Abstract
The analysis techniques described are used in the implementation of a virtual machine that guarantees sequentially consistent execution of Java bytecodes. This implementation is used to show the effectiveness of our analysis algorithms. On many benchmark programs, the performance of programs on our system is close to 100% of the performance of the same programs executing under a relaxed memory model. Specifically, we observe an average slowdown of 10% on an Intel Xeon platform, with slowdowns of 7% or less for 7 out of 10 benchmarks. On an IBM Power3 platform, we observe an average slowdown of 26%, with slowdowns of 7% or less for 8 out of 10 benchmarks.
