High Throughput Computing is a collection of principles and techniques which maximize the effective throughput of computing resources towards a given problem. When applied for scientific computing, HTC can result in improved use of a computing resource, improved automation, and help drive the scientific problem forward.

The team at CHTC develops technologies and services for HTC. CHTC is the home of the HTCondor Software Suite which has over 30 years of experience in tackling HTC problems; it manages shared computing resources for researchers on the UW-Madison campus; and it leads the OSG Consortium, a national-scale environment for distributed HTC.

The HTCondor Software Suite (HTCSS) provides sites and users with the ability to manage and execute HTC workloads. Whether it’s managing a single laptop or 250,000 cores at CERN, HTCondor helps solve computational problems through the application of the HTC principles.



UW Research Computing

CHTC manages over 20,000 cores and dozens of GPUs for the UW-Madison campus; this resource, which is free and shared, aims to advance the mission of the University of Wisconsin in support of the Wisconsin Idea. Researchers can place their workloads on an access point at CHTC and utilize the resources at CHTC, across the campus, and across the nation.

Research Facilitation

CHTC’s Research Facilitation team empowers researchers to utilize computing to achieve their goals. The Research Facilitation approach emphasizes teaching users skills and methodologies to manage & automate workloads on resources like those at CHTC, the campus, or across the world.


As part of its many services to UW-Madison and beyond, the CHTC is home to or supports the following Research Projects and Partners.


The OSG is a consortium of research collaborations, campuses, national laboratories and software providers dedicated to the advancement of all of open science via the practice of distributed High Throughput Computing (dHTC), and the advancement of its state of the art. The OSG operates a fabric of dHTC services for the national science and engineering community and CHTC has been a major force in OSG since its inception in 2005.
