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

The CHTC facilitates access to an ever-growing set of resources. The UW Grid of multiple compute pools (similar to clusters)
consists of a total of nearly 18,000 cores, and continues to grow. From January 2013 through December 2013,
the CHTC provided more than 115 Million CPU hours
to campus researchers and off-campus collaborators.
As part of it's many services to UW-Madison and beyond, the CHTC is home to or supports the following projects:
- 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 (see below)
- 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.
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.
The 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.
