Abstract:
Execution of a program almost always involves multiple address
spaces, possibly across separate machines. Here, an approach to
reducing such costs using compiler optimization
techniques is presented. This paper elaborates
on the overall vision, and as a concrete example, describes
how this compiler assisted approach can be applied to the
optimization of system call performance on a single host.
Preliminary results suggest that this approach has the
potential to improve performance significantly depending
on the program's system call behavior.
