Computing Facilities

Kellogg researchers have access to several different research computing systems. Here is an overview of these systems, with some guidance to help you find the right platform for the right job.

Kellogg Linux Cluster (KLC)

KLC is a set of five Linux servers.  This is a good choice for general purpose computing and for problems involving large volumes of data. Collectively the KLC contains 28 CPU cores, 7.5TB of RAM, and 160 TB of high performance storage for code and data. The cluster is available to all Kellogg researchers.

Jobs are executed automatically on the KLC when you submit them. Because this is a shared resource, we ask users to limit themselves voluntarily and not run more than 16 concurrent processes across the KLC. Please reach out to Research Support if you need more computational power than that, and we will discuss options.

 

Quest High Performance Computing Cluster

This a huge Linux cluster that currently offers more than 15,000 CPU cores across hundreds of compute nodes that are shared campus wide. This is a good option for cases when you need to run more than a few dozen concurrent processes.

Running large scale jobs on Quest typically requires that you first apply for a Research Allocation, and then you submit your jobs via bash script into a scheduling queue. Feel free to reach out to Research Support for help with either step.

 

Kellogg Application Server (KAP02)

This is a Windows server that contains many research applications and also has a volume for storing sensitive data securely. At 120 CPUs and 2 TB of RAM, it is a less powerful alternative to the Kellogg Linux Cluster. 

It is most useful for situations when you need software that is only available for Windows (such as ArcGIS) or if you need to work with data that are stored on the secure volume.

 

Kellogg Data Center (KDC02)

The KDC hosts several large scale databases in SQL Server format. For most users, your only interaction with this system will be to submit queries to these databases.

 

Computer Labs

Kellogg also maintains two computer labs, one in room 2415 of the Global Hub and one in the library at Wieboldt Hall. In the computer labs, you will find Bloomberg terminals as well as some terminals marked "special software," where you can access tools such as Datastream.
