Parallel Communication Obliviousness: One Round and Beyond
Summary: Analyzes communication-oblivious MPC algorithms, emphasizing one-round behavior and obliviousness-based compilation. Skew-free hashing incurs Omega(N) load under obliviousness, yet one-round natural joins reach best MPC loads; a compiler converts an l-round MPC with load L into a 2l-round oblivious version with (1+δ)L load.
