When the RSS resources are not enough to meet your research needs - there are great tools available through the NSF. One of the most popular and successful of these is the XSEDE program.
What is XSEDE?
The Extreme Science and Engineering Discovery Environment (XSEDE) is a single virtual system that scientists can use to interactively share computing resources, data and expertise. If you are a US-based researcher and currently use, or want to use, advanced research computing resources and services, XSEDE can help. Whether you intend to use XSEDE-allocated resources or resources elsewhere, the XSEDE program works to make such resources easier to use and help more people use them.
How to Get Started?
Step 1: Get an Account
Step 2: Request an Allocation
After you get a profile setup with XSEDE, the next step will be to review and request access to resources. To do this, you will login through your XSEDE portal and look for the "Submit/Review Request" link under the Allocations tab:
Step 3: Enable Multi-Factor Authentication
After setting up your account and receiving the confirmation and welcome e-mail introducing your XSEDE resources - you will need to enable MFA using a secondary device. XSEDE is currently using Duo - more information and instructions for how to install on your device are included here
Step 4: Login to the XSEDE SSO Hub
Following the successful setup of MFA - you are ready to access your XSEDE resources. A great way to do this is by using the XSEDE SSO hub Using a ssh host - you can simply login to the hub by running: 'ssh -l xsedeusername login.xsede.org'
From there you can view all of your allocations by running: 'xsede-gsissh-hosts'
To login to a particular resource - run 'gsissh host' for example:
