Crafty is a library for transactional storage, built for new non-volatile memory hardware. Taking advantage of hardware transactional capabilities of modern CPUs, it provides a low-overhead option that also eliminates the need for additional concurrency control.

This paper presents 2 data race detection analyses which analyze a single run of a program to predict data races that can happen in other runs. These analyses take advantage of data and control flow dependence to accurately understand how the analyzed program works, expanding what races can be predicted.

Predictive data race detection methods greatly improve the number of data races found, but they typically significantly slow down programs compared to their non-predictive counterparts. SmartTrack, through improved analyses and clever algorithms, reduces their overhead to just around non-predictive analyses without impacting their performance.
Predictive data race detection methods typically walk a tight line between predicting more races and avoiding false races. This paper presents a new analysis that can predict more races, and a method to efficiently eliminate false races.
