ECMWF is organising a Young Scientist Summer School (YSSS) in August 2017. The YSSS will introduce the young generation of researchers in numerical weather prediction, ocean, climate relevant topics as well as modern computational physics & energy efficient computing. During the school, the participants will get familiar with ESCAPE dwarfs – fundamental algorithmic building block – and recognize why HPC and energy‐efficient computations are important. The programme will include theoretical lecture material as well as practical exercises (to be realized by students as small‐scale research projects started from the 1st day of the school with defence of project results) on selected dwarfs.
