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 OSG Consortium,
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 the project, the CHTC can also engage computing
resources from across the campus grid and the OS Pool,
an NSF-supported and expanding alliance of more than 60 universities,
national laboratories, scientific collaborations, and software developers.
CHTC users frequently obtain in excess of 150,000 free CPU hours per day from OS Pool,
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 its facilities, and
development of robust, reproducible methods for scalable computing.
