Dr Kimihiko Hirao
Director of the RIKEN Advanced Institute for Computational Science: “Science in the 21st century needs to contribute to the sustainability of human society and produce technologies that support individuals. Supercomputing today is an invaluable foundation for advancing science and technology, and the scientific and technological achievements and knowledge gained through supercomputing will benefit humanity on many fronts. International collaboration is also increasingly
- important. This project follows this direction, and we aim to participate actively and
produce meaningful results.”

Professor Jack Dongarra
The University of Tennessee: “The OPL project is an important step in the right direction. Open software initiatives like this succeed at developing high-quality, standardised software and building new
- partnerships. Fujitsu’s initiatives should be recognised as a significant advancement
in the development process of petascale software and, more importantly, in collaborative communities to facilitate this development.”
