Squirrels LLC Verifies Largest Prime Number Ever Discovered

Squirrels built a supercomputer in 2015 to help find the largest and rarest prime numbers ever discovered. We're excited to announce today the discovery and verification of a prime number that's over 23 million digits long! 

The newly discovered prime number is 277,232,917-1. It's calculated by multiplying 77,232,917 twos together and subtracting one. 

This type of prime number, which takes the form 2P-1, is identified as a Mersenne prime. For example, while the smallest traditional prime numbers are 2, 3, 5, 7, etc., the smallest Mersenne primes are 3, 7, 31 and 127 calculated with P values of 2, 3, 5 and 7. 

Squirrels' supercomputer contributes computing power to the Great Internet Mersenne Prime Search (GIMPS). This search is a coordinated global effort that combines the power of thousands of computers to find the largest prime numbers ever discovered.

Squirrels was also one of the groups tasked with verifying the new prime number. This marks the second time the Squirrels supercomputer contributed to a Mersenne prime discovery. It previously helped verify a prime with more than 22 million digits in January 2016.

"We are happy that we are able to contribute not just to the prime search, but to many educational and research projects," Squirrels founder David Stanfill said. "I hope our contribution can help inspire the next generation of curious thinkers."

The next major GIMPS goal is to find the first 100 million-digit prime number. That one comes with a $150,000 award. 

How to get involved 
Anyone with a moderately powerful computer can download the free GIMPS software needed to contribute to the search and potentially earn money for new discoveries.

K-12 educators are bringing the prime number search to the classroom to get students excited about the power of mathematics and teach them about collaborative computing.

Squirrels Developer Tweets 22-Million-Digit Number

Earlier this month, the Squirrels supercomputer verified the largest prime number discovered to date. The prime is unfathomably large at 22,338,618 digits. That’s a number with more than seven million commas!

To showcase just how big the number is, and of course to further programming knowledge, developer Matt Bowen created a Twitter account that is currently tweeting the number.

At a rate of one tweet every 38 seconds, the account will be tweeting for three months. Each tweet contains 100 digits, and in total, the account will send 223,386 tweets. Don’t worry, Bowen isn’t sending the tweets himself. The process is automated.

Squirrels Supercomputer Verifies Largest Prime Number Ever Discovered

We’re excited to announce that one of our workplace hobbies recently contributed to a monumental discovery in mathematics.

Members of our team began building a supercomputer during summer 2015 as part of our 10% program that allows employees to use 10% of every week to work on projects that help them develop professionally. The supercomputer they built is 2400 times faster than today’s average consumer system, and it’s unofficially ranked as the 182nd most powerful system in the world.

Supercomputers can be used for a number of things, but the team joined their newly created system in a coordinated global effort to find the largest prime number ever discovered—GIMPS.

Big task, right? Months of research, infrastructure enhancements and computing paid off this month when a prime number consisting of 22,338,618 digits was found. That’s a number with more than seven million commas in it. The discovery came after 31 days of non-stop computing on a University of Central Missouri computer volunteered by Dr. Curtis Cooper, a professor at the university.

After Dr. Cooper’s discovery, our supercomputer went on a 55-hour sprint to verify the largest prime number he had discovered. The number is much too large to write out, but it is mathematically represented as 274,207,281-1. Written out, the number would stretch for more than 68 miles. The discovery is included in a rare class of primes known as Mersenne primes and is the first of its kind discovered since 2013. This number is one of only 49 Mersenne primes discovered in more than 500 years.

Squirrels SupercomputerOn a normal consumer computer, the verification would have taken months, but the Squirrels system cut this time to just over two days. The risk of an error in the initial discovery is around 2 in 100, but the verification done by Squirrels on different hardware than Dr. Cooper creates an impossibly small margin of error.

The search for primes is never-ending. There will always be greater and greater primes discovered as hardware and software capabilities continue to improve. However, the technology that is developed in the search for primes can have a huge impact elsewhere, such as protein and enzyme analysis in diseases and cancers.

Our supercomputer project is central to Squirrels’ goal in education to excite students and drive them toward interests in math and science. We plan to contribute to other high-profile research projects and not just continue research with prime numbers.

Other projects may include protein folding analysis to help find cures for diseases, deep learning algorithms for rapidly identifying cancerous cells in medical images and extremely detailed physics and chemical simulations to identify potential improvements in battery and other technologies.
