justIN Job Factory
The justIN Job Factory agent creates and submits wrapper jobs to HTCondor, which are each assigned to a specific execution site. It uses a mixture of matching successes, the outcome of test matches against the justIN database, and site limits set in the database to determine how many wrapper jobs to submit and have waiting at each site.
Once a wrapper job lands on a worker node, it contacts the allocator service which determines which unallocated files from one stage best match that worker node.
