10,770M factors

NFS@home

10,770M has been factored. It is the product of 102-digit and 111-digit prime numbers. This is a new Cunningham project champion for GNFS. Thanks again for stepping up to the plate and helping finish this one before the end of the grant year on Oct. 1!

7,394+ factored

NFS@home

7,394+ has been factored. It is the product of 71-digit and and 126-digit prime numbers. 10,770M is nearly complete, and the sieving of 3,766+ is going well.

BOINC

Upcoming outage

NFS@home

The campus has announced a planned network outage from Friday, August 16, at 7pm to Saturday, August 17, at 7am Pacific Time. The project will be unavailable during this time. We apologize in advance for the inconvenience.

BOINC

3,745+ and 3,706+ factors

NFS@home

Both 3,745+ and 3,706+ have been completed. 3,745+ was the product of 62-digit and 140-digit prime numbers, and 3,706+ was the product of 62-digit and 145-digit prime numbers. These are the new first and second place Cunningham project champions for GNFS.

Unscheduled downtime, August Heat challenges

NFS@home

There was unscheduled downtime today due to a campus-wide power outage. All is now back up and operational. We have upcoming challenges at BOINCStats. Be sure to join in the challenge, boost your team in the stats, and have some fun!

Calling all 64-bit Linux sievers!

NFS@home

To finish the 10M770 in this grant period, the 64-bit Linux 16e v5 sieving speed needs to triple for the next couple of months. If you have a 64-bit linux machine free, please consider contributing to the sieving. If you are contributing using 64-bit linux computers, consider changing their "location" in the host details screen linked from http://escatter11.fullerton.edu/nfs/hosts_user.php to a currently unused one, then setting that location to get only lasieve5f workunits in your NFS@Home…

2,1049+ factors

NFS@home

2,1049+, our second largest factorization, is now complete. It was the product of 104-digit and 115-digit prime numbers. Likewise, L1803 and L1809 are also complete. 3,745+ is postprocessing now, and the sieving of 3,706+ is going well.

New Windows x64 apps deployed

NFS@home

Building on the work of Dan_Ee, I have compiled and deployed new Windows x64 apps. These are 50% to 100% faster than the 32-bit apps depending on your processor. Please let me know if you encounter problems.

BOINC

kilobit postprocessing underway, factorizations completed

NFS@home

The postprocessing of 2,1049+, our fourth kilobit factorization, is now underway and is expected to take about 4 weeks. The factorizations of F1229 and L1797 have been completed. We will now be working on successively harder GNFS factorizations, and the sieving of our first, 3,745+, is going well.

Upcoming BOINC challenges and completed factorizations

NFS@home

Starting at the stroke of midnight (UTC) on April 1, NFS@Home will be hosting the April Showers challenge at BOINCstats. If you haven't done so already, be sure to encourage your team to participate! In other news, the factorizations of F1821 and F1839 have been completed. Thanks again for all of your contributions!

2,1037- factored

NFS@home

2,1037- has been factored into three factors. It is the product of 67-digit, 86-digit, and 137-digit prime numbers. The sieving of 2,1049+ is going well. Thanks again to all who make this project a success!

11,301- and 3617523089023,19- factored, 2,1037- postprocessing

NFS@home

11,301- and 3617523089023,19- have each been factored into their prime cofactors, and have been reported to the Cunningham and OddPerfect projects respectively. Thanks to your participation, the December to Remember challenge certainly was one to remember! The surge in computing power allowed us to complete the sieving of 2,1037- before the end of 2012. It is now in postprocessing on the Trestles cluster at the San Diego Supercomputing Center and should finish in a few weeks. Thanks again for…

One billion credits!

NFS@home

The NFS@Home project is on track to surpass 1,000,000,000 credits awarded today! As a CPU-only project, this is a significant milestone for us. Thanks for all of your hard work and dedication to the project!

BOINC

11,301+ factored

NFS@home

11,301+ has been factored into 104-digit and 107-digit prime numbers. The challenge is going very well with nearly 8.5 teraflops of computing power devoted to NFS sieving. The server is a little slow, but it's keeping up with the work. If this rate continues the sieving of 2,1037- will be complete before the end of this year!

We'll be back in a couple of hours...

NFS@home

We had a hard drive failure. No data was lost, the drive has been replaced, and I'm taking the project down for a couple of hours to allow the RAID array to rebuild more quickly. We'll be back shortly...

BOINC

3,637+ factored

NFS@home

3,637+ has been factored into 63-digit, 66-digit, and 109-digit prime numbers. The postprocessing for 2,1019- is going well and should finish before this weekend.
