To all users of the Supercomputer Systems:

Since 10:15 p.m. on May 28, I/O waiting has been occurring for a long time in some directories in the mass storage (/LARGE1) when accessing files.
We are currently working on restoring the system, so if you are experiencing I/O wait, we would appreciate it if you could wait for a while.

We apologize for the inconvenience and appreciate your understanding and cooperation.
