Outline of Final Research Achievements |
In this research, we developed a storage system called "PEANUTS", which utilizes persistent memory for supercomputers supporting high-performance computing. PEANUTS primarily aims to enhance the parallel read and write operations of single shared files, crucial in data science, addressing performance issues in large-scale environments that conventional storage systems struggled to resolve. By efficiently combining high-speed communication devices with persistent memory, these challenges were overcome, and data transfer speeds were significantly improved. This advancement suggests the potential for the use of large single shared files to become a standard I/O framework in data science.
