The Center for High Throughput Computing (CHTC) supports a variety scalable computing resources and services for UW-affiliated researchers and their collaborators, including high-throughput computing (HTC) and, tightly-couple computations (e.g. message passing interface, or "MPI"), high-memory, and GPUs. CHTC compute systems and personnel are funded by the National Science Foundation, the National Institutes of Health, the Department of Energy (DOE), the National Science Foundation (NSF), the Morgridge Institute for Research, and various grants from the university.

Standard access to CHTC resources are provided to all UW-Madison researchers, free of charge. Even external collaborators with an on-campus sponsor may be given access to resources. We also offer hardware buy-in options for priority access to computing capacity on a case-by-case basis, though standard access is more than sufficient for the vast majority of CHTC users.

High throughput computing (HTC) is the shared utilization of autonomous computational resources toward a common goal, where all the elements are optimized for maximizing computational throughput (Wikipedia entry). View a Windows Media movie interview with Miron Livny and other collaborators on the benefits of high throughput computing, or a Quicktime movie that highlights several applications of HTC on the UW-Madison campus. You can also listen to an interview with Miron Livny and Brooklin Gore on the impact of High Throughput Computing to campus researchers, an excerpt from the Wisconsin Institutes for Discovery: Challenge of Transdisciplinary Science pod cast series.

As part of its many services to UW-Madison and beyond, the CHTC is home to or supports the following projects:
