High Performance Compute and Storage

Cheaha is a campus HPC resource dedicated to enhancing research computing productivity at UAB. Cheaha is managed by UAB IT’s Research Computing team and is available to members of the UAB community in need of increased computational capacity. Cheaha supports high-performance computing (HPC) and high throughput computing (HTC) paradigms. Cheaha is composed of resources that span data centers located in the UAB IT data centers in the 936 Building and the Rust Computer Center. UAB IT in open collaboration with community members is leading the design and development of these resources. UAB IT’s Infrastructure team provides operational support and maintenance of these resources.

Visualization - Virtual Labs

Virtual Network Computing (VNC) is a cross-platform desktop sharing system to interact with a remote system's desktop using a graphical interface. This page covers basic instructions to access a desktop on Cheaha using VNC. These basic instructions support a variety of use-cases where access to graphical applications on the cluster is helpful or required. If you are interested in knowing more options or detailed technical information, then please take a look at man pages of specified commands.

Research Collaborations/Consulting

The mission of Research Computing staff is to support and advance research discoveries at UAB through partnerships with faculty and research groups. Our research scientists can collaborate with faculty on grant proposals and support them by providing cyberinfrastructure solutions for research projects.RC staff can also take on roles in proposals including (but not limited to) consulting on better utilization of high performance computing, providing data-intensive and high-throughput computing resources, improving scientific workflows, leading software design and development, creating, managing, and publishing large data collections, creating educational and outreach visualizations, designing and/or deploying scientific gateways, and assisting with acquisition and/or access to local, regional, and national advanced cyberinfrastructure resources.

Training: The Research Computing staff provides advanced support and training for the user community. User groups meetings and training sessions are organized on a regular basis. Workshops and seminars from industry partners such as the Mathworks (creators of MATLAB) and NVIDIA are organized by research computing. Several graduate courses use Research Computing facilities to prepare students to use the cluster and for their research activities.

Science DMZ/High speed network

The Science DMZ is a network built at or near the campus or laboratory's network perimeter. It is designed such that the equipment, configuration, and security policies are optimized for high-performance scientific applications. Research Computing is developing UAB's Science DMZ. This networking infrastructure is aimed at providing a dedicated, high-speed network to support acquisition and sharing of large research data sets, a crucial resource in the era of Big Data. The design supports fast data transfers between research laboratories and computational facilities. It leverages UAB's Internet2 connection (100 gbps) for high speed transfers to data national and international data repositories. The Science DMZ improved the network connectivity on campus ten fold while providing a "friction-free" pathway to access external data repositories as well as computational resources such as XSEDE and Open Science Grid. Network performance is monitored using perfSonar and high-speed data transfer are supported through data transfer nodes (DTN's). This is an infrastructure to enable multidisciplinary collaboration within UAB as well as with collaborators outside UAB.
