Supercomputing Division, Information Technology Center, The University Tokyo

Trial Use Course (Free Trial)

 The Information Technology Center, The University of Tokyo (hereafter, "the Center") has launched a paying trial use course for corporations, universities and public organizations since FY2011. In response to requests of short period trial use such as trying their application, the Center launched Trial Use Course (Free Trial) since FY2019. Applicants can try out the supercomputer systems of the Center for free, although the resources of them are limited. In FY2019, it will be providing Reedbush, Oakforest-PACS and Oakbridge-CX services.

 The trial use course (free trial) allows users to try out the supercomputer systems and get a sense of using the supercomputers. They may then make the transition to general use course or trial use course (Academic, Corporations). The shift to these courses is expected to promote the further use of computer systems.
