CIBR and other shared clusters

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). Those requiring larger resources or dedicated time can participate in the purchase of future cluster equipment, and will get access to corresponding resources for the life of the cluster.

Please note that the CIBR cluster Co-op strives to maximize CPU/cost. 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 staff for cluster support at all, and Dr. Ludtke's group is handling issues on a volunteer basis.

The clusters currently in operation are:





Free CIBR Access

Paid Access



60 TB + 80 TB


25,000 CPU-hr/qtr

Chiu, Barth, Guan, Waterland


63+88 TB


25,000 CPU-hr/qtr

Chiu, Barth, 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.

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 already be familiar with the use of Linux clusters in general, and if not, to obtain assistance from their acquaintances. Occasionally CIBR may offer 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 maintained 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.

Please acknowledge the assistance from the CIBR Center by including a statement similar to the following: "We gratefully acknowledge the assistance and computing resources provided by the CIBR Center for Computational and Integrative Biomedical Research of Baylor College of Medicine in the completion of this work."
