Citing CHTC Resources
In a Publication
This research was performed using the compute resources and assistance
of the UW-Madison Center For High Throughput Computing (CHTC) in the
Department of Computer Sciences. The CHTC is supported by UW-Madison,
the Advanced Computing Initiative, the Wisconsin Alumni Research
Foundation, the Wisconsin Institutes for Discovery, and the National
Science Foundation, and is an active member of the Open Science Grid,
which is supported by the National Science Foundation and the U.S.
Department of Energy's Office of Science.

The University of Wisconsin-Madison (UW-Madison) campus is an excellent match for meeting the computational needs of this project. Existing UW-Madison technology infrastructure supported by the CHTC can be readily leveraged, including CPU capacity, network connectivity, storage availability, and middleware connectivity. The UW-Madison has invested in the CHTC as the primary provider of shared, computing resources to campus researchers. All standard CHTC services are provided free-of-charge to UW-Madison researchers, their projects, and collaborators. But perhaps most important, the UW-Madison has significant staff experience and core competency in deploying, managing, and using computational technology.
For high throughput computing (HTC) capability, UW-Madison supports more than a dozen compute clusters across campus, which are managed via the HTCondor software developed by the CHTC; therefore, these clusters are linked together to share resources via a widely adopted distributed computing technologies. CHTC's dedicated HTC cluster includes GPUs and individual servers with multiple TB of memory. For high performance computing (HPC) capability (large, tightly-coupled work), the CHTC also maintains a shared-use cluster of approximately 7,500 tightly-coupled cores. The configuration of CHTC resources has also been informed by collaborations with fellow computing centers at other campuses through the NSF-funded ACI-REF and CaRCC projects.
Together, CHTC-supported resources provided over 365 million CPU hours in 2020, and individual users regularly obtain in excess of 10,000 CPU hours per day. Temporary storage space for large files can support up to hundreds of terabytes of total working data. Should these resources not be sufficient for your project, the CHTC can also engage computing resources from across the campus grid and the Open Science Grid (OSG), an NSF-supported and expanding alliance of more than 60 universities, national laboratories, scientific collaborations, and software developers. We frequently obtain in excess of 150,000 free CPU hours per day from OSG, with individual users achieving up to 100,000 CPU hours per day, across all of these.
The CHTC is home to over 20 full-time staff with a proven track record of making compute middleware work for scientists. Far beyond just being familiar with the deployment and use of such software, UW staff has been intimately involved in its design and implementation. Dedicated Research Computing Facilitators are available to provide training to all CHTC users and are available to consult on computational practices for achieving the best scientific throughput. As always, CHTC will be happy to provide consulting to ensure optimal use of our facilities, and development of robust, reproducible methods for scalable computing.
