We have identified there are some issues on OCTOPUS system.
Please check the following explanations:
 

- Memory usage limit due to BIOS issue
OCTOPUS has 768 GB of memory per node, of which up to 760 GB is typically available for computational jobs.
However, currently it is limited to a maximum of 742 GB for computational jobs.
Please note that if you use more than 742 GB, the job will be terminated.
 

- Degraded communication performance due to network switch failure
A failure has occurred in the network switch that connects nodes.
Jobs can still be executed.
However, delays may occur in communication between nodes.
 

- SQUID cannot access file system on OCTOPUS
The file system of OCTOPUS is designed to be accessible from the front-end server of SQUID via the path below.
　　/octfs/home
　　/octfs/work
However, currently these are not connectable.
The file system of SQUID is accessible from the front-end server of OCTOPUS.
If you copy data, please use from OCTOPUS.
 
 

We are currently working towards restoring service. We will provide further updates as soon as there is progress.
We apologize for any inconvenience this may cause, and we appreciate your understanding and cooperation.
