QFlex is a full-system simulation framework, simulating hundreds of cores. With this release, QFlex becomes the first full-system simulator to offer first-class support for statistical sampling and reusable checkpoints, enabling near-GIPS simulation speed. Statistical sampling cuts the time spent in cycle-accurate simulation by three orders of magnitude, while functional simulation fast-forwards through the rest of the execution and statistically guaranteed confidence levels ensure accuracy. The new version is available as a ready-to-use Docker image, along with new documentation to help you get started. QFlex is under active development, and we welcome your feedback and contributions on GitHub.
