ACCESS (formerly XSEDE) and Open Science Grid Computational Resources


For researchers without access to high performance computing (HPC) resources, Information Services recommends using XSEDE (the Extreme Science and Engineering Discovery Environment, formerly known as TeraGrid). ACCESS is a collection of shared computing systems distributed across many sites nationally. These resources are supported by the National Science Foundation (NSF) and are maintained as a free national resource. Available resources include systems for large shared memory (Symmetric MultiProcessing or SMP) applications, highly scalable applications (Massively Parallel Processing or MMP), traditional clusters, and more recently high-throughput computing via Open Science Grid.
