The NCAR Wyoming Supercomputing Center (NWSC) represents a collaboration between NCAR and the University of Wyoming. Through the
Wyoming-NCAR Alliance (WNA), 160 million core hours of the Cheyenne system, is available for Wyoming-led projects in the atmospheric, earth system, geological
and related sciences. Large allocations are overseen by the WNA Resource Advisory
Panel (WRAP); a University of Wyoming-managed process.
In addition, allocations may be given to support faculty’s integration of high performance
computing in their undergraduate and graduate courses, and to support initial code
development, experimentation, application testing and data analysis to be used to
strengthen a future grant proposal. Resources may also be made available to a small
number of projects funded by other government agencies or by the private sector.
To access the NWSC supercomputers, storage systems and data analysis and visualization
resources, users must apply for allocations. Applications are reviewed and time
is allocated according to the merit and needs of the projects and the availability
WNA Allocation basics
- Project-based. Allocations for UW’s portion of NWSC resources are allocated through
project that has a single principal investigator (PI), and may include allocations
to one or more resources (e.g. compute time, high-performance storage, data acquisition
and visualization). The PI uses the same project to request or renew an allocation,
as the focus and computational activities evolve throughout the process.
- Usage metric. The core-hour is the basic unit to measure and track the usage of NWSC
resources (including the NWSC supercomputers, high-performance storage system, data
analysis and visualization systems).
- Eligibility. All University of Wyoming faculty are eligible to apply for an allocation.
Large Allocations must be explicitly linked to funded, peer-reviewed research projects
in atmospheric, earth system, geological and related sciences (list of approved areas). An allocation request from a UW researcher can include allocations for collaborating
researchers from other US institutions who are PIs or senior personnel in the funded
project. Large Allocation requests will be evaluated semi-annually by the WNA Resource
Advisory Panel (WRAP).
- Small allocations. UW graduate students and post-docs, and UW faculty working towards
creating data, testing algorithms, etc., for a future grant proposal are eligible
to apply for a start-up allocation. No panel review is needed for small allocation
requests, and such requests can usually be accommodated within a few business days.
Small allocation requests can be made at any time using the online form available
by selecting the Small Allocation Form tab on the left.
- Educational allocations. NWSC encourages the use of high-performance computing in
undergraduate and graduate courses at UW or Wyoming Community colleges and accounts
can be provided to individual students and the instructor for assignments involving
numerical simulations, modeling, and use of recently developed computational architecture.
Faculty needing to use a NWSC resource for an undergraduate or graduate course they
are teaching should send e-mail to firstname.lastname@example.org describing the anticipated software needs, storage and computing usage at least two
weeks prior to the start of the semester the course is taught. If the anticipated
usage is more than 100,000 core-hours for the class, then WNA will want an extended
abstract describing how the resource estimate was calculated. If anticipated usage
for the class is more than 400,000 core-hours, then a large allocation request must
be submitted for WRAP review.
- Duration. Research project and small allocations are for one year. Educational allocations
are for the duration of the related class.
