Runahead Threads to improve SMT performance
In this paper, we propose Runahead Threads (RaT) as a valuable solution for both reducing resource contention and exploiting memory-level parallelism in Simultaneous Multithreaded...

Understanding Scheduling Replay Schemes
Modern microprocessors adopt speculative scheduling techniques where instructions are scheduled several clock cycles before they actually execute. Due to this scheduling delay, sc...

Structure-driven optimizations for amorphous data-parallel programs
Irregular algorithms are organized around pointer-based data structures such as graphs and trees, and they are ubiquitous in applications. Recent work by the Galois project has pr...

Tasking with out-of-order spawn in TLS chip multiprocessors: microarchitecture and compilation
Chip Multiprocessors (CMPs) are flexible, high-frequency platforms on which to support Thread-Level Speculation (TLS). However, for TLS to deliver on its promise, CMPs must explo...
