Addressing the Challenges of Tera-scale Computing

Hardware and Software Approaches for Deterministic Multi-processor Replay of Concurrent Programs

Article Description

In this article, we explore hardware and software avenues for improving the programmability of Intel® multi-processors. In particular, we investigate techniques for reproducing a non-deterministic program execution that can efficiently deal with the issues just mentioned. We identify the main challenges associated with these techniques, examine opportunities to overcome some of these challenges, and explore potential usage models of program execution reproducibility for debugging and fault tolerance of concurrent programs.
