Trying to decipher their status page is a bit of an art. But I think that the fact that "avg runtime of last 100 results" shows "0.00" means that nobody completes them.
It is a new form of black hole.

No, it takes a certain amount of energy - which is the product of power and time.

I figured someone would catch me on that. But the question is what can BOINC do to control those variables?
I suggest a "laptop mode" that cuts the number of cores to half of the total. That will be more reliable than anything else.

But we don't know how much power reduction can be achieved via BOINC or any other technique. That may argue for trying it, but I don't think it guarantees any success. It takes a certain amount of power to calculate a certain amount of work. Laptops were not designed for DC.

If BOINC can make it better, good for it. But I would not be too surprised if not much more is possible than just adjusting the fan based on the GPU temperature, as is done now. Otherwise, it suggests that both Linux and Microsoft are falling down on the job of running their stuff efficiently. That is possible, but can BOINC improve on it?

I like the ideas about making it easier for scientists to use BOINC. From what I see, there is a shortage of good new projects. In many cases, there are more crunchers than work in interesting areas. If more scientists can access BOINC, we each have a better chance of getting what we consider to be "good" work.

As for fan noise, video playback, etc. that is probably important for some people. But I use dedicated Linux machines that have the right amount of cooling and no contention with other applications, so I would not compromise performance for that. In fact, I would prefer higher CPU (and GPU) utilization where possible. So such techniques to minimize impact on non-BOINC processes should be made optional for those who want them.

I am glad you are thinking about these things. Good luck.

They were sort of thinking about AVX 512 on LHC, but nothing has come of it.
This post refers to CMS, but I have seen it mentioned for SixTrack too.

It is said to be a not very efficient use of chip area, and Intel may not repeat it.

A very interesting one that is not listed on BOINC is TN-Grid, for genetic research.
Note that you need an invitation code, but it is listed on their front page.

They have reliable servers, and lots of work.

>>> i7-9700 (Ubuntu 18.04.3)

Good to see that it is not a Windows specific problem, I know a lot of research establishments use Linux as it is cheaper. Does make me wonder though, if it is showing bizarre behaviour on both systems, what did they test it on before starting this exercise?

It is also not Intel vs. AMD. The same thing happened (after 2 days 11 hours) on my Ryzen 3700x, also on Ubuntu.

Today, the machine with six jobs is back to showing 1.000% complete, the estimated run times have changed one is 3d 16:06 and counting, two of the others show 370+ days, two more 390+ days and the last 422+ days. This machine has now used upwards of 21 days on these jobs. All aborted - 21 days of crunching wasted.

After about 1 1/2 days of progress on my i7-9700 (Ubuntu 18.04.3), the same thing happened to me.
I am out. This thing is not ready for prime time.

Thanks. That is the definitive answer. Yes, it usually is not relevant anyway.

When you detach from a project, is that fact communicated to the server?
I would think that could be useful, but have never seen it mentioned.

Doesn't he mean that a network problem would be common to several of the services?
If it were just a server problem, it should affect only one or a few.

I just tried attaching to https://www.cpdn.org/, and no response.
It is getting late in the UK, so I will try again tomorrow.

I have had various AHCI driver problems over the years using BOINC when combined with other factors. Are you using a disk cache (such as Samsung Rapid Mode cache)? That can trigger problems, though I am using it now reliably. It helps to have the latest version. Also, I have found that various anti-viruses can trigger problems; try a different one, or just use Windows Defender.

And I have found this website useful in choosing the most stable drivers for various motherboard chipsets:
https://www.win-raid.com/t25f23-Which-are-the-quot-best-quot-Intel-AHCI-RAID-drivers.html

In fact, I have found that combining SSDs with rotating disk drives is bad; I now use only SSDs, even as a backup for storage.
And if all else fails, replace your SATA cables. They do go bad.

The goals and methodology look very nice.

I would like to try it out as soon as possible, to check whether it runs better on AMD or Intel (probably Linux better than Windows, but I will check that too). But apparently it used VirtualBox, so there may not be very much difference.

Anyone with som inside info from the project?

No. I gave up and detached. The reporting is only for the credits, which I don't look at anyway. But I think the science results were returned OK.
I wonder about them. They seem to be in slow decline; maybe faster now.
