Revision as of 14:41, 23 April 2014
Our new cluster at UCSF is described on this page. The physical equipment in Cluster 0 will be subsumed into this cluster when Cluster 2 replicates all the functions of Cluster 0. We expect this to happen later in 2014.
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
Equipment
- 512 cpu-cores for queued jobs and 128 cpu-cores for infrastructure, databases, management and ad hoc jobs. 128 TB of high quality disk, 32 TB of other disk
- We expect this to grow to over 1200 cpu-cores and 200 TB in 2014 once Cluster 0 is merged with Cluster 2
- Our policy is to have 4 GB RAM per cpu-core unless otherwise specified.
- The Hebrew alphabet is used for physical machines, Greek for VMs. Functions (e.g. sgehead) are aliases (CNAMEs).
- Cluster 2 is currently stored entirely in Rack 0 which is in Row 0, Position 4 of BH101 at 1700 4th St (Byers Hall). More racks will be added by July.
- Central services are on aleph, an HP DL160G5 and bet, an HP xxxx.
- 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
- DISK
- HP disks - new in 2014 - 40 TB RAID6 SAS
- Silicon Mechanics NAS - new in 2014 - 76 TB RAID6 SAS
- A HP DL160G5 and an MSA60 with 12 TB SAS - new in 2014.
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
- het (43) aka former vmware2 MSA 60 exports /nfs/home and /nfs/soft
Special purpose machines - all .ucsf.bkslab.org
- sgehead- we recommend you use this - in addition to your desktop - for most purposes, including launching jobs on the cluster.
- pgf - fortran compiler
- portal - secure access from
- ppilot - pipeline pilot
- shin, bet, and dalet are the three NFS servers. You should not need to log in.
- mysql1 - general purpose mysql server (like former scratch)
- pg1 - general purpose postgres server
- fprint - fingerprinting server
