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](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.

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.

## 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.

## Graphical Logins
|
|
|
|
|
|
|
|
Initially all access will be using ssh (via university [VPN](https://its.uiowa.edu/support/article/1876) from off campus). Graphical logins can be accomplished using [FastX](https://clas.uiowa.edu/linux/help/fastx) or simply via "ssh -Y" from on campus. Since the university VPN has a maximum connection time of 8 hours, we're anticipating that connections via an alternative ssh port will be implemented. Let us know if you have a strong preference for x2go and we'll consider that as well.
