[ system problem ]

In response to the emergency declaration over COVID-19, all staff and engineers who operate and maintain the supercomputing system work from home.
On the Large-scale parallel computing server, the following problem occurred today.
4/22 8:00: the temperature in the cabinet increased
4/22 11:50-12:20: 43 calculation nodes went down
Therefore, we stopped 117 calculation nodes including down 43 nodes to prevent the spread of the problem at 20:35.
In response to the emergency declaration over COVID-19, people from outside Miyagi prefecture are not permitted to come to our center in order to prevent the spread of COVID-19 infection. Then, we cannot repair them now and it is not able to predict when these nodes will be repaired.
We will let you know after these nodes work. We will announce information related to this problem on our web site.
We apologize for your inconvenience and thank you for your understanding.
