The memory allocator plays a key role in the performance of applications, but none of the existing profilers can pinpoint performance slowdowns caused by a memory allocator. Consequently, programmers may spend time improving application code ...

Diagnosing software failures is important but notoriously challenging. Existing work either requires extensive manual effort, imposing a serious privacy concern (for in-production systems), or cannot report sufficient information for bug fixes. This ...

Aquatic virtual reality (VR) is a minimally researched area. VR replaces what a user interacts with and sees with virtual objects and aquatic VR does the same while the user is in an aquatic environment (e.g., a pool) physically. As VR technology ...

Buffer overflow is possibly the most well-known memory issue. It can cause erratic program behavior, such as incorrect outputs and crashes, and can be exploited to issue security attacks. Detecting buffer overflows has drawn significant research ...

Deployed software is still faced with numerous in-production memory errors. They can significantly affect system reliability and security, causing application crashes, erratic execution behavior, or security attacks. Unfortunately, existing tools cannot ...

Due to the on-going threats posed by heap vulnerabilities, we design a novel secure allocator -- GUARDER--to defeat these vulnerabilities. GUARDER is different from existing secure allocators in the following aspects. Existing allocators either have low/...

Reproducing executions of multithreaded programs is very challenging due to many intrinsic and external non-deterministic factors. Existing RnR systems achieve significant progress in terms of performance overhead, but none targets the in-situ setting, ...

This paper presents the design and evaluation of a novel project designed to facilitate the learning of memory management concepts and interactions between different components. This project removes the complexity of a full or specific operating system ...

Deadlocks are critical problems afflicting parallel applications, causing software to hang with no further progress. Existing detection tools suffer not only from significant recording performance overhead, but also from excessive memory and/or storage ...

In spite of years of improvements to software security, heap-related attacks still remain a severe threat. One reason is that many existing memory allocators fall short in a variety of aspects. For instance, performance-oriented allocators are designed ...
