Excerpt

What is XSEDE? The Extreme Science and Engineering Discovery Environment (XSEDE), funded by the NSF (National Science Foundation) is the next generation replacement for TeraGrid. The goal is to provide access to super computer resources for US based researchers as well as expand into new avenues such as research collaboration. Training, Education, and Outreach are a significant component of Xsede and there are many fantastic resources available.

What is available? XSEDE provides access to a number of very large systems, many with hundreds of thousands of cpu cores, high speed interconnections and fast storage. High memory, shared memory systems are available along with a large number of GPGPU (General Purpose Computation on Graphics Processing Units) and acceleration units such as those available from Nvidia, AMD and Intel MIC (Many Integrated Core). Rather than duplicate the list, please see the following https://www.xsede.org/web/guest-staging/resources

When to apply? The application period for XSEDE resources is quarterly so apply as early as possible.

How does Tufts participate in XSEDE? Currently RGTS (Research and Geospatial Technology Services) aids in dissemination of information regarding available Xsede resources, how to apply for allocations and basic information regarding access, usage and file transfer. As part of Tufts connection to Internet2 we have high speed access to systems on Xsede.

How do I chose between the Tufts HPC (High Performance Compute) cluster and XSEDE? The decision is not mutually exclusive as both clusters are general purpose clusters running a wide variety of software for a an equally broad user base. Typically if you are running custom code it should be compiled individually for each system.
