StarExec is a cross community logic solving service developed at the University of Iowa under the direction of principal investigators Aaron Stump (Iowa), Geoff Sutcliffe (University of Miami), and Cesare Tinelli (Iowa).

Its main goal is to facilitate the experimental evaluation of logic solvers, broadly understood as automated tools based on formal reasoning. The service is designed to provide a single piece of storage and computing infrastructure to logic solving communities and their members. It aims at reducing duplication of effort and resources as well as enabling individual researchers or groups with no access to comparable infrastructure.

StarExec allows

The first public events ran on StarExec in Summer 2013 (CoCo 2013 and SMT-EVAL 2013). Several more will run in Summer 2014.

See here for machine specifications for the compute nodes.

A virtual machine for StarExec is here. It is recommended to upgrade to the latest VirtualBox for this (confirmed working for version 4.3.24).

Use of StarExec is bound by the following terms of service.

Development details can be found on our public development wiki.
