What characteristic of edge networks does Cleave exploit?
Cleave exploits the asymmetry in edge network bandwidth, where downlink capacity significantly exceeds uplink (2-10x), aligning with the I/O pattern of GEMM operations.
😎
😊
How does Cleave achieve decreasing per-device communication as more devices join?
Cleave uses a parameter-server setup: input matrices are broadcast (downlink), each device returns a small partial output (uplink). Uplink data is distributed, so per-device communication drops as devices increase.
😎
🤓
How does Cleave's communication pattern fundamentally differ from traditional Tensor Parallelism (TP)?
TP keeps per-device traffic constant via frequent activation/gradient exchange. Cleave broadcasts (downlink) and gathers only partial results (uplink), so per-device traffic decreases as more devices join, unlike TP.
