Simutrace is a tracing framework for full system simulators and has been conceived with full length, no-loss tracing of high-frequency events such as executed CPU instructions and main memory references in mind.

The framework places no restriction on the type and number of captured events and employs a scalable storage format, which easily handles traces of hundreds of gigabytes in size. Simutrace has been particularly extended to facilitate efficient memory tracing by incorporating aggressive, but fast memory trace compression.

Simutrace is a research project of the operating systems group at Karlsruhe Institute of Technology (KIT).
