Abstract
Thread-Level Speculation has been used to take advantage
of multicore processors in virtual execution environments
for the sequential JavaScript scripting language. While the results
are promising the memory overhead is high. Here we propose to
reduce the memory usage by limiting the checkpoint depth based
on an in-depth study of the memory and execution time effects.
We also propose an adaptive heuristic to dynamically adjust the
checkpoints. We evaluate this using 15 web applications on an
8-core computer. The results show that the memory overhead is
reduced for Thread-Level Speculation by over 90% as compared
to storing all checkpoints. Further, the performance is often better
than when storing all the checkpoints and at worst 4% slower.
