Kestrel's GPU-accelerated nodes

Feb. 15, 2024
Last week, Kestrel's GPU-accelerated nodes arrived, and the Kestrel team, alongside Hewlett Packard Enterprise engineers, began installing them in the Energy Systems Integration Facility’s HPC data center. The GPU nodes will play a critical role in supporting advanced applications and technologies in artificial intelligence and machine learning in energy research. When the installation is complete, Kestrel will have 132 GPU nodes added to the existing CPU capacity, with each GPU node hosting 4 NVIDIA H100 GPUs. With Kestrel soon to be at its full capacity of 44 petaflops, researchers will be empowered to tackle more complex, data-centric research questions towards a renewable and sustainable future.

There are a lot of numbers and terms when it comes to the new Kestrel HPC system. 44 petaflops; 2,456 nodes; 95 petabytes; we could go on. Beyond the numbers, Kestrel represents a significant expansion in the capabilities and computing power for NREL and its partners at the U.S. Department of Energy and beyond. With faster, more robust computing capabilities, Kestrel will allow energy research at NREL to soar to the next level.

In a short video, hear why Kestrel’s impressive speed really matters, according to Surendra Sunkari, NREL HPC engineer and Kestrel technical lead.

Today was a very exciting day for Kestrel! U.S. Secretary of Energy Jennifer Granholm visited the NREL campus to help showcase and celebrate the laboratory's new campus expansion projects. Among many exciting activities of the day, the secretary joined NREL staff and representatives from Hewlett Packard Enterprise to sign the supercomputer!

"What an amazing opportunity to have Secretary Granholm celebrate Kestrel with us," said Kristin Munch, NREL's Advanced Computing laboratory program manager. "Our team was honored to have this opportunity to showcase Kestrel and celebrate the next chapter of supercomputing capabilities for NREL and the U.S. Department of Energy. We're grateful to the many NREL staff, media, and distinguished guests who participated in today's activities."

Thank you to Secretary Granholm and the many other distinguished visitors who visited NREL today to celebrate Kestrel and other campus expansions. Learn more about NREL's campus expansion.

44 petaflops.
95 petabytes of data storage.
604 terabytes of total memory.
Kestrel will make our research faster and more efficient than ever. See how Kestrel stacks-up by the numbers.

Kestrel is now in the final stages of hardware installation, and the team is working out final network configurations and access points for the compute and storage parts of Kestrel as the whole system gets integrated into the Energy Systems Integration Facility data center. "This part of the installation is critical as we make sure all the hardware components are working as expected and that Kestrel's internal network is configured as well as its connectivity to the rest of the data center. Taking the time to get things right now will make all the difference down the line," said Surendra Sunkari, the Kestrel installation technical lead.

Kestrel is now fully cabled, and all compute nodes are connected to the high-speed network and storage. The doors were hung, and the graphics were applied. Kestrel is taking shape!

Kestrel's CPU nodes are now placed in NREL's HPC Data Center in the Energy Systems Integration Facility data center, with preliminary power and cooling tests ongoing including flowing water from the facility to the cooling distribution units. The storage dedicated to Kestrel has also moved in, with nearly 9,000 hard drives installed last week. The team is starting to cable the network to connect all of Kestrel's components and performing component level diagnostics.

It's here! On a snowy and chilly Colorado morning, the trucks arrived right on schedule to deliver the Kestrel elements to NREL's main gate.

After initial safety briefings, the operations team got right to work to move equipment from the trucks into NREL’s data center, the future landing place for Kestrel.

The team will continue building Kestrel over the coming months, conducting further software testing, and incorporating the next equipment deliveries to power our most comprehensive and transformative energy solutions yet.

Yesterday, Encore Electric wrapped up the final wire installation, providing almost 2 megawatts of electrical distribution to a single row of computing equipment. Roy Fraley and Chris Burke are now able to install a basket tray that will allow us to connect the storage system to the compute cabinets.

"Systems of the size and scale of Kestrel don't just plug into the wall like your laptop, so kudos are in order to Site Ops, ESIF Ops, Encore Electric, and the ACO team, all doing a great job getting the data center prepared," explains Aaron Andersen, group manager of Advanced Computing Operations with NREL's Computational Science Center.

Several team members visited the Hewlett Packard Enterprise (HPE) factory in Wisconsin in mid-February to get a final review of the Kestrel Phase 1 before it ships to NREL. The team was able to check out the facility connections for the power and cooling infrastructure on Kestrel and validate the system's operations in HPE's data center, including logging in to the system for the first time.

"Getting an early look at these connections and verifying the power components while in factory is critical to ensuring a smooth install when it arrives at NREL," explains Roy Fraley, high-performance computing data center engineer with NREL's Computational Science Center.

At last! Kestrel is about to hatch…or rather, its baby sibling, Eyas.

The first pieces of the "test and development" system, Eyas, arrived at NREL in late December and the team has now gotten to work. Eyas is a much smaller system that will help NREL's team of computer scientists prepare for the large-scale installation and operations of Kestrel before it arrives in March. Eyas will help the team improve cyber-security posture, test software, and prepare the environment ahead of the full Kestrel build.

The system team is elated to finally have hands on the first components of the new system.

"Eyas has proven exceptionally valuable as we have been able to identify some issues in the software stack, correct those and provide hands on training to staff ensuring that common NREL models and applications are ready for the Kestrel system", said Aaron Andersen, group manager of Advanced Computing Operations with the Kestrel project.

Not the news we wanted! The Kestrel team was notified in December 2022 that the delivery of the central processing unit (CPU) nodes for Kestrel would be delayed due to supply chain disruptions. This delay will postpone Kestrel's availability for use until mid-summer 2023.

NREL's incoming high-performance computing system—Kestrel—will have superior advanced supercomputer capabilities compared to its predecessor, Eagle. For example, if the two were side by side on subway tracks, Kestrel would travel 5.5 times faster than Eagle.

See more real-world examples on how the Kestrel versus Eagle supercomputer stack-up.
