    • Friday, October 26, 2012 - 10AM Central
      Using Globus Online to Simplify Research Data Management
      Abstract: The goal of the tutorial is to introduce researchers and systems administrators the easy-to-use Globus Online services for moving and sharing large amounts of data. Increasingly computational and data intensive science make data movement and sharing across organizations inevitable. The cloud-hosted Globus Online service makes such research tasks as easy, for example, as Netflix makes streaming movies. In this webinar, attendees will learn: how to perform fire-and-forget file transfer and synchronization between their local machine, campus clusters, regional supercomputers and national cyberinfrastructure using Globus Transfer via both Web and command line interfaces; how to store, version and share data using the new Globus Storage cloud storage service; how to integrate their security and identity infrastructure so that users may access Globus services seamlessly with their organization’s standard account (e.g., campus login via InCommon) or existing accounts with OAuth and OpenID identity providers (e.g., XSEDE, Google); and how to connect their own systems to the Globus Online services.

    • Solving the Large File Attachment Problem: Internet2's Deployment of FileSender by Randy Frank, Internet2.
      This original occurred on August 12, 2011.
      This presentation was not recorded.
      Summary:  Since the origins of the Internet/Arpanet, once a file attachment is larger than a typical SMTP server will accept (plus or minus 10MB these days), a user has been on their own to find a solution. An international consortium of NRENs, lead by AARNET, UNINETT, HEAnet and SURFNet, has been promoting a system called FileSender ( to solve this problem, and Internet2 is proposing a US deployment. The confluence of international adoption of federated authentication in the R&E community (InCommon in the US and soon REFED as an inter-federation standard) and software APIs such as the new FileAPI in HTML5 now allows for a "provisionless" service that works without any apriori provisioning of accounts or software so that users can simply store and then send to recipients a URL for file pickup, with the only requirement that their campus be a member of Internet2/InCommon. It is important to differentiate this service from various "dropbox" types of services. This is not an archival service, and files will be automatically deleted after two weeks. Because it is designed solely to solve the file attachment problem and therefore doesn't need a constantly growing backing store nor ancillary services like file backup and replication, we expect to be able to offer this service as a core network service (read: no additional charge for using this service), unlike various cloud storage offerings which most likely will need to be cost recovered.
