Linux Community Servers (LINCOMM) FAQ
A description of the Linux Community Servers (LINCOMM) for use by AAE faculty & students
What is LINCOMM?
LINCOMM is an abbreviation of Linux Community Servers. These servers are a collection of Linux-based (AlmaLinux 8) machines that are designed specifically for running code. The user interface is a text-based command line system, specifically Bash shell.
What is the purpose of LINCOMM?
LINCOMM's purpose is to provide access to statistical programs such a R, Stata, Python, and MatLab for code/jobs that require more memory or computing time.
Who has access?
All AAE faculty, staff and graduate students have access to LINCOMM. Undergrad students can be granted access with specific permission from AAE professors.
How do I connect to LINCOMM?
How many LINCOMM servers are there?
Currently there are 4 LINCOMM servers (lincomm1.aae.wisc.edu, lincomm2.aae.wisc.edu, lincomm3.aae.wisc.edu, lincomm4.aae.wisc.edu). lincomm1-3 are general use servers, while lincomm4 is reserved for use with sensitive or restricted data.
What's the difference between the LINCOMM servers?
Currently there is no difference between the LINCOMM servers. They are running identical software on very similar hardware. Some servers have more RAM than others. If you run into problems with RAM usages, please contact ITSC staff.
Which LINCOMM server should I connect to?
When you connect to LINCOMM using the cluster address (lincomm.aae.wisc.edu), you'll be directed to the least busy of the three general use LINCOMM servers automatically. This will spread users among all the servers and help avoid situations where one server is much busier than another.
If you wish to reconnect to a session already in progress (for instance, you have a job running), you should connect to the server where you had previously connected.
How do I use LINCOMM?
You can read a very BRIEF introduction at Using LINCOMM . However, it highly recommended to search out a general Linux/Unix tutorial online.
