[Climateprediction.net] Unscheduled downtime

Apologies for our unscheduled downtime. This was due to a critical flaw recently discovered in the linux kernel related to networking (see: https://ubuntu.com/security/CVE-2026-98432). If exploited a remote attacker could execute commands on the server. The decision was made at short notice to take our servers off-line.

Unfortunately, it took more than a week for Ubuntu to publish a fix. Although the exploit is difficult to achieve, in these days of AI enabled tools it was too much of a risk to the University systems to leave us online. The downtime was not related to the recent PHP vulnerability which was fixed before the kernel issue was announced.

We will get back to issuing work as soon as possible.

Other users running linux systems might want to make sure their kernels are up to date with patches.

[NFS@home] New Mac sievers

We’ve also rolled out new Mac versions of the 14e, 15e and 16e lattice sievers, built from the current lasieve5 code as a single universal binary. They run natively on Apple Silicon, where they’re about 1.5–1.7 times faster than under Rosetta. To get the native speed, make sure you’re running a current BOINC client. An older Intel-only client will still run the Intel version under Rosetta. The new apps need macOS 10.13 or later on Intel Macs, and macOS 11 or later on Apple Silicon.

[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!

Server outage
The server that hosts the BOINC web site, Science United, and BOINC Central, was offline from 3 Sept until today. There was a maintenance issue that arose suddenly, and took much longer than we anticipated. We apologize for the inconvenience. If something like this happens again we'll try to find a substitute server to keep everyone informed.
