HWNI Neuro Cluster Technical Specifications

Last modified:June 23, 2020

Location

The Neuro cluster is located in the UC Berkeley data center, a hardened facility that provides a precision environment for mission-critical servers and related equipment.

Compute nodes

There are over 28 workstations in the Neuro cluster available for remote desktop and batch processing.
Together, the workstations provide 500x3Ghz Intel CPU cores and over 4TB of DDR3 RAM.
The workstations also provide a total of 8 Graphics processors: Geforce Tesla V100, Tesla M2050, and Geforce GTX470 for graphics rendering.

Data Storage

  • Enterprise drives provide over a petabyte (PB) of usable disk space.
  • XFS 64-bit Journaling Filesystem is a stable, high-performance filesystem proficient at handling large files.
  • Network File System (NFS) Servers provide access to filesystems with multi-gigabit ethernet.
  • For increased availability, data backups are stored on a different file server (and filesystem) from the original data. For more information about data backups, see data backups.

Network Services

Network services include:

  • CUPS print service
  • Grid Engine batch processing service
  • Nagios monitoring service
  • LDAPS directory service
  • HTTPS web services
  • Secure login via 2-factor authentication ssh/sftp/sshfs

Network security

The network services listed above are deployed with virtual machines for increased redundancy, privacy and security. All login services use 2-factor authentication with SSH/SSL, restricted to pre-approved users with a strong password or SSH key. Repeated unsuccessful login attempts are logged and blocked. Workstations, NFS servers, and some virtual machines are only accessible from a private network address (RFC 1918) for increased privacy and security.

Software

The operating system is 64-bit CentOS linux.
Scientific Applications are located on all workstations
