Traces from existing parallel and distributed computing systems are a useful resource for researchers to replicate real-life workloads for their experiments. However, since cloud computing is a relatively new area few such traces are currently available.

We have developed a trace data structure based on data from OpenStack Nova, as well as software (which will be published later) to extract the appropriate data. We are making available data from the OpenStack KVM cloud operated by the Chameleon testbed for educational projects.
