Eagle vs. Peregrine Supercomputer Stack-Up

See how NREL's newest high-performance computing system, Eagle, compares to its predecessor, Peregrine.

## Peak Performance

In just under a minute (54.4 seconds), Eagle can do as many calculations as there have been seconds in the universe (4.352e17 seconds).

**2.24 petaflops (million-billion calculations per second)**

**8.0 petaflops (3.5X higher performance)**

## Nodes

**Individual Servers**

If compute nodes were cars, Eagle’s cars are so much more efficient at transporting people than Peregrine's that Eagle takes 478 cars off the road.

**2,592 compute nodes**

**2,114 compute nodes**

## Processors

Modern laptops have an average of at least 4-8 cores. So, Eagle has as many cores as 19,000 cutting-edge laptops combined.

**58,752 cores**

**76,104 cores**

## Random Access Memory

**More RAM means more applications can run simultaneously.**

A typical web browser tab uses 50-200 MB of RAM. Assuming an average RAM usage per tab of 125 MB (a typical YouTube video), a computer with Eagle's system memory could have 2,368,000 loaded tabs open at the same time.

**145,408 GB**

**296,000 GB, or 296 terabytes**

## High Speed Data Storage

**Where Information is saved.**

To match the same amount of (high-speed data) storage, you'd need 28,000 500-GB laptops—which would stack 1,423 feet, or 433.8 meters, high.

**2.25 petabytes, or 2,250,000 GB**

**14 petabytes, or 14,000,000 GB**

## Network Speed

**Frequency of communication between nodes.**

If GB were people and Eagle were a grocery store, Eagle could simultaneously check out almost double the amount of people waiting in line than Peregrine could.

**56 gigabytes (GB) per second**

**100 GB per second**

## Energy-per-computation Efficiency

Using the same amount of energy as Peregrine—about the same amount needed to heat water in 1,000 coffee pots—Eagle can perform 3.5 times the number of computations.

**3.2e9 calculations per watt**

**8e9 calculations per watt**
