WP3 proposes explicit means to foster mutualisation of software development and computing/networking resources allowing for implementation of the roadmap defined in WP2. It is responsible for collecting analysis data from joint EU-US experimentation. It contributes specifically to the Coordinated deployment of software tools, networking infrastructures and testing sites allowing for mutualisation of resources between EU-USA platforms and communities. In particular it works closely with those emanating from European (ICT 17/19/20) and NSF (PAWR) collaborative project initiatives. WP3 will also assist partner projects in coordinating proof-of-concept joint demonstrations at high-profile venues bringing together teams from EU and USA platforms.
