The Effects of Parameter Tuning in Software Thread-Level Speculation in JavaScript Engines

Martinsen, Jan Kasper; Grahn, Håkan and Isberg, Anders (2015) In ACM Transactions on Architecture and Code Optimization 11(4).
Abstract
JavaScript is a sequential programming language that has a large potential for parallel execution in Web applications. Thread-level speculation can take advantage of this, but it has a large memory overhead. In this article, we evaluate the effects of adjusting various parameters for thread-level speculation. Our results clearly show that thread-level speculation is a useful technique for taking advantage of multicore architectures for JavaScript in Web applications, that nested speculation is required in thread-level speculation, and that the execution characteristics of Web applications significantly reduce the needed memory, the number of threads, and the depth of our speculation.
