Performance analysis on the gem5 simulation platform for researchers
To support the gem5 project, we've made the full version of Streamline available to project members. Get in-depth visibility into software execution and PMU on gem5 system models. Install Arm DS-5 Community Edition to get started with Streamline.
What is Streamline?
How does it benefit gem5 users?
Included in DS-5, Streamline presents a graphical view of system execution.
Streamline gives gem5 users a way of visualizing Linux and Android process information, along with charts which are built using counters.
Typically, Streamline is used for performance optimization, allowing you to spot problems such as excessive cache accesses and other issues which impact the performance of Arm-based systems. This general "dashboard" of system performance can be very useful throughout your experimentation or software development process, especially when used regularly.
