This page is about how to use OCTOPUS. The system information on OCTOPUS is detailed from here.
Due to a BIOS malfunction, there is currently a limitation on available memory usage.
OCTOPUS has 768 GB of physical memory per node, of which up to 760 GB is typically available for user jobs. However, it is currently limited to a maximum of 742 GB for jobs due to a bug in the BIOS. Please note that if a job uses more than 742 GB, it will be terminated.
