[obm-l] Descoberto o 43 Primo de mersenne
On December 15, 2005, Dr. Curtis Cooper and Dr. Steven
Boone,
professors at Central Missouri State University,
discovered the 43rd
Mersenne Prime, 230,402,457-1. The CMSU team is the
most prolific
contributor to the GIMPS project. The discovery is the
largest known
prime number.
The new prime is 9,152,052 digits long. This means the
Electronic
Frontier Foundation $100,000 award for the discovery
of the first 10
million digit prime is still up for grabs! The new
prime was
independently verified in 5 days by Tony Reix of Bull
S.A. in
Grenoble, France using 16 Itanium2 1.5 GHz CPUs of a
Bull NovaScale
6160 HPC at Bull Grenoble Research Center, running the
Glucas program
by Guillermo Ballester Valor of Granada, Spain.
Dr. Cooper joined GIMPS over 7 years ago with
colleague Dr. Vince
Edmondson. Edmondson was instrumental in the
campus-wide effort until
he passed away in 2003. Cooper, Boone, and CMSU truly
earned this
discovery, diligently coordinating over 700 PCs!
However, Dr. Cooper and Dr. Boone could not have made
this discovery
alone. In recognition of contributions made by tens of
thousands GIMPS
volunteers, credit for this new discovery goes to
"Cooper, Boone,
Woltman, Kurowski, et al". The discovery is the ninth
record prime for
the GIMPS project. Join now and you could find the
next
record-breaking prime! You could even win some cash.
Perfectly Scientific, Dr. Crandall's company which
developed the FFT
algorithm used by GIMPS, will make a poster you can
order containing
the entire 9.1 million digit number. It is kind of
pricey because
accurately printing an over-sized poster in 1-point
font is not easy!
This makes a cool present for the serious math nut in
your family.
