This any help?

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.

Several of these tasks that are running for twice my set computation time and not checkpointing to boot. I hope I get some sort of credit for these.

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.

Added SiDock as a backup.

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

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.

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.

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....

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.

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.

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

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!
