The Training Work Package (WP4) of the PRACE Fourth Implementation Phase (PRACE-4IP) project has continued the PRACE training programme by offering large variety of face-to-face training events as well as by developing on-line training services. During Feb 2015 – Apr 2017 PRACE-4IP has delivered 569 training days as part of 198 training events that have reached an audience of 4,492 participants. The training team has also started the conception of PRACE Training Centres (PTCs) for complementing the PRACE Advanced Training Centres (PATCs). Six Seasonal Schools have been organised within PRACE-4IP, and in collaboration with international partners the series of International HPC Summer Schools has continued to prosper. In order to better serve research communities such as the Centres of Excellence (CoEs), a new type of On-Demand training event has been introduced, and five such events have been organized. As a completely new training activity, PRACE has developed two Massively Open Online Courses (MOOCs). By mid-April 2017, 5,907 participants have enrolled in the two MOOCs. As a new online training activity PRACE has also piloted CodeVault, an open repository of high performance computing code samples. Overall, PRACE-4IP WP4 has delivered a vital service to foster the growth of computational skills in Europe and to strengthen the competitiveness of European science and industry in the field.
