## Space Physics Data Repository
|
|
|
|
|
|
|
|
The Space Physics Data Repository systems were purchased with a grant from the [Roy J. Carver Charitable Trust](https://www.carvertrust.org/) and are located at the UIowa [Information Technology Facility (ITF)](https://www.facilities.uiowa.edu/building/0290).
|
|
|
|
|
|
|
|
This Space Physics Analysis Computing Environment (now, wouldn't that have been a better acronym :wink: ) will be available to support computing and data storage needs for all space physics researchers in the [Department of Physics and Astronomy](https://physics.uiowa.edu). In particular, all operations formerly supported by systems in 708 VAN are in the process of being migrated to this new facility.
|
|
|
|
|
|
|
|
The systems are co-managed by [CLAS Linux](https://clas.uiowa.edu/linux/) with direct management tasks being performed by [Larry Granroth](https://space.physics.uiowa.edu/\~ljg/) @ljg. (Dani @dgcrawfo will be added when she has time to deal with it.) The systems are fully integrated with the university Active Directory, so you can login with your hawkid and password. Note that accounts must first be enabled by the SA. Feel free to contact Larry directly with any requests or questions.
|
|
|
|
|
|
|
|
The systems initially will be configured with [Rocky Linux 8](https://rockylinux.org/) with software and file organization very similar to the [RPWG](https://space.physics.uiowa.edu/plasma-wave/) systems managed by Larry. Similarly, a login on any system will provide access to all the same software, user, and data directories. If you need to scale up to utilize more compute resources, you only need to run on multiple servers.
|
|
|
|
|
|
|
|
The new servers are sometimes referred to as "SPDR" (pronounced spider), the "ITF" systems, or the "Oakdale" systems. Interactive workstations in VAN will eventually be integrated into the SPDR environment as well.

## Servers
|
|
|
|
|
|
|
|
Capabilities include 384 cpu threads and over 1.6 PB data storage, all uniformly available via any login. Following tradition, the servers are named after planets, primarily fictional planets from Star Trek. [DCIM](https://dcim.its.uiowa.edu/cabnavigator.php?cabinetid=37), if authorized.

## Workstations
|
|
|
|
|
|
|
|
We're nearing the point where we can systematically integrate workstations into the SPDR environment as well.

## [Near-Real-Time System Status](https://fosstodon.org/tags/SPDRstatus)
|
|
|
|
|
|
|
|
In much the way we used Twitter in the past to track current system issues, we will now use the Mastodon social network link https://fosstodon.org/tags/SPDRstatus. Twitter no longer allows access to content unless you are actively logged-in, making it worthless for our purposes. One advantage of the Fediverse (Mastodon) system is that users other than me @ljg can also report status simply by beginning their post with the string "#SPDRstatus: ". (You can actually have the hashtag anywhere in the message, but let's stick to this convention to make it easier to ignore unrelated potential clashes.) Remember that this is a public forum, so don't divulge anything that would compromise security.

This explains the file system organization and how it should be used, for both project and individual use. |
