga_ai.pdf
