Agenda:

1. Announcements
2. Current status of the JRM
   1. Running JRM as a SLURM/SWIF Job
   2. SSH tunnel from the processing node (JRM) to the JIRIAF server, running Kubernetes API server.
   3. "Hello World" workflow within the JRM.
3. JIRIAF Available Resources DB Table (JAR)
   1. Suggested schema:
      1. computing_suite (e.g., HPC, GPU, etc.)
      2. resource_ID (unique identifier for each resource)
      3. resource_type (e.g., CPU, GPU, memory, etc.)
      4. number_of_cores
      5. memory
      6. available_walltime (decreasing over time)
         1. Available wall time will decrease over time.
         2. The wall time decrease below a certain threshold will trigger resource release.
         3. The wall time for the opportunistic resource (e.g., commercial cloud resource) will be clearly indicated in the table.
4. JIRIAF User Resource Requests DB Table (JURR)
   1. Suggested schema:
      1. name (user or group)
      2. resource_type (e.g., CPU, GPU, memory, etc.)
      3. number_of_cores
      4. memory
      5. wall time
      6. workflow_container_info (e.g., container ID, Docker image, etc.)
      7. data_type (streaming or batch files)
      8. can_it_be_horizontally_distributed/scaled (yes/no)
   2. Important question: Who is responsible for data provisioning, JIRIAF, or user workflow management system?
5. JIRIAF Workflow Resource Matching Service (JMS)
   1. Choice of technology/language: Python?
   2. The algorithm must be able to fit multiple user requests into a bigger resource (workflow Tetris).
6. Running CLAS12 Data-Stream Processing Pipeline
   1. Docker image for the CLAS12 data-stream processing pipeline.
7. Status of the Front-End
   1. JIRIAF Entry Web Page
   2. Connection to MariaDB Back-End
   3. JIRIAF REST API
