Project Update

[Dataman]

Noticed very few of us are active at NFS and I had never run it so I put some CPU's there. Better than average credit and it is not a CPU Hog. Seems to run ok with BU.


EDIT: Received 3 badges on the first day.

New badges. 

I see there's now - NFS@home (15e small) & NFS@home (16e small)



Edit - Massive memory hogs!  The 15e's are around 420Mb/wu and the 16e's around 600Mb/wu.

NFS put out this message but the project was down when I went to look.

[NFS@home] And we're back!

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.

Thanks for the update Dingo.

[NFS@home] CUDA-based GPU sieving test
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 has a snazzy new web site.  Not sure if this is the new BOINC one or a NFS mod at this stage.

[NFS@home] GPU sieving
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!

[NFS@home] New Windows sievers (and a quick fix for Windows 7 / 8.1)
We've rolled out new 64-bit Windows versions of the 14e, 15e and 16e lattice sievers. They're built from the current lasieve5 code, so Windows machines run better on newer, larger jobs that the old Windows apps couldn't handle. They're also quicker. If your CPU supports AVX-512, the app uses it automatically, and on our test machine that was about 1.4–1.6 times faster.

The few of you who still use Windows 7 or 8.1 may need one small update from Microsoft. The new apps need Microsoft's "Universal C Runtime". Most machines already have it, but some don't. If yours doesn't, NFS@Home tasks will fail right away with an error like:

exit code -1073741515 (0xc0000135)

Check first: if the file C:\Windows\System32\ucrtbase.dll exists, you already have it. If it's missing, install the update one of these ways:

Windows Update (easiest). Open Windows Update and install the recommended updates. The one you're after is called "Update for Universal C Runtime in Windows".

Direct download:
Windows 7 SP1, 64-bit:
https://www.microsoft.com/en-us/download/details.aspx?id=51161
Download Windows6.1-KB3118401-x64.msu and run it. Windows 7 needs Service Pack 1 installed first.

Windows 8.1, 64-bit: search the Microsoft Update Catalog:
https://www.catalog.update.microsoft.com/Search.aspx?q=KB3118401
Download "Update for Windows 8.1 for x64-based Systems (KB3118401)". It needs the April 2014 update (KB2919355), which almost all 8.1 machines already have.

Windows 8 (not 8.1): Microsoft no longer offers this update for Windows 8. Please upgrade to 8.1 (it's free).

Restart if Windows asks you to. New tasks should then run normally. Any tasks that already failed will be sent to other computers, so no work is lost.

Thanks for participating, and let us know on the forums if you run into anything!
