CIBR Cluster Co-op

Please note that the CIBR cluster Co-op strives to maximize CPU/cost. On most clusters, staff support is one of the largest expenses. So, while we routinely support issues with hardware, queuing system, operating system problems, etc. we have absolutely no applications support staff. At present, we actually have no BCM support for cluster support staff at all, and Dr. Ludtke's group is handling issues as a community service.

CIBR and a number of specific faculty have sponsored the purchase of several clusters managed for shared use by faculty. CIBR faculty may request moderate allocations for free, as a benefit of CIBR membership (which is free). Faculty who contributed funds directly to the purchase have larger guaranteed allocations.

The clusters currently in operation are:





Free CIBR Access

Paid Access



60 TB + 80 TB


25,000 CPU-hr/qtr

Ludtke, Guan, Waterland


63+88 TB


25,000 CPU-hr/qtr

Wensel, Ludtke, Guan



350 TB Raid6x2


upon request


Reliable storage (backed up RAID6) for inactive data which will still be needed on the clusters. This storage array is available upon request to users of any of the clusters, but is directly accessible only from the clusters to discourage people for using it for general lab backup purposes. Please note that the primary active storage on each cluster is NOT backed up in any way. It is a RAID6 volume, which gives it good reliability, but every 4-5 years we experience some sort of failure.

Requesting Access

Free cluster accounts must be requested directly by a PI who must be an established member of CIBR, and such accounts will charge against that PI's allocation. We may discuss your intended use for the cluster before granting accounts to insure that it will not interfere with paid cluster users.

Cluster Usage

Each cluster has independent user accounts, as different faculty contributed different amounts to each. Please click on one of the links above for detailed policies and procedures for each cluster

Individual users are expected to be familiar with the use of Linux clusters in general, and if not, to obtain assistance from their acquaintances, rather than learning by trial and error. Occasionally CIBR offers a workshop to help familiarize people with cluster computing, which will be advertised via normal CIBR mechanisms.

All of the clusters run some version of CentOS Linux. We do not provide any commercial software, but most standard open-source tools are installed, and users are welcome to install commercial or free software within their own accounts. BCM's site license for Matlab is usable on the cluster, but must be installed/licensed in the user's account, and there are some setup issues. Contact Larry Mayran about this for details. We may also be able to install other open-source software system-wide, if you have such a need, please ask.

Details on some of the open-source software we have made available for users is on the Software page.

There is a CIBR Cluster Google Group/Mailing List (!forum/cibrcluster) which is used for announcements of outages, problems, policy changes, etc. We strongly recommend all CIBR Cluster users join.
