Welcome Supercomputing 2018 users! This sandbox is no longer active but the page is left for reference. If you have questions about OSiRIS please email osiris-help@umich.edu.

OSiRIS has configured a virtual organization ‘sandbox’ available to anyone at SC18 on SCInet. The storage used by this VO has a Ceph cache tier overlaid. This cache is hosted on the hardware in the UM and MSU combined booth:

There are two available options for accessing OSiRIS storage at SC18. The maximum available quota for each is 400TB (separate quotas). Of that, 50TB will fit into local caching pools. No data will be kept after the conference.

NFS Gateway

NFS gateway using Ganesha-NFS (using a Docker container).

The server is configured to squash all users to a single test user for purposes of this demo. It is only accessible from SCInet VLANS. To mount create directory of your choice and:

mount -t nfs sc-stor-nvm01.osris.org:/sc18 /sc18osiris

S3 Gateway

S3 Ceph Radosgw:

https://sc-stor-nvm01.osris.org:8443

OR

http://sc-stor-nvm01.osris.org:880

This works slightly differently and requires enrollment in OSiRIS.

  1. Visit comanage.osris.org/enroll and login with your institutional credentials
  2. Fill in the brief form, and be sure to choose SC18 for the "COU" field on the form (first field).
  3. Respond to confirmation email
  4. Wait for 2nd email indicating approval
  5. Visit again https://comanage.osris.org or refresh the page.
  6. Obtain S3 credentials by clicking on "Person Menu" at upper-right of page and choosing "My OSiRIS Tokens"
  7. More details including screenshots in our documentation (you can use the endpoints documented there to see the penalties imposed by using the SC18 cache tier from distant locations)

If you are unable to complete the enrollment process because of a problem or if you do not belong to any of the available institutions please email us with subject “SC18 Sandbox” and credentials can be manually created for you.
