What is TSUBAME?

To advance science by computational modeling and simulations, a large-scale supercomputer TSUBAME* was deployed at GSIC in 2006, and has been providing computing and storage resources for research at Tokyo Tech. The machine has also been made available to select projects at outside research institutes and industries.

TSUBAME is also established to foster advanced education in computer and computational sciences, and is open to every student at the university, including undergraduates.

Second generation of TSUBAME, called TSUBAME2.0, was deployed in 2010, and upgraded to TSUBAME2.5 in 2013.

Third generation of TSUBAME, called TSUBAME3.0, was deployed in 2017, and operated in Mar, 2024.

Operation of TSUBAME 4.0 was started in Apr, 2024, and the latest information/status are found on TSUBAME4.0 Computing Services.
