General characteristics
- Users need to get an account first (see W. Alef or H. Rottmann).
- Users should log into frontend.
- /home on the cluster is where the home directories reside. /home is visible to all nodes.
- login to nodes works from frontend without password
- All nodes have 16 GB of memory
- Each node has a scratch disk (~100 GB)
- for large amounts of disk space a 20 TB Raid is available (mounted under /data). If you need space, a directory can be created for you.
- Software available:
- gcc 4.2.1 (g++, gfortran)
- gcc 3.3.5 (g++, gfortran; under /cluster/gcc/3.3.5/bin/)
- OpenMPI, MPICH (OpenMPI automatically uses Infiniband)
- Intel Performance LIbrary
- a Batch system with load balancing could be turned on if need arises.
Cluster Booking
Please contact the VLBI correlator operators (Tel. 220, email: mk4) if you would like to allocate time on the cluster.
Check here to see when you can use which nodes and what diskspace on the cluster.
Defective nodes: node07 gives higher errors on IB. Will be invesigated
Available nodes: 1 - 60
Diskspace: ~200 GB on /home; more diskpace on request
Time period | Nodes assigned | Who | What | Diskspace | Comment |
