BioExcel is the leading European Centre of Excellence for Computational Biomolecular Research. Established in 2015, the centre has grown into a major research and innovation hub for scientific computing. BioExcel develops some of the most popular applications for modelling and simulations of biomolecular systems. A broad range of additional pre-/post-processing tools are integrated with the core applications within user-friendly workflows and container solutions. The software stack comes with great performance and scalability capabilities for extreme-scale utilization of the worlds largest high-performance computing (HPC) and high-throughput computing (HTC) compute resource. BioExcel has developed an extensive training program to address competence gaps in extreme-scale scientific computing for beginners, advanced users and HPC/HTC system maintainers
