The Nano Cluster currently has 54 compute nodes and 1 frontends with the following configurations:
Access to the Nano cluster is limited to affiliates of the 6 project PI's. To apply for an account, visit the Account Request Form.
The frontend node, nano.millennium.berkeley.edu, is accessible via SSHv2.
The nano-users mailing list is a forum for community support of the Nano cluster. All users are added to this list by default but have the option of unsubscribing.
To submit a script to Torque, run
qsub script.sh. Torque defines environment variables and runs your script on the first assigned node; it does not launch processes on multiple cpus. You may use
mpirun within your script to launch processes on multiple assigned nodes.
The default queue is “batch” which contains all nodes. View the output of
qstat -a or
qstat -qto check the queue status.
If you are unfamiliar with MPI, please visit the MPI_Tutorial. MPI jobs can be run over the gigabit Ethernet.
/home/nano/$group/$useris your home directory.
/home/nano/$group/workis group writable scratch space.
/home/nano/$group/softwareis group writeable for software installation.\
/home/nano/$group/software/binis in your PATH by default.
/usr/millcontains supported software, including MPI and IBM compilers.
/usr/mill/binis in your path by default.
/scratchis local world writable storage on each node and should be used instead of /tmp.
/scratchhas a 30 day auto-deletion policy; any file not used within 30 days will be deleted automatically.
Nothing is backed up, ever. Please plan accordingly.
