JAXA Supercomputer System Annual Report April 2018-March 2019

Resource allocation

Five useage classifications shown in Table 1 are set, and even if JSS2 is very crouded, use is guaranteed up to the allocation rate set for each usage classification.

When JSS2 is vacant, crowded classifications could use resources exceeding the allocation limt, and efforts are made to make effective use of resources.

The allocation results in Fig. 1 shows the result of the overall control by the job scheduler. Specified project use is increasing.

Fig.1 Trend of Usage classification and allocation (FY2016-2018)

Usage result of specified projects

In FY2017 and FY2018, four projects shown in Table 2 were selected as prioritized tasks.

Comparison of FY2017 and FY2018 in Fig.2 shows that the usage results occupying the whole of priority use are increasing, and the H3 project has increased 1.4 times for the four projects. In FY2019, new projects will be selected in light of the new business plan.

Usage result by field

Top application of aeronautical Technology is 45%, but there are many applications of space related fields and research and development. Contributing to external contributions such as contract research, facility sharing, JSS2 Inter-University Research, and student training (Skill Acquisition System).
