  • Redis - A Key/Value Store

    « Return to Databases redis is an in-memory, key/value store. Think of it as a dictionary with any number of keys, each of which has a value that can be set or retrieved. However, Redis goes beyond a simple key/value store as it is actually a data structures server, supporting different kinds of values. Some fundamental concepts: Can be used as a databse, cache, or message broker Supports multiple data types and structures Built-in replication Keys can be up to 512MB in size /userinfo/howtos/general/databases/ Getting Started Rivanna nodes can connect to external Redis databases hosted in Kubernetes or a public cloud (AWS, Azure, GCP, etc.

  • Integrated Sensor Networks in Arctic Alaska

    Understanding the Changing Natural-Built Landscape in an Arctic Community Navigating the New Arctic (NNA) is one of The National Science Foundation’s 10 Big Ideas. NNA projects address convergence scientific challenges in the rapidly changing Arctic. Arctic research is needed to inform the economy, security and resilience of the Nation, the larger region and the globe. NNA empowers new research partnerships from local to international scales, diversifies the next generation of Arctic researchers, enhances efforts in formal and informal education, and integrates the co-production of knowledge where appropriate. This award fulfills part of that aim by addressing interactions among social systems, natural environment, and built environment in the following NNA focus areas: Arctic Residents, Data and Observation, Education, and Resilient Infrastructure.
  • COVID Saliva Testing

    In cooperation with the UVA Saliva Testing Lab, the UVA Health System, and the Virginia Department of Health, the “Be SAFE” saliva testing program was launched in late 2020. Now a retired project, Be SAFE used saliva samples to detect the COVID-19 virus through a diagnostic PCR test. Research Computing provided computational, storage, and data integration expertise to this project.
  • Storage FAQs

    Accidental File Deletions Why Lease Storage Leased Storage Options File Transfer with Globus Permission Denied Error with Globus Help! I deleted my files accidentally! What can I do? Your home directory contains a hidden directory .snapshot which is not visible even with ls -a. Change into that directory to find timestamped versions of your home directory. Snapshots are created once per day. For GPFS Research Project (leased) storage, the directory is /gpfs/gpfs0/project/.snapshots. For non-GPFS Research Project storage, the directory is /project/.snapshot. Neither Research Standard (leased) nor Rivanna scratch storage is backed up in any way. Why should I lease storage?
  • Graphical SFTP/SCP Transfer Tools

    Several options are available to transfer data files between a local computer and Rivanna through user-friendly, graphical methods. Off Campus? Connecting to Rivanna from off Grounds via Secure Shell Access (SSH) or FastX requires a VPN connection. We recommend using the UVA More Secure Network if available. The UVA Anywhere VPN can be used if the UVA More Secure Network is not available. Only Windows and Mac OSX operating systems are supported by the Cisco client provided by ITS. Linux users should refer to these unsupported instructions to install and configure a VPN. The More Secure Network requires authentication through Duo; users should follow the instructions on the dialog box to enter "
