Cluster 2

This is the default lab cluster.

Priorities and Policies

• Lab Security Policy
• Disk space policy
• Backups policy.
• Portal system for off-site ssh cluster access.
• Get a Cluster 2 account and get started

Special machines

Normally, you will just ssh to sgehead aka gimel from portal.ucsf.bkslab.org where you can do almost anything, including job management. A few things require licensing and must be done on special machines.

• Sigma can definitely go off and stay off. It was planned for a fingerprinting server, never done.
• kappa is licensing. ask me.
• Rho is the wiki. stays on
• Psi is fortran and stays on
• Tau is the web server, and will move to he
• he also hosts:
• alpha - which is critical and runs foreman, DNS, and other important services
• beta - with runs LDAP and is important
• gamma -=

• psi for using the PG fortran compiler
• ppilot is at http://zeta:9944/ - you must be on the Cluster 2 private network to use it
• no other special machines

Notes

• to get from SVN, use svn ssh+svn

Hardware and physical location

• 1856 cpu-cores for queued jobs
• 128 cpu-cores for infrastructure, databases, management and ad hoc jobs.
• 788 TB of high quality NFS-available disk
• Our policy is to have 4 GB RAM per cpu-core unless otherwise specified.
• Machines older than 3 years may have 2GB/core and 6 years old have 1GB/core.
• Cluster 2 is currently stored entirely in Rack 0 which is in Row 0, Position 4 of BH101 at 1700 4th St (Byers Hall).
• Central services are on he,aleph2,and bet
• CPU
  • 3 Silicon Mechanics Rackform nServ A4412.v4 s, each comprising 4 computers of 32 cpu-cores for a total of 384 cpu-cores.
  • 1 Dell C6145 with 128 cores.
  • An HP DL165G7 (24-way) is sgehead
  • more computers to come from Cluster 0, when Cluster 2 is fully ready.
• DISK
  • HP disks - 40 TB RAID6 SAS (new in 2014)
  • Silicon Mechanics NAS - new in 2014 - 77 TB RAID6 SAS (new in 2014)
  • A HP DL160G5 and an MSA60 with 12 TB SAS (disks new in 2014)

= Naming convention

• The Hebrew alphabet is used for physical machines
• Greek letters for VMs.
• Functions (e.g. sgehead) are aliases (CNAMEs).
• compbio.ucsf.edu and ucsf.bkslab.org domains both supported.

Disk organization

• shin aka nas1 mounted as /nfs/db/ = 72 TB SAS RAID6
• bet aka happy, internal: /nfs/store and psql (temp) as 10 TB SATA RAID10
• elated on happy: /nfs/work only as 36 TB SAS RAID6
• dalet exports /nfs/home & /nfs/home2

Special purpose machines - all .ucsf.bkslab.org

• sgehead aka gimel.cluster - nearly the only machine you'll need.
• psi.cluster - PG fortran compiler (if it only has a .cluster address means it has no public address)
• portal aka epsilon - secure access
• zeta.cluster - Pipeline Pilot
• shin, bet, and dalet are the three NFS servers. You should not need to log in to them.

on teague desktop, /usr/local/RAID Web Console 2/startupui.sh 
connect to shin on public network
raid /  C2 on shin

• mysql1.cluster - general purpose mysql server (like former scratch)
• pg1.cluster - general purpose postgres server
• fprint.cluster - fingerprinting server
