Thanks. I suspected something like that might be the case. It will be interesting to see how the project copes with it given that there are an awful lot of set and forget crunchers out there and the set and forget crowd are unlikely to have 5GB+/core on their boxen.

Post:
Last night I ran a task for a project testing programme where memory usage topped 5GB at times. I imagine that if these tasks make it to the main site, lots of users who like myself, only have the currently recommended 2GB/core will either find tasks slowing down a lot or not be able to use all cores. Would increasing the size of the swap partition (these tasks are Linux only at least for the present) to give enough headroom be enough or are they still likely to run into problems? Swap is on an SSD on this machine.

Glory.
New battery seems to last about 25% longer which is not bad for an extra 20mAh 2440 as opposed to 2420 and if the old one holds it's charge when not in phone I can carry that around and swap when out and no access to charger. A bit smaller to carry than the battery that gives me three and a bit charges when full.

Don't they teach their drivers how to ring doorbells? I would even have heard it down the garden if they had.


Tomorrow morning will put sign on door asking them to ring doorbell when I get up.

I presume when the tracking link says, "In transit" it is referring to the van it is in?

Second attempted delivery failed. Ignored my having given a place to leave battery and ticked the signature not needed box. Wasn't in on this occasion as 70 miles away due to ill Father in Law who passed away aged 93 yesterday morning and didn't get enough time to change it before leaving. Trying again tomorrow morning!

As an aside, a week ago when we knew he was dying, he informed us that he was going for a career change and was going to train as a helicopter pilot!
7) Message boards : BOINC Manager : Limit Work By CPU Core Temperature (Message 91109)
Posted 5 days ago by Profile Dave
Post:
How about a configuration option to dial down the computation speed or amount of CPU usage if the CPU reaches a preset temperature; for example, 60C.


I guess an alternative would be to use the PC's software to throttle the CPU to keep the temperature within desired limits?

With my laptop, in warmer weather I just use fewer cores and if this were to be looked at (and I doubt if this is likely to be a priority though the android version will stop computing if temps get too high) shutting down one or possibly more cores would by my preferred way of doing it.

Edit: Started writing my response before being called away so didn't notice your answer Richard.

My situation, Xubuntu 19.04 having just upgraded. When tasks for my main project are available natively under Linux I run them. However, when not available I run Windows tasks using WINE.

If the choice to stop the client using the manager goes, I then will start using sudo kill xxxx where xxxx is the process number of the client. Not a great hardship but I would much refer to do this via the manager.

And now a grumble!
New battery ordered for Fairphone2 as old one not holding charge as well as it once did. Card through door alleging attempted delivery at 09:15. I was in Kitchen at the time. Don't they teach their drivers how to ring doorbells? I would even have heard it down the garden if they had.

Upgrade to Dingo went according to plan and seemed quicker than previous version upgrades. Will play with it for about a week before doing second machine.

Ubuntu 18.10 (soon will change to 19.04) I would class myself as an intermediate user i.e. I can track down the different 32bit libs needed for some BOINC apps and install them without having to look for a post on the subject and copy and paste the commands.

While I could live with losing those commands from the manager I would much prefer to keep them. Under the old system, before the only ways to get an up to date BOINC for Linux were via the package manager and to roll your own (something I have yet to succeed in doing.) I liked being able to download and unpack the files where I chose and run it from there.

Currently I am running the windows version under WINE as no tasks available from CPDN for Linux at the moment.

I would try a reset project or detach and re-attach to wcg. - doesn't hel with understanding why but should I think resolve the problem.

Try running sudo /etc/init.d/boinc-client start in a terminal. If the client has not been started automagically, that should start it.
and see if that resolves it. also check that under option>Other "Run the client" is checked.

Another thing you could do is run Top in a terminal to see if the client is running.

Currently running is the Quake Catcher, Amicable numbers, Seti@home, and Milkyway@home.


I may be wrong but I thought QCN uses virtually nothing just monitoring a sensor so you should have the best part of a core free so at the moment, your system shouldn't be that stressed?

Here is the Linpack performance of the latest Pi 3+ in comparison to older versions


About a fifth of the performance of my machines which are still slow by today's standards. ARM need to bring out something a lot faster before there would be any point in the projects which have longer tasks developing for it. Those with short tasks are another matter as there are so many android and other arm processors out there they could make a significant contribution.

I hate to think how long a Raspberri Pi would have taken for that task - certainly longer than the project researchers are willing to wait.


The CPDN tasks running on my laptop are going to be between 10 and about 45 days total computing time. While not the fastest machine on the block by quite a ways, it is still a lot faster than a Raspberry Pi. And I think if I didn't know the estimates were way out running under WINE I would have given up on seeing them on it never mind with a Pi. (One that I estimate based on time and work done will take 16 to 17 days has an estimate of 188 days! I shudder to think what that would be on a Pi?

However, My laptop running 7.14.2 under WINE with Ubuntu 18.10 just shut down for no apparent reason. Only running using 2 cores for BOINC and nothing else running so overheating seems less likely.
