The mantle convection workshop was held in Boulder, Colorado from June 19 to 23. About 26 graduate students and 39 geodynamicists and computational scientists attended the workshop. The morning sessions consisted of review and research talks, while afternoon sessions were for tutorials, demos, and practices. We also discussed community software needs and goals that may require help from the CIG. In this report to the CIG, we summarize the main outcome of these discussions
