The Partnership for Advanced Computing in Europe (PRACE) and the Extreme Science and Engineering Discovery Environment (XSEDE) have collaborated to offer the third European-U.S. Summer School on HPC Challenges in Computational Sciences. Goals of the summer school are for attending graduate students and postdoctoral students to gain greater knowledge about high performance computing (HPC) and its applications in multiple fields of science and engineering and to foster new collegial friendships and partnerships among the international presenters and attendees. The expense-paid program will benefit scholars from European and U.S. institutions who currently use HPC to conduct research. The school will take place June 24-28, 2012 in Dublin, Ireland. Deadline to apply is Sunday, March 18, 2012.
