DescriptionThe Operations and Computer Technologies Division at the RIKEN R-CCS is responsible for the operations of the entire K computer facility, which includes the auxiliary subsystems such as the power supply and water/air cooling systems. It is worth noting that part of these subsystems will be reused in the next supercomputer (Fugaku), thus a better understanding of the operational behavior as well as the potential impacts especially on the hardware failure and energy consumption would be greatly beneficial. In this poster, we will present some preliminary impressions of the impact of the water/air cooling system on the K computer system, focusing on the potential benefits of the use of low water/air temperature respectively for the CPU and DRAM memory modules produced by the cooling system. We expect that the obtained knowledge will be helpful for the decision support and/or operation planning of the next supercomputer.
