Finding Concurrency Bugs Under Imprecise Harnesses

Finding Concurrency Bugs In Java

Because threads are a core feature of the Java language, the widespread adoption of Java has exposed a much wider audience to concurrency than previous languages have. Concurrent programs are notoriously difficult to write correctly, and many subtle bugs can result from incorrect use of threads and synchronization. Therefore, finding techniques to find concurrency bugs is an important problem. ...

Effective testing for concurrency bugs

In the current multi-core era, concurrency bugs are a serious threat to software reliability. As hardware becomes more parallel, concurrent programming will become increasingly pervasive. However, correct concurrent programming is known to be extremely challenging for developers and can easily lead to the introduction of concurrency bugs. This dissertation addresses this challenge by proposing ...

Detecting and Mitigating Concurrency Bugs

Suppressing Concurrency Bugs Using Scheduler Shepherding

Race conditions, atomicity violations, and related concurrency bugs are often due to inadequate synchronization that fail to prevent specific (undesirable) thread interleavings. Such errors, often referred to as Heisenbugs, are difficult to detect, prevent, and repair. In this paper, we present a new technique to increase program robustness against Heisenbugs. Our solution leverages correct pro...
