Threaded Software Dynamic Translation Master’s Project

Software dynamic translation and multiprocessing hardware are both becoming prevalent in today’s computing environment. Unfortunately, many of the programs being run under software dynamic translation are single threaded, and are unable to take advantage of thread level parallelism. This work presents the groundwork for enabling the Strata software dynamic translation framework to run in multiple threads. This allows the system to offload the work of translation into its own thread. Threaded Strata was tested by allowing the builder to speculatively build fragments that were not yet needed by the application. Using this technique threaded Strata able to speculatively build on average 69% of the fragments of the SPEC2000 CINT benchmark suite. Performance on these benchmarks gives us reason to believe that threaded software dynamic translation can be effective method of offloading work of the software dynamic translator.
