Work has progressed nicely on the GPU sieving apps based on cuda-sieve. Linux and Windows apps are now available for NVIDIA GPUs, with support extended to Maxwell (such as the GTX 970) and newer GPUs with at least 4 GB of GPU memory. For AMD, the code has been ported using HIP, and a Windows app is now available supporting all RDNA-based GPUs (Radeon RX 5000 series and newer) with at least 4 GB of GPU memory. If you have a supported GPU, give it a try!
A new GPU lattice sieve for NFS, cuda-sieve, was recently released. A new app has been added to NFS@Home to test this. Currently, it's only available for nVidia Ampere or higher GPUs running x86_64 Linux. Once the code stabilizes, additional platforms will be added.
NFS@Home again set a new Cunningham project record for the largest penultimate prime factor. 3,709+ factors into 159-digit and 168-digit prime factors, beating the 155-digit record set in April. Congratulations again to all of the project volunteers!
Another year, another BOINC Pentathlon. Once again, welcome back! NFS@Home has been chosen for the Sprint discipline starting May 16 at midnight UTC. Good luck to all! (Including the server!)
The recently completed factorization of 12,311- into 155-digit and 181-digit prime factors set a new Cunningham project record for the largest penultimate prime factor. Congratulations to all of the project volunteers!
The server upgrade is complete. Thanks for your patience during the few hours of downtime.
The NFS@Home server will be upgraded shortly. During this process, the project may be intermittently offline. An announcement will be posted once the upgrades are complete. We apologize for the inconvenience.
Thanks to all the BOINC Pentathlon participants who once again devoted their time and computing power to NFS@Home. The project server was struggling to keep up with you at times, but overall it was a success. And thanks again to SETI.Germany for putting this together again. Until next time!
Welcome back BOINC Pentathlon participants. NFS@Home has again been chosen this year for the Javelin Throw discipline starting May 9 at midnight UTC. Good luck to all!
Thank you to all the BOINC Pentathlon participants who devoted their time and computing power to NFS@Home, and to SETI.Germany for organizing this event. We look forward to next time!
Welcome BOINC Pentathlon participants. NFS@Home has been chosen for the Javelin Throw discipline starting May 10 at midnight UTC.
The NFS@Home server was unexpectedly caught up in a campus network reorganization. That knocked us offline for a bit over a day. There may be brief outages over the next few days as we get everything settled again, but we are mostly back up with a new IP address. We apologize for the inconvenience. Edit: The site came back up in the US on Friday afternoon PST, but because of a misconfigured firewall it wasn't available worldwide until Saturday afternoon. Again, we apologize for the issues.
The NFS@Home project will be offline much of the day on Saturday, May 27, due to campus IT maintenance and testing. All access should be restored by 8pm PDT. Greg Childers
NFS@Home has found a new record penultimate prime factor! 7,889M, which is a portion of the number 7^889+1, splits into 151-digit and 160-digit prime factors. This 151-digit prime factor beats the old record, a 147-digit prime factor of 12^293+1. Congrats to all contributors who helped set this new Cunningham project record!
The Hogmanay Hootenanny 2022 challenge begins shortly on Dec. 31 at 12:00 UTC. Welcome to all participants!
I have modified NFS@Home to use SSL. As a result, the project URL has changed from http://escatter11.fullerton.edu/nfs to https://escatter11.fullerton.edu/nfs. If you see problems as a result of this change, you may need to remove then reattach the project. Old http links will continue to work.
Two new apps have been launched, lasievee_small and lasievef_small. As the numbers we factor become larger, the lasieved app has largely become inadequate while the lasievee app queue has grown very long. In an attempt to compensate, job memory use and runtime has crept upward to stretch the capability of the apps. To alleviate these issues, these new apps will provide additional flexibility to choose the app most appropriate to the size of the number being factored while keeping memory use…
Welcome BOINC Pentathlon participants. Note that if you haven't participated in NFS@Home recently and are having trouble queuing work, then complete a few workunits and send them back. The server doesn't send much work to machines that haven't returned any recently.
Due to an unexpected campus-wide power outage, the project was offline for several hours. Power has been restored, and the project is returning to normal. Thanks for your patience.
As supported by the current BOINC server software, I have enabled the option to delete your NFS@Home account if you wish. Please note that if you choose to do so, it is permanent. Deleted accounts are removed from the database and cannot be recovered.
It's been quite a while since the last news post, but work has been continuing. On the status pages you can follow the many completed factorizations. Also, I yesterday I updated the BOINC server code to the latest version.
