Safe at Any Speed: Fast, Safe Parallelism in Servers

Free registration required

Executive Summary

Many applications take advantage of parallelism to increase performance. Servers are a particularly common case as they must multiplex resources across many simultaneous users. Unfortunately, writing concurrent applications is difficult and prone to subtle and non-deterministic bugs that are difficult to reproduce. This paper advocate an approach to developing concurrent programs that is safe by default. Conservative static analysis determines when two code segments may safely run in parallel, and a runtime scheduler respects these constraints.
