System Resource Allocation Requests

For system resource allocations, learn about the high-performance computing (HPC) annual call for requests, and out-of-cycle and pilot project requests.

The deadline for Fiscal Year (FY) 2025 requests has been extended to June 21, 2024.

Fiscal Year 2025 Annual Call for Allocation Requests

The National Renewable Energy Lab (NREL) provides high-performance computing and related capabilities to support the mission of the Department of Energy (DOE) Office of Energy Efficiency and Renewable Energy (EERE). EERE's mission is to create and sustain American leadership in the transition to a global clean energy economy. Research and development projects in energy efficiency, renewable energy, and sustainable transportation that are funded by EERE Offices or aligned with the EERE mission are eligible to utilize these resources. EERE high-performance computing focus areas include energy systems integration, materials science, forecasting, manufacturing, and fluid dynamics. Due to the increase in capacity in FY 2025 outlined below, EERE may additionally grant allocations to mission-relevant computing projects that are supported by industry collaborators or university partnerships.

NREL runs an annual open call on behalf of EERE for research and development projects to request use of a defined quantity, or allocation, of the compute resources at NREL. This notification serves as the announcement of this call for allocation requests. The allocation period of performance runs from Oct. 1, 2024, through Sept. 30, 2025.

Resources will be allocated on NREL's new third generation supercomputer, Kestrel. Kestrel features a heterogeneous architecture consisting of Standard compute nodes (CPU-only nodes) and Accelerated nodes (GPU nodes) and represents a significant expansion in computing capability at 44 petaflops. Resources to be allocated on Kestrel for FY25 include 191 million "Allocation Units", or AUs on standard compute nodes; 109 million AUs on accelerated nodes; 30 petabytes of shared data storage and up to 60 petabytes of long-term data storage. Standard compute nodes provide 10 AUs per node hour and accelerated compute nodes provide 100 AUs per node hour. Kestrel standard compute nodes have two Intel Sapphire Rapids 52-core processors. Kestrel accelerated nodes have four NVIDIA H100 Tensor core GPUs and two AMD Genoa 64-core processors.

Allocation requests must be completed and submitted by June 21, 2024.

Learn more about the DOE Office of Energy Efficiency and Renewable Energy. For additional information about Kestrel, see Kestrel System Configuration. For additional information about Allocation Units, see System Resource Allocation Units.

Users are encouraged to submit requests for projects where a proposal has been submitted or is pending, as well as ongoing projects. Requesting an allocation will not affect the funding status of any submitted or pending proposals. Allocation requests must be completed and submitted by June 21, 2024. 

Users should request an NREL account by May 31, 2024 to expedite submission. Users experiencing difficulty accessing the online request form may contact for alternate submission procedures.
