Center for High Throughput Computing

The Center for High Throughput Computing (CHTC) offers a variety of large-scale computing resources and services for UW-affiliated researchers and their collaborators, including classically-defined high-throughput computing (HTC) and high-performance computing (HPC) resources. CHTC services and hardware are funded by the National Institute of Health (NIH), the Department of Energy (DOE), the National Science Foundation (NSF), and various grants from the University itself.

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.

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 it's many services to UW-Madison and beyond, the CHTC is home to or supports the following projects:

HTCondor project

The HTCondor project provides the globally-used HTCondor software that powers the CHTC's HTC resources. HTCondor enables the CHTC to maximize job throughput for many simultaneous users, each with different needs. It supports complex workflows, the ability to take checkpoints and then resume jobs, and it enables access to additional computing resources across the globe, like the Open Science Grid.

UW Build and Test Lab

The UW Build and Test Lab (BaTLab) is a multi-platform facility that promotes continuous building and testing of software, and is available to the public. HTCondor is built in the BaTLab, toward our goal of deploying error-free, high quality software for the CHTC.

Open Science Grid

The Open Science Grid (OSG) is a high-throughput computing infrastructure that supports science across the country. It is an expanding alliance of more than 100 universities, national laboratories, scientific collaborations, and software developers, all combining their computational resources with one another for maximal throughput of large-scale computational work. CHTC users have automatica and FREE access to OSG's considerable computing and storage resources.

NEOS Online Optimization Service

NEOS Online Optimization Service is a publicly-available, high-throughput computing infrastructure that provides solvers for a variety of optimization problems. It also provides background information on the field of optimization, in general, as well as case studies that provide an understanding of optimization problems and approaches to solving them.
