Naos: Serialization-free RDMA networking in Java
summary
Naos implements a serialization-free Java networking layer that uses RDMA write to remote heap to copy on-heap objects verbatim, then runs a DFS-based pointer-fix pass using DFS pointer-fix metadata to repair invalid pointers and class references while protecting GC safety. It exposes a simple connection API over InfiniBand verbs, offloads CPU work, and reports microbenchmarks: ~8 µs latency for float arrays and an optimized synchronous mode reaching 1.5 billion requests/sec (after an initial 250k/sec blocking prototype).
