Computing in the Department of Statistics at UConn.
- The Department website has additional information about the cluster and computing resources in the department.
- Wenjie Wang has made some examples for the cluster.
- Henry Linder has made some useful default documents, including Rmarkdown templates and a boilerplate conference website.
cluster/ contains resources related to the
Statistics Department's Beowulf compute cluster. The cluster is
maintained by the Physics Department at UConn.
Purchase of the cluster and related software was partially supported by NSF Scientific Computing Research Environments for the Mathematical Sciences (SCREMS) Program grant 0723557 to M.H. Chen, Z. Chi (PI), D. Dey and O. Harel.

- HTCondor distributed computing scheduling software used on the cluster
cluster/example/ contains a fully-functional
example compute job.
notes.pdf contains notes and resources about
general use of, and access to, the cluster.
If you require access to a more recent version of
gcc (e.g., for the
package RcppArmadillo), it may be necessary to run
scl enable devtoolset-3 bash prior to compiling.
Off-campus network access
Some computing services at UConn are only available from on the UConn campus, including the Statistics cluster and University-hosted SFTP web storage.
To access the University's network from off-site, University affiliates can:
Members of the Department of Statistics may also SSH into the research lab Linux workstations.
The research lab contains several Linux workstations that are available for use by members of the Department of Statistics. The workstations provide shell access to a Debian-based scientific computing environment, and are accessible via SSH from off-campus.
Contact Professor Yan for access and policies.
Command-line access to UConn SFTP
To access UConn-hosted SFTP storage, first set the environment
LFTP_PASSWORD appropriately. Then, copy all
files in the local directory
/local/path/ to the remote directory
$ lftp -e "mirror -Rv /local/path /remote/path; quit;" sftp://host:22 -u $LFTP_USER,$LFTP_PASSWORD
For UConn SFTP servers,
host is something like
name.uconn.edu. Some UConn services are exclusively available from
the UConn network. The

Statistics can also
