Re: [SiDock@home] Second target (corona_PLpro_v1)

Target corona_PLpro_v1 is now at ≈91 %. Maybe the current ≈9,600 tasks in progress make up the missing 9 %. ( https://www.sidock.si/sidock/server_status.php ) We will soon finish the second target SARS-CoV-2 PL -Pro as well. I'm not sure what this means, but for now I interpret this as "We will soon...

Re: Low power video card

If they make its TBP ≈20 W, not 30 W like reported, then it could be a 1:1 GT 710 replacement, which they then could phase out. (Did the Kepler based GT 710 already replace a prior Fermi based eponymous GT 710? — Edit, nope, the Fermi based one was called GT 705.)

Re: Linux: How to disable mitigations for CPU vulnerabilities

While I never profiled its effects, I have mitigations off on all of my DC-dedicated computers.
It was a small nuisance to figure out how to set the GRUB config accordingly in Mint.
In OpenSuse, there is a dialogue for this in their central system management GUI.

From what I remember, the now long submerged Acoustics@home had better performance under Windows than under Linux. They linked the Windows build against a heavily optimized non-free math library, while the Linux build had to make do with a version which lacked all the optimizations.

Re: Low power video card

Baseboard Management Controllers (BMCs) are not only low-power video cards, they also allow for remote management, even down to remote access to the BIOS. Downside: They don't come as add-in boards; you need to buy a mainboard with them. Related news: https://www.anandtech.com/show/16349/the-asrock-...

Re: Running Linux VM under Windows, performance hit?

For performance comparisons, the fact that NumberFields is using fixed credits currently is nice. But the run time variations are huge. On a high-core-count CPU, half a day of testing time is certainly appropriate, but more than that may be necessary on low-core-count CPUs. For quicker testing with ...

Re: Low power video card

1080Ti is generally at circa 8 W when idle (in Linux, measured by the board sensor). Or maybe more like 9 or 10 W for a GPU which displays an idle Cinnamon desktop, and 7 W for an unused secondary GPU.

If I remember correctly, 1070 and 1080 had the same idle consumption.

How well are Windows + VirtualBox balancing the load on a 64-thread SMT machine? If you have the time, try a similar test while SMT is disabled in the BIOS.
