Thanks, I may give this a try.
I wasn't sure how relevant this was since Linux is now able to be run via Chrome OS, but I will try it again and see where I get with the commands given.

Hello
Just recently grabbed a Lenovo Chromebook Duet. Really nice for the price.
Attempted to get Boinc running on it via the Linux development options, but unfortunately having no go of it. Not sure what the specific steps entail. Boinc doesn't seem to be starting when I use /etc/init.d/boinc-client start. Similar to Boincmgr.
Just to make sure, I attempted changing settings in the normal boinc directory (/var/lib/boinc-client) to try and get remote access doesn't seem to function either - not sure if the IP address of the chromebook is being blocked via external access or not.
Has anyone gotten this to work, or should I just resort to the boinc client on the play store?
Any help appreciated.

Thannk you, this is super helpful and I will do so.
I don't think some of these tasks are going to complete in time for the deadline without checkpointing. I'm going to try and keep the client running but they're also using pretty excessive amounts of ram.
I thought the quorum for each task (number of machines to complete) needed to be 1? Or do you mean others, apart from myself, also get this task, in case I don't complete it first?

The usual quorum used to be two, but has often been 1 lately. A quorum of 1 is adequate only for tasks for which some quick method of checking the output of the task is available. If the quorum is 2, the first two sets of task output files returned must agree enough before they are considered validated. If they don't agree enough, one more task is sent out to determine which of the first two tasks is correct enough to be validated. The purpose of the quorum is to check whether the task or tasks returned correct outputs, even if the task did not detect an error. Sometimes, a workunit with an error in its input files will give some credit if other tasks for that same workunit agree on detecting the error.

Usually, the first group of tasks sent out has as many tasks as the quorum, so if the quorum is greater than one, at least one other person will also get a task for that workunit. For each task that goes past its deadline, one more task for that workunit will be sent out. You have a head start on any task sent due to another task reaching its deadline, and therefore some chance of still returning it in time.

If the tasks are using excessive amounts of RAM, you may need to tell BOINC to reduce the number of tasks it is allowed to run at the same time, so that the reduced number will fit in the amount of RAM you have available.

I normally keep my computer running and doing BOINC work day and night, so it can handle tasks that go over 24 hours between checkpoints.

Hi,
I normally do too, on all but one. Of course that was the one that had these issues. The tasks ended up erroring out though they for some reason displayed a vast amount of credit, over 400.
Thanks for the explanation. That clears things up.

[snip]

Rosetta@Home tasks have sections known as decoys. The decision on whether to end the task normally occurs only at the end of a decoy.

Your very long run time looks like you got at least one task with a very long time per decoy.

I have no information on whether checkpoints are also written only at the ends of decoys. However, if so, this is probably why you also had the long time with no checkpoints.

You might want to read the log file from that task to check whether it completed only one decoy.

Also check if you can read the log files from any other tasks for that workunit. If all of them were that slow, expect to get some credit as long as you either returned it by the deadline, or returned it before the quorum was met.

Thannk you, this is super helpful and I will do so.

Good!

Any particular reason to add TN grid specifically?

- consistent and stable queue of wus
- optimized app (sse3/avx)
- admins on forum
- i'm italian and it's an italian project :-P

Well, added this project and set Sidock to no new tasks, for the time being.
Much shorter runtimes for when this project gets new work, and I can actually put that avx and FMA to use instead of just wondering if it is.

Thank you for that info.
I'll just let Boinc and the project worry about it. I just wanted to make sure nothing was amiss.
Here's hoping more work appears.

Hello,
I just noticed this, and not sure if this will make a difference in credit received by my machines on this project. The wetstone value seems incredibly high.
I just ran a benchmark via Boinc. Intel xeon e5-2680v1.
8/24/2021 1:01:14 AM | | Running CPU benchmarks
8/24/2021 1:01:45 AM | | Benchmark results:

8/24/2021 1:01:45 AM | | 56045 integer MIPS (Dhrystone) per CPU
Anyone else experiencing this? Should I just ignore it?
thanks!

One upside to these - at least from what I can see - they take a lot less time to run, maybe an hour.
My two larger processors - 2 Ryzen 7-3700's. Sidock seems to do okay with them - nice and small requirements - but sometimes I run into scheduling issues. Even my 4770 has problems and the scheduler can't keep up at times.
I should check out tn grid again. I gave up pretty hard on LHC at home which is a shame as the science was very neat, but ran into constant issues, I do not have time to fiddle with things these days, given it is summer and the beach calls.
These Ryzen's are doing so much work versus the e5-2680 I had going in here and my air conditioner is kicking in so much less. Add to that - the incredible amount of hot temperatures and it's only June, best purchase I have made.
How do the 5000 series from AMD (Zen 3) do on this project? I couldn't find one at a decent price, the 5600 was more expensive than this 3700.
I might snatch up yet another 3000 series - maybe a 3600.

How much memory does each WU consume with these new python WUs?

You won't believe it. They use 8 GB per work unit. Maybe they have reduced that, but VBox will be the easy part.

8 GB!
Good thing 2 of my Ryzen's have 64, but ...still!
That's just a little excessive.
Hopefully that comes way down or gets optimized before these go into main production...

Hopefully they don't switch exclusively to vbox - or give users the ability to choose workunit types. There are doubtlessly countless machines that do not have virtual box installed and likely will not do so as they simply sit and crunch with users not checking the forums.

How much memory does each WU consume with these new python WUs? Do they finally use SSE/Avx? I don't think I have gotten one yet.
thanks

I'd suggest to not suspend it at all and see if some issues occur....if a non-BOINC application needs 100% of the CPU, it will get it.


I might try the exclusion thing that Grant suggested. The reason that I turned off BOINC was that on this laptop, which is optimized for weight and not performance, the latency of the handoff from BOINC to Zoom was a problem, not that it made the handoff at all.

This is what I use, especially for meetings involving video and / or screen share. Just make sure you have enough memory to keep tasks suspended indefinitely without thrashing the swap. Not that Zoom uses a lot.

So a problem I've had lately on Just a few of my Linux machines. Boinc doesn't actually start on system startup. I have to do systemctl restart boinc-client.
This then resulted in MLC at home giving me tons of mount errors telling me it was read only, yet Roseta works just fine. I followed the same procedure - sudo apt-get install boinc virtualbox. This is after adding the unofficial repo - ppa:costamagnagianfranco/boinc.
I have no idea how this has happened or what I did wrong here but attempting to reinstall did no good. With each restart Boinc must be manually restarted. I'm still very much new to Linux and don't really want to go through an entire OS install. I've tried chmod to the boinc directory, that did no good.
Anyone have any ideas?

I might replace the i7-920 with one. Currently the dual Xeon 5520 seems to be holding its own even at a lower clock speed.
Pah! I've got four X5650 CPUs in two motherboards. Not the fastest things ever made, but they do 48 tasks at once between them. They're not even in cases, they're loose on a bookshelf, which alarmed someone once who told me I was being very unsociable by letting all the EM interference out. Maybe that's why my neighbour has installed a weird device on his shed to boost a mobile or Wifi signal :-)

RAC seems to be quicker about increasing since I performed benchmarks on (I think)? everything. Maybe that's just me.
It should do it itself when you install Boinc, change hardware, and also periodically, but I've heard that sometimes it forgets. Boinc is so buggy. Why do programmers expect the users to find their mistakes nowadays? Don't they do testing anymore? And why does this forum keep removing my double spacing between sentences?!

One day I'll have tons of money to burn and can grab me up 2 threadripper 5950x.
Don't, the 5950X costs 2.5 times more than the 3900XT, and only goes 1.38 times faster. Always best to buy about the 5th fastest CPU. Let the millionaires throw money at the new ones to pay the development cost.

The basement of my house is currently a nice warm area, warmer than upstairs and it's winter.
Mine are in the garage (5 soon to be 6). Unfortunately the garage is not (yet) connected to the house, so I'm heating the house with electricity and throwing Boinc heat out of the window of the garage. I must get the tarrif "changed" on that meter....

I have a 3700x and might get a 5600 when they're actually available here. But we'll ultimately see.
I haven't seen more than 360 credits per task at Roseta so I wonder if there is a bottleneck in how much a CPU actually gets done due to no AVX/SSE? i5-3570 and Ryzen 3700 get about the same credits per task.
Not that credits are the entire story. I'm just glad the science is getting done.

Hi
My benchmarks are all odd with Linux - Ubuntu 1804.
I'm far too lazy to actually try and upgrade everything to 20.04 with such a small issue unless there is some super amazing things that it will do for me.
I need to retire a lot of these systems - my poor i7-920 and Xeon w3520. Trying to run them into the ground.


Actually you need to get another Xeon w3520 cpu and put them both in a dual cpu board and bang out twice as many tasks as you are right now.

I might replace the i7-920 with one. Currently the dual Xeon 5520 seems to be holding its own even at a lower clock speed.

That’s at least in part because the i7 hasn’t sent Rosetta its performance measurements yet.

Ugh. I thought Boinc did this automatically. One more bug.
Thanks for letting me know I'll go ahead and do this now.

Going through my tasks to search for these.
Hopefully these get yanked from the server sooner than later. A lot of my machines can handle around 2 gb per thread. The Ryzen 3700x can handle about 4, as well as a few others.

Left it at the default 8 hours. I'd guess they know best as far as what they want.
From a purely selfish point of view, I prefer ones with a variable time (fixed amount of processing), then I can see them flying through on a faster machine!

I can see that for sure.
It's hard to figure out amount of work done proportionate to each machine on this project since the credits vary so drastically from one type of workunit to the next. How is it my i3-2130 is making more credits on work than an i7-4790 which is averaging about 90 or 100 credits per WU. I guess as long as science is being done that's what matters.
