E-CAM organizes application-specific ESDWs, focused on co-designing and development of software applications which include components that relate to HPC and extreme computing. Application-focused ESDWs will be typically one-week long events organized together with the application developers. E-CAM also organizes additional complementary ESDWs of interest to all four scientific areas of E-CAM (Classical MD, Electronic Structure, Quantum Dynamics, Meso and Multi-scale modelling) focused on teaching best practices and application development for next generation machines. Potential training topics for transversal ESDWs include, among others, software best practices, scalable computing frameworks, modern language standards, scalable IO and performance analysis. Targeted also to a broad scientific user base to embed coding best practices, extreme computing exploitation, and hardware awareness.
