Due to the importance of reliability and security, prior works have proposed inlining meta-functions into applications for detecting bugs and security vulnerabilities. Such software techniques often add frequent, fine-grained instrumentation to programs and incur large runtime overheads. One way to reduce the cost is through parallelism. However, current architectures and compilers are not well suited to this task. At the architectural level, we found that current multicores do not efficiently support fine-grained and frequent communication between cores. We propose a hardware-accelerated queue (HAQu). HAQu adds hardware to a CMP that accelerates operations on software queues in an application¿s address space with operations that are compatible with a fully software queue. In the compiler, we studied a parallelization strategy that automatically extracts meta-functions from the main application and schedules their work load among many threads.
