  • Mission

    Research Computing empowers UVA researchers to achieve more with cutting-edge computational resources. Our support team strives to create innovative solutions for researchers who need help solving complex optimization, parallelization, workflow, and data analysis issues. We build and maintain the University’s best computing platforms while educating the next generation of researchers on the power of advanced computing.
  • 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.
  • 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 has access to an open Redis service in the HPC network:
  • MySQL - A basic relational database

    « Return to Databases MySQL is an open-source relational database management system. It supports standard SQL syntax and models. Some important concepts are: Tables Rows Keys Schemas Data types Selects Joins Indexes Other CRUD operations Getting Started After submitting a request for a MySQL database, a username and password be created for you, this information along with your endpoint name will be sent to you via our ticketing system. Store this information somewhere secure, and do not share this information with others. User: <your-db-username> Pass: <your-db-password> Host: <mysql-shared-endpoint-name> Port: 3306 The MySQL service is backed by a pair of servers in HA replication mode.
  • Storage FAQs

    Accidental File Deletions Why Lease Storage Leased Storage Options File Transfer 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. Research Project (leased) storage also has a .snapshot directory. Neither Research Standard (leased) nor Rivanna scratch storage is backed up in any way. Why should I lease storage? Leasing storage from Research Computing means that you do not have to run your own data server or backup system.
  • 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 "
