Resource Information

Resource c3grid

ZAIK/RRZK provides non-BMBF-funded compute resources together with a BMBF-funded disk storage system to the C3Grid climate community (which is organized in the D-Grid VO C3Grid). Currently this system includes

  • SUN Opteron Cluster VZ20
    • up to 56 nodes for climate processing
    • 2 cores / node
    • 4-8 GB RAM / node
    • 1 node always reserved especially for VO C3Grid
    • Infiniband Interconnect
    • Grid access via Globus Toolkit 4.0.x through C3Grid portal
    • WS-Gram with SUN Grid Engine 6

  • Panasas AS-3000 Storage System
    • parallel file system PanFS
    • 10 TB capacity, shared with SuGI cluster, see below
    • within C3Grid used for workspace & data and compute providing issues

    • Infiniband Interconnect

  • Panasas AS-3000 Storage System
    • 5.0 TB for /scratch (all cluster nodes)
    • on agreement /home (all cluster nodes)

  • Globus 4.0.x Server
    • host:
    • GridFTP (access to /scratch & /home)
    • WS-Gram (with adapter for PBS/Torque)
    • RFT

Resource c3rc.zaik

The University of Cologne provides a BMBF-funded tape archive system which will together with equivalent components at AWI, DKRZ, DWD & ZIB build up a C3Grid community repository center (C3RC) for storing and retrieving large climate data bases of the C3 community. At the University of Cologne grid access is realized through SRM/dCache.

  • Storage Hardware
    • IBM Tapelibrary TS3500 mit 4 extension cabins
    • 4 x IBM TS1120 tape drives
    • 2 x IBM xSeries x3755 servers (TSM head node & dCache server)
    • 32 TB SATA

  • Grid Services
    • host:
    • dCache version: 1.9.0-2
    • protocols: srm, dcap, gsiftp, xrootd
