FUGU: Implementing Translation and Protection in a Multiuser, Multimodel Multiprocessor

Abstract

Multimodel multiprocessors provide both shared memory and message passing primitives to the user for efficient communication. In a multiuser machine, translation permits machine resource to be virtualized and protection permits users to be isolated. The challenge in a multiuser multiprocessor is to provide translation and protection sufficient for general-purpose computing without compromising communication performance, particularly the performance of communication between parallel threads belong to the same computation.
