A Vision to Compute like Nature: Thermodynamically
Advocating a new, physically grounded, computational paradigm centered on thermodynamics and an emerging understanding of using thermodynamics to solve problems.
Technical Perspective: Why ‘Correct’ Computers Can Leak Your Information
"Spectre Attacks: Exploiting Speculative Execution," by Paul Kocher, et al., reviews how speculative execution and caches can be exploited, presents specific exploits using speculative branches that are direct and indirect, and discusses software and hardware options for mitigating Spectre.
Why On-Chip Cache Coherence Is Here to Stay
On-chip hardware coherence can scale gracefully as the number of cores increases.
Two Hardware-Based Approaches For Deterministic Multiprocessor Replay
Modern computer systems are inherently nondeterministic due to a variety of events that occur during an execution. The lack of repeatability that arises from this nondeterminism can make it difficult to develop and maintain correct software.
A Wiki For Discussing and Promoting Best Practices in Research
Dealing with the demands of escalating paper submissions is a daunting challenge for conference organizers and program chairs. ACM and IEEE have joined forces to create a forum for sharing ideas on the best ways to handle it all.
Cache considerations for multiprocessor programmers
Although caches in most computers are invisible to programmers, they significantly affect program performance. This is particularly true for cache-coherent, shared-memory multiprocessors. This article presents recent research into the performance of parallel programs and its implications for programmers who may know little about caches.
