ARC user support¶
About ARC¶
Welcome to the ITS Advanced Research Computing (ARC) user support web site.
ARC provides support and referral for many kinds of research computing and many aspects of research computing, from programming to data storage services. More information about ARC can be found at the ARC website. This site aims to help you once you have found us.
About this site¶
There is a Table of contents for each page on the right, and a menu of pages on the site to the left.
If you do not see a menu to the left, please click on the so-called
hamburger icon 
in the top left corner of the page, which will drop the menu down.
Expanding the width of your browser may also make the menu visible all
the time. Click on the chevron (>) to the left of a topic to display
the pages under that topic.
Some pages will have text in hidden blocks to increase the readability of the main page.

Help topics¶
The following are brief summaries of what you will find on the pages listed in the menu.
The first thing we want to make sure you know is how to get hold of us should you have questions for which you cannot find an answer here. The short answer is that the best way to reach us is with e-mail to arcts-support@umich.edu. We list topics with which we can help and how best to contact us about them on the Getting help page.
If you are new to the University of Michigan, or are wondering when and why you might use ARC services, please use the When to use ARC in the menu for a page of situations in which we may be able to help.
If you are all ready to get started but are new to cluster computing, please see our glossary of terms at the Cluster terminology page.
If you are getting started on an ARC run cluster, see the topics under ARC cluster help, of which there are several. Click the > icon in the menu to get a listing of the subtopics on using the ARC clusters.
XSEDE is an NSF funded program that provides a variety of very large computing clusters, as well as a virtual machine environment. Please see the XSEDE resources page for information about XSEDE and what kinds of help we can provide.
Open Science Grid (OSG) is also an NSF funded program that provides high throughput computing for people with modest tasks that they need to run hundreds to hundreds of thousands of times. See the Open Science Grid page for more information about OSG and how we can help you use it.
ARC consulting offers some consulting on data science and machine learning, and we can discuss your problem, whether of research design, programming, or appropriate computational or storage requirements and refer you to others if we cannot provide answers ourselves.
