QERM simulation servers

In 2015, QERM received a technology grant from the Student Technology Fee committee for three high-performance remote computing servers, to help facilitate QERM student research. The servers are particularly useful for running simulations, computationally-expensive code, and parallel processing. Each server comes with two 2.5GHz processors with 24 cores, 256GB of RAM, and 1TB of disk space for TEMPORARY data storage. More complete specs on the servers can be downloaded here. (Note: this document describes the specs of an individual server; we have three.)

The servers are freely available for use to all students. To gain access, contact SEFS IT at sefshelp@uw.edu, and they will add you to the SEFScompute email list, which then grants you access to the servers.

Connecting to the servers

There are three different servers, Pilchuck, Skykomish, and Snoqualmie. Their addresses are:

pilchuck.sefs.uw.edu

skykomish.sefs.uw.edu

snoqualmie.sefs.uw.edu

To gain access, contact SEFS IT at sefshelp@uw.edu, and they will add you to the SEFScompute email list, which then grants you access to the servers.

Mac users

On campus

Open Microsoft Remote Desktop and create a new connection. In the PC name field, enter any one of the three server addresses above. In the User name field, enter NETID\yournetid. In the Password field below that, enter your netid password. You're good to go!

Off campus

Set up a VPN connection to UW, using these instructions. Once you have set up the connection, proceed to connect to the servers through Microsoft Remote Desktop.

PC users

On campus

Open Remote Desktop Connection, and click on Show Options. In the Computer field, enter any one of the three server addresses above. In the User name field, enter NETID\yournetid. Click the Connect button, where you will be prompted to enter your netid password, with the option for saving it for future use. You're good to go!

User tips

Finding software programs

Once you're in, clicking the start menu will give you the horrendous, non-intuitive Windows-8-ish desktop. Click the down arrow at the bottom-left to find programs. Press Escape to get back to the desktop.

Current list of available software

Here is a list of software programs available on the servers. If you have other software needs, please contact SEFS IT at sefshelp@uw.edu.

  • ADMB
  • ArcGIS
  • CircuitScape
  • FVS
  • JAGS
  • Java
  • PyScripter
  • R
  • RStudio

Accessing data

Under This PC's Network Locations, there is a network connection to main.sefs.uw.edu, a server that many labs in SEFS use for data storage. A network connection can also be made for other data servers that are accessible through the NETID system, such as those used by labs in SAFS. Click on This PC, and then navigate to the Computer menu and select Map network drive. From here, enter the address of the drive you want to connect to. I (Scott), for example, can access data I have stored on the CSDE terminal servers by following these steps and entering the address \\netid.washington.edu\csde\homes\user2\rinnan. If you don't know the address of your server, try getting in contact with the administrator of your server to find the answer, not SEFS IT.

Saving data

The disk space on the servers is SCRATCH SPACE ONLY, and is not backed up anywhere. It is HIGHLY recommended that you save your results to another location, and only use the scratch space for temporary work as necessary. Please be mindful that this disk space is shared with all other users, and there is a limited amount to go around. If you want to save things temporarily, create a folder for yourself at D:\Workspace\username, and make sure to DELETE FILES WHEN YOU ARE FINISHED. I (Scott), for example, write my R code so that files are saved directly to my space on the SEFS server at \\main.sefs.uw.edu\main\Space\Lawler\Shared\Scott.

If you are looking for a place to store code, data, and results that will also be available from your personal computer, note that all UW students get 30 GB of free storage on their U Drive. This is also automatically backed up. If you have activated this service, your own drive is automatically mapped when you log on to the servers.


Good luck, and happy coding!
