I think the problem is not volunteers: if a project has continous work and admins partecipate to forums, there is a lot of volunteers in the world.

I think so too. I usually have a problem finding projects with enough work, or servers reliable enough to send it out. And it should be good science, not make-work, or I won't bother.
In general, the harder the project (more memory, etc.) the more I like it.

They somehow managed to overlook nanoHUB, which seems to be a similar operation, and was in operation a few months earlier.
https://boinc.nanohub.org/nanoHUB_at_home/

They also are a clearinghouse in effect, drawing on work from a wide range of areas and researchers, though in the nano technology area.
(But everything is nano these days apparently).

They also require VirtualBox, have short run times and high write rates, and require a lot of memory while we are on the subject.

Apparently Universe is a DNS problem. Google DNS won't resolve it, but going to "148.81.25.80" does work.

World Community Grid has been down since about 09:00 UTC. I have many uploads stuck on several machines.
It seems to be unplanned.

EDIT: Now they are going again.

For the chemists, the ambition of this project is to radically change the approach using artificial intelligence and data mining methods in order to more effectively explore the immense combinatorial space of the molecular space.
From what little I know about AI, it could be well suited to distributed computing. We can do the training calculations in small batches on our machines, and they can use the results on their machines (either CPU or GPU) for the final calculations. I don't have any idea if their science is any good, but the only way to find out is to try it.

That card is probably several years old by now. I use mine 24/7, and they usually die in 3 years or so. Try another card.

It’s DNS that Russia has been setting its sights on. At the beginning of April, the country was supposed to test a new method of isolating the entire country’s internet traffic so that citizen internet traffic would only stay within the country’s geographical boundaries instead of bouncing around the world. The plan – which was met with skepticism from much of the engineering community, if not dismissed outright – was to create a Russia-only copy of the DNS servers (the internet’s address book, currently headquartered in California) so that citizens’ traffic would be exclusively directed to Russian sites, or Russian versions of external sites. It would send Russian internet users to Yandex if they typed in Google, or the social network VK instead of Facebook.

This might also explain why sites like USPEX@Home and Acoustics@home are down, or at least unreachable.

True enough. The research may be legitimate. But it may have hit on raw nerves in other parts of the government to disclose the technique and data.

13) Message boards : Projects : Question regarding resource and project management (Message 91390)
Posted 5 May 2019 by Jim1348
Post:
Any hints or suggestion are beyond appreciated.

One problem is that the BOINC scheduler takes forever (almost a month) to adjust the number of work units to the resource shares you set.
A way of speeding it up is to modify your cc_config.xml file (in the BOINC Data directory) to include:

<cc_config>
  <options>	
  	<rec_half_life_days>1.000000</rec_half_life_days>
  </options>
</cc_config>

It should straighten itself out in a couple of days then.
But the BOINC scheduler does what it wants, so don't be too concerned.

Post:
I am not sure what the question is, but I know what the answer is. Create a "User" installable BOINC that runs in the Home directory. Apparently that raises some security concerns. By whom? Not I. I am a home user behind a firewall and would get rid of a lot of the Linux restrictions if I could (I run Ubuntu 16.04/18.04). If they ever want to make it user friendly (not the issue here I know), they will do a UAC like Microsoft, but that appears beyond them.

The number of people running BOINC on secure corporate, government or military systems is probably vanishingly small. I think you would gain far more users by making it easy to use than satisfying some hypothetical security concerns.

By the way, I have learned how to grant all the necessary permissions, and use the Locutus of Borg repository to get the latest version. As for the Manager in Linux, I don't use it, since I have never found anything useful it can do. I use BoincTasks remotely over the LAN, if that helps to answer your original question. So I can live with anything you do with the Linux version, but don't know why I have to.
15) Message boards : Projects : Any projects needing huge memory? (Message 90822)
Posted 28 Mar 2019 by Jim1348
Post:
That is a bit of overkill for anything. The problem is that you don't have so many cores as with the newer CPUs, and so can't use so much memory. But Climate Prediction Network (CPDN) could be your best bet. It is mainly for Windows at this point, and has a somewhat high write-rate. I would use the DRAM to create a ramdisk, or create a large write cache, with all that memory. Plan on at least 1 GB per work unit.

Also, Rosetta has work units that can consume 1 GB in working memory, and sometimes 1.5 GB. The write-rate isn't so much though. It works about as well on Windows as on Linux.

The new nanoHub has work units of varying size, and some of them have very high write-rates so they really should be put on a ramdisk to protect the SSD. Also, it requires VirtualBox, preferably 5.1.38 at this point rather than a newer version for best compatibility. But the work units can use 2 GB each, or maybe more. They are still in startup, and no so much work is available yet, but there could be a lot later.

Also new is BOINC@TACC, which is another VirtualBox project that may use a lot of memory (6 GB per work unit in one report), but there are not that many work units yet either. Good luck.

Interesting, presumably CPDN and others could potentially use this to send test units only to certain trusted computers, e.g. those who are part of the testing programme currently hosted seperately when the testing site is down?

They need it even more for their regular work units that crash when suspended. They could be sent only to the machines that run 24/7, for example. Those machines could be determined by how reliably they return results, or by their own self-selection. I am surprised that it hasn't been implemented by now, given the problems they have.

They have magically come back up, at least the website. I don't know about the data.
I gave up on them a couple of weeks ago, with no info on the daily outages. You never know when they will go down for good, or what the problem is, or if they are even working on it.

Post:
I would think that a continued superficial "panic" mode would be valid until the scheduler started compensating for "overworked" and the scheduler adjusted accordingly in an attempt to balance the work-load based on resource allocation.

Do you think it would tend to work itself out after some time?

I don't recall that the BOINC scheduler ever did figure that out. The BOINC scheduler also does not compensate for limiting the number of cores with an app_config.xml file for example, at least initially. It will continue to give estimates based on the assumption that you are using all the cores, though I think once you reach the buffer size limit it will prevent downloads beyond that. You need to keep an eye on it if you do anything out of the ordinary.

Posted 23 Feb 2019 by Jim1348
Post:
I normally use "fraction done exact", but occasionally it can cause problems. That is, some projects do not show much if any increase in "Progress %" for several minutes. For example, they can hang at 10% for an hour and then jump to 50% or whatever. In that case, the estimated time to complete will be too long if "fraction done exact" is used. Then, the work unit will be forced to run in panic mode, and take precedence over other projects. There may be other problems with it, but that is the one I remember. Otherwise, it works OK, if the progress value is relatively accurate.
