3 Nov 2021: This server is in production and should be used preferably from now on. We provide a default CPU queue for small jobs (typically for result submission competitions). For code submission, organizers are expected to provide their own queue, see instructions. As an incentive to start using this server, we provide a GPU queue, see application form.

11 Sep 2021: Welcome to the new Python3 version of Codalab. It includes a few novel features including: updates of all packages Django and others; possibility to set submission size quotas to keeping storage growth under control; and, a novel admin interface for organizers.
