The International HPC Summer School on Challenges in Computational Sciences (IHPCSS) began in 2010 and is held annually, originally launched by NSF’s TeraGrid and the EU’s DEISA project. Over the years, the program has expanded to include participants from Japan, Canada, and more recently, Australia. A limited number of seats are also sponsored by organizations in the UK and South Africa. The school selects around 80 graduate students and post-docs each year, representing diverse scientific disciplines and over 20 nationalities. The program aims to immerse top students in cutting-edge HPC, foster networking, provide expert mentoring, and promote international collaboration and career opportunities. More details regarding IHPCSS are available here. The timeline of locations where IHPCSS has taken place from 2010 to 2024 is illustrated in the graph below.
