Next computer system in Kamioka from March 2022

CentOS7 has been used in Kamioka since 2017. Because the next computer system will be used till 2027, we need to select a new OS. As a natural consequence, Enterprise Linux 8 (RHEL8) or compatible one is selected. One of the major changes is the version of the compiler. It was 4.9.5 in CentOS7 but the one in RHEL8 is 8.3.1.
