XSEDE Banner

The Extreme Science and Engineering Discovery Environment (XSEDE) is a single virtual system that scientists can use to interactively access computing resources from nations leading supercomputing centers.   XSEDE resources range from High Performance Computing, High Throughput Computing, Visualization, Storage Resources, and Services.

VELA vs XSEDE: When to use VELA or XSEDE

Georgia State’s VELA provides researchers immediate access and a better platform for development, but the resources that VELA offers may not be enough for a given large-scale problem.  XSEDE provides vast resources that would allow a researcher to accomplish their goal, but the wait time before the job starts are longer.   Therefore, VELA should be used for smaller jobs (not more than 120 cores), and XSEDE should be used for larger jobs.  Also, VELA may be used for testing codes before scaling the jobs out to XSEDE resources.

Georgia State receives resource allocations through the XSEDE’s Campus Champion program.  For a list of various resources available to Georgia State, click the link below.  To get started with XSEDE, contact Suranga Edirisinghe or Semir Sarajlic.
