Discussion¶
- Container backfill: GRACC can handle the new 'Execution Endpoint' service.
- GlideinWMS 3.9.1 is out; HTTP service has been split out of the default RPM to make containerization easier.
- Q (Marian): How does the factory know how much disk space is available for a slot?
- A (Marco): Uses what HTCondor reports (which is dynamically measured). Open HTCondor ticket (HTCONDOR-174) for adding a way to set a disk quota for a slot.
- HTCondor 8.9.12 will not be ready for 3.6 so we will ship 8.9.11.
