HMTT: A hybrid hardware/software tracing system for bridging the DRAM access trace's semantic gap |
Abstract | ||
|---|---|---|
DRAM access traces (i.e., off-chip memory references) can be extremely valuable for the design of memory subsystems and performance tuning of software. Hardware snooping on the off-chip memory interface is an effective and nonintrusive approach to monitoring and collecting real-life DRAM accesses. However, compared with software-based approaches, hardware snooping approaches typically lack semantic information, such as process/function/object identifiers, virtual addresses, and lock contexts, that is essential to the complete understanding of the systems and software under investigation. In this article, we propose a hybrid hardware/software mechanism that is able to collect off-chip memory reference traces with semantic information. We have designed and implemented a prototype system called HMTT (Hybrid Memory Trace Tool), which uses a custom-made DIMM connector to collect off-chip memory references and a high-level event-encoding scheme to correlate semantic information with memory references. In addition to providing complete, undistorted DRAM access traces, the proposed system is also able to perform various types of low-overhead profiling, such as object-relative accesses and multithread lock accesses. |
