About Us

UCCL (Ultra | Ultimate | Unified Communication Collective Library) is the next-generation AI/ML networking initiative at UC Berkeley’s Sky Computing Lab. We envision the next-generation AI/ML networking to have efficient CCL architectures, software-defined ML transport, and inter-vendor operability.
