The network interfaces of existing multicomputers require a significant amount
of software overhead at the operating system and user levels to provide
protection and to implement message passing protocols. This paper describes
the design of a low-latency, high-bandwidth, virtual memory-mapped network
interface for the SHRIMP multicomputer project at Princeton University.
Without sacrificing protection, the network interface achieves low latency by
using virtual memory mapping and write-latency hiding techniques, and obtains
high bandwidth by providing a user-level block data transfer mechanism. We
have implemented several message passing primitives in an experimental
environment, demonstrating that our approach can reduce the message passing
overhead to a few user-level instructions.
