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. The centre maintains an extensive and growing network of industrial researchers in the pharmaceutical, chemical and food industries, and offers tailored products and consultancy services, while code development is done in close collaborations with hardware and software vendors to ensure compatibility and support for cutting-edge features. BioExcel works closely with various governmental, non-profit, educational and policy projects and initiatives.
