After that I will probably be turning everything off for a few days while I have a hip replacement!
Dave, best wishes for the op.

I do wonder if once I double my RAM I could get rid of swap altogether?
Probably not a good idea to get rid of the swap file. The OS behaviour would be unpredictable.

I've received a Batch 995 WAH 8.24 retread from July 2023. wah2_nz25_20aa_209105_25_995_012220768.

Should this WU be crunched or abandoned, please?
Thank you.

It would be most helpful if we could identify which anti-virus products are reporting a detection.

That won't ever be identifiable in your server logs: we would probably have to crowd-source it by an appeal here. So: if anyone here has noticed an AV alert relatable to CPDN since the new tasks were released, please post details here.

I don't have any recent experience of a central, industry-wide, reporting point, although I have written and released software installation packages in the past which have triggered similar problems.

Unfortunately the BOINC message board most likely to have searchable records of such events (SETI@home) has been offline all day, although it's back now. I'll put my thinking cap on in the morning.

CPDN with a corporate McAfee anti-virus, 2005 to 2017. No issues to report.
CPDN with M$ anti-virus (Defender) 2017 to 2024. No issues to report.
Recent model/task crashes 2024, Nothing that I could attribute to the M$ anti-virus (Defender).

As requested, five EAS tasks from batches 1002 1003 and 1004 have been aborted. One NZ task from batch 1005 is still ticking along. The CPU fan has gone quiet!

I see the faster machines have started to return results. Still over 2 days till the first of mine finish but it does mean the number of tasks waiting to be sent from these batches is going down a little faster now.
Two more days for the first tasks to complete here. They survived Storm Isha brown-outs yesterday evening. We have planned power outages tomorrow, for connecting the solar panels, battery and a new charger. So fingers crossed that the WAH models behave after 'hibernate'.
Most of the solar work is complete. Unfortunately, waking after 'hibernate' lost three of the five running tasks. The other two tasks should complete before the commissioning.
Two tasks finished succesfully. I've let just one task start and set 'no new tasks' while the contractor cracks on tomorrow with the solar and battery installation and commissioning.

... I can't leave it on and working 24/7.
'Sleep' rather than 'power off' will keep the Windoze system in memory and works OK for me with WAH2 tasks. Additionally, manually control 'Windoze Update' with 'Pause' for as long as it will let you and restart the updates after the tasks have finished. 'Hibernate' should behave similarly, saving to disc, although I have not tested the feature with WAH2 tasks

Hi all. Trying to upload one stubborn zip file, but no success. Is their server down or just overloaded?
From 11 WAH tasks, we had ten upolads waiting yesterday afternoon and five waiting today. Looking in the event log: there are a lot of upload starts and temporary upload failures, interspersed with a few groups of uploads finishing. We have found that it is best to be patient with BOINC and CPDN. Unless told otherwise by those that know better, I'd let BOINC do it's own thing with a stubborn upload.
14) Questions and Answers : Windows : Computation error when BOINC halts (Message 69368)
Posted 19 Jul 2023 by wateroakley
Post:
As for Windows automatic updates - they are an absolute pain, and should be blocked - others have suggested ways of doing this.
I fully agree for experienced CPDN users. However, more than 50 years of computing experience tells me that there are many many users where forcing OS and application updates, especially security updates, is an imperative.

Post:
Is there a setting I need to check or something to keep this from happening?
Pause 'Windows Update' for the maximum amount of time, that stops Windows annoyingly doing an update while CPDN tasks are runniing. 'Resume updates' after the tasks have fnished to keep the OS up to date, and then pause again.

May I ask what yoiu would advise for a UK solar choice?
Annually we use 7,000kWh, with 4,500kWh for home and 2,500kWh for EVs. That's down from 9,500kWh total use in 2017
We went down the local government group purchase route for solar. 20x 400W panels and 10kWh battery. £20K-ish with 8-12 years ROI.
I'm a qualified electrical and electronic engineer, so can close out a lot of the BS. The solar implementation from the LA selected provider did not start well. Luckily, we got our deposit back. Say no more :(
Any advice welcome.

Five tasks downloaded on this WIN 11 PC. Four crashed almost immedlately with the event log complaining about missing output files. The four took took a little while to report and std.err complains about Segment violations. Number 5 task is ticking along nicely. After four hours the task is 2.1 per cent though, giving a run-time estimate of 189 hours or about 8 days.

This is an interesting article I saw today.

The Upper Atmosphere Is Cooling, Prompting New Climate Concerns

A new study reaffirming that global climate change is human-made also found the upper atmosphere is cooling dramatically because of rising CO2 levels. Scientists are worried about the effect this cooling could have on orbiting satellites, the ozone layer, and Earth’s weather.

A very interesting read, Jean-David. I'll have to brush up on my atmospheric layer science (and the relevant maths).

Posted 10 Mar 2023 by wateroakley
Post:
Unless there is a setting I haven't found, the Dreamlabs app only runs when the phone is charging. It can't be using a lot of power as phone doesn't warm up at all unlike if running BOINC with just two cores crunching. (when I run BOINC I stick to just one core because of that. Be interesting to see what speed the dreamlabs app runs on my Linux box though. (Currently downloading ISO.
According to the FAQ, the App only works when plugged-in and powered. We downloaded a Monterey iso yesterday. If I get time over the weekend, will see if I can get the newer mac VM working with VirtualBox.

If anyone's interested, this is another task fail which is different to the turbulence failure mentioned earlier:
https://www.cpdn.org/result.php?resultid=22313995

So this storm got pretty powerful!
It's earlier run of the workunit reported the same results for wind speed at the same step: https://www.cpdn.org/result.php?resultid=22307272
That's very reassuring that the science/physics/programmimg/perturbations give consistent results.
