MOAB is a cluster with 64 compute nodes based on Intel Harpertown processor and interconnected with Infiniband network. Has a peak performance of 3.6 TFlops. Nodes have 8 cores, 64 GB memory and 1 TB of local disk storage.

1. 1. Connecting to the system

• To access MOAB cluster, a SSH client (Secure Shell) must be used.
• For security reasons, access to our computing servers is restricted to Israeli university researchers only.
• Remote access will be set per PRACE application approval.
• Accessible through SSH protocol at hostname moab.iucc.ac.il. moab.iucc.ac.il is a prep area, where users may edit, compile, perform file management, and submit batch jobs.
