ATPESC provides doctoral students, postdocs, and computational scientists intensive hands-on training on the key skills, approaches and tools to design, implement, and execute computational science and engineering applications on current supercomputers and the HPC systems of the future. As a bridge to that future, this two-week program fills many gaps that exist in the training computational scientists typically receive through formal education or shorter courses. There are no fees to participate. Domestic airfare, meals, and lodging are provided.
