Reasons and benefits of using JAXA Supercomputer System
Scientific data files are typically divided into units such as daily segments, making it easier to scale processing speed through simple parallelization.
Achievements of the Year
Higher-level processing was performed to release lunar seismic data acquired by the Apollo program in the 1960s-1970s. Although the dataset is only about 100GB in size, processing the proprietary binary format requires multiple stages of conversion when trying to utilize legacy software assets, which takes significant processing time on local computing environments. By using JSS, we were able to complete the processing within one day without expending human resources on software rewrites. Thanks to this, the data release could be carried out smoothly.
