Introduction » Memory Usage Tracker

Track memory usage.

The memory usage component vt::util::memory::MemoryUsage, accessed via vt::theMemUsage() is an optional VT component that tracks memory usage over time. It can be used with the Tracing component to write memory usage to Projections log files to track usage after each registered function executes. It can be configured to report usage after each LB phase is reached. This component is backed by a wide range of different reporters—everything from trapping memory allocation calls to counting allocated pages.
