XSEDE is a consortium of multiple supercomputing partner institutions including the Texas Advanced Computing Center [TACC], San Diego Supercomputing Center [SDSC], Georgia Tech [Gtech], National Institute for Computational Sciences [NICS], Pittsburgh Supercomputing Center [PSC], and others. A nice summary of site resources can be found here. Each site may have multiple clusters available serving different purposes so please review which site is most appropriate for the research you're trying to do.
If you're interested in exploring the use of XSEDE resources please contact the XSEDE representative at Harvard Medical School by e-mailing Jason Key. You can request an account through the link at the XSEDE User Portal or by the direct link button below to the same page.
After reviewing the XSEDE resources and consideration of if it would be beneficial for your research you can apply for an account through the XSEDE User Portal.
You can log into specific XSEDE sites directly using your XSEDE userid and corresponding server. However, XSEDE also has a single-point login node
login.xsede.org which provides access to all the sites. I applied for my XSEDE account using my eCommons ID so it's easier for me to remember when logging in, there's an example below.
$ ssh email@example.com firstname.lastname@example.org's password: Last login: Thu Sep 25 13:07:57 2014 from ritg-pat.med.harvard.edu Welcome to the XSEDE Single Sign-On (SSO) Hub! Your storage on this machine is limited to 100MB. You may connect from here to any XSEDE resource on which you have an account. To view a list of sites where you actually have an account, visit: https://portal.xsede.org/group/xup/accounts Here are the login commands for common XSEDE resources: Blacklight: gsissh blacklight.psc.xsede.org Darter: gsissh gsissh.darter.nics.xsede.org Gordon Compute Cluster: gsissh gordon.sdsc.xsede.org Gordon ION: gsissh gordon.sdsc.xsede.org Keeneland: gsissh gsissh.keeneland.gatech.xsede.org Lonestar: gsissh lonestar.tacc.xsede.org Mason: gsissh mason.iu.xsede.org Maverick: gsissh -p 2222 maverick.tacc.xsede.org Nautilus: gsissh gsissh.nautilus.nics.xsede.org Open Science Grid: gsissh submit-1.osg.xsede.org Stampede: gsissh -p 2222 stampede.tacc.xsede.org Trestles: gsissh trestles.sdsc.xsede.org Contact email@example.com for any assistance that may be needed.

Once logged in you can see all the XSEDE sites and corresponding commands to access them from the XSEDE login node. So, for example, if I wanted to connect to the Grodon super computer at SDSC I could use the supplied command of
gsissh gordon.sdsc.xsede.org as indicated in the welcome message. I've shown the example below, please note that each individual XSEDE site has its own resources rules so I would encourage you to do your research as to which site is most appropriate for the work you're trying to do.

If you have any questions regarding XSEDE specifically you can e-mail them directly for technical support. At Harvard Medical School you're welcome to reach out to our XSEDE campus champion, Jason Key or the research computing group to discuss more scientific questions.
The XSEDE campus champion at Harvard Medical School is Jason Key, the director of the structural biology grid. Questions about XSEDE can be directed to him here.
If you're affiliated with Harvard Medical School and have used XSEDE in your research we'd be interested to hear about it and profile it for the local community.
