Despite significant progress in recent years, the important problem of static race detection remains open. Previous techniques took a general approach and looked for races by analyzing the effects induced by low-level concurrency constructs (e.g., ...

Performance bugs are programming errors that slow down program execution. While existing techniques can detect various types of performance bugs, a crucial and practical aspect of performance bugs has not received the attention it deserves: how likely ...

In recent years, web applications have become pervasive. Their backbone is JavaScript, the only programming language supported by all major web browsers. Most browsers run on desktop or mobile devices with parallel hardware. However, JavaScript is by ...

Running compute-intensive or blocking I/O operations in the UI event thread of smartphone apps can severely degrade responsiveness. Despite the fact that Android supports writing concurrent code via AsyncTask, we know little about how developers use ...

We present an approach for automatic translation of sequential, imperative code into a parallel MapReduce framework. Automating such a translation is challenging: imperative updates must be translated into a functional MapReduce form in a manner that ...

In the multicore era, sequential programs need to be refactored for parallelism. The next version of Java provides ParallelArray, an array datastructure that supports parallel operations over the array elements. For example, one can apply a procedure to ...
