advance discipline

JAIST , one of Japan's premier academic research centers, will use the new
computer system to speed advances in the development of new algorithms for
massively parallel computers, large-scale simulations and visualization in
nanotechnology and biomechanics, and computational science.

As the global leader in HPC, Cray provides innovative supercomputing
systems that enable scientists and engineers in government, industry and
academia to meet both existing and future computational challenges.com for more
information. These include the technical
challenges of developing high performance computing systems, government
support and timing of supercomputer system purchases, the successful
porting of application programs to Cray computer systems, the successful
passing of acceptance tests, reliance on third-party suppliers, fluctuating
quarterly operating results, lower margins and earnings due to significant
pricing pressure, Cray's ability to keep up with rapid technological
change, Cray 's ability to compete against larger, more established
companies and innovative competitors, and general economic and market
conditions.

Computer science is the scientific discipline which aims to develop and advance knowledge related to computers and computation.

academic theoretical

Organized into three departments
(information science, materials science, and knowledge science), JAIST
provides up-to-date graduate training for up to 600 students while
maintaining competitive research programs through various dedicated
