Thanks Glenn. That makes sense. I had wondered about why the usage was so high. Pleased to say they all finished with no issues my end.

Six downloaded here. (Placeholder for this batch)
I assume this means you have tracked down the problem Glenn?

Just checked, the instructions for Ubuntu in the other thread on this subject still work on Ubuntu 24.04. Nice that no names have changed and I don't need to go searching for it all.

It's probably where the model was restarted and ran over a trickle up timestep again.

Just so long as this doesn't allow gaming of the system for credit purposes!

Edit: Probably not an issue as repeated instances of trying that would probably crash the task.

There are some new OpenIFS BL app batches coming once code development & testing is complete (some time yet).
Yes, I wasn't expecting them to appear on the main site for a while in fact I am pretty certain there is time for those whose motherboards can accommodate it to upgrade their RAM in preparation and still have a fair old wait!

Andy has sent some tasks out for testing. these are peaking at a bit over 9GB/task which is the highest I have seen yet I think.

Won't they all go under 0C? People put wires outside all the time. My mother keeps her mower and extension cords in the garage and it gets to -10C there. They just go a bit stiffer.
Insulation not rated for the lower temperatures will likely get brittle. Norway and Finland often get -40C. When in the forces I saw insulation intended for warmer climes break. Some might be fine but just not been tested for lower temps but some not rated will almost certainly be dangerous.

There have been two batches of 60 with the 8.24app and two with 8.29. Looking at some of the tasks, all four batches have tasks that have got past the first zip on both Intel and AMD machines which rules out some causes of the tasks crashing but doesn't from where I am sitting say exactly what the problem is.

I've got one of these v8.24 tasks. It's survived one restart, so is there some difference to the tasks that almost always crashed on restart?


Impossible to say if the surviving one restart is due to any change yet. This test is to confirm that two particular ancillary files were not responsible for the failures that seemed to happen on all Intel machines. I would guess that if these run OK, there will be two or three other small batches to test the other ancillary files/to narrow down further what the issue is. Glenn is the one who could really answer that question but he may be too busy trying to find the answer right now!

Ah, a BT engineer told me this was why my 1979 phone line was rubbish. He said something about them coming loose. But for the price I'll stick to aluminium!


See Terry Pratchett.

The reason that the rich were so rich, Vimes reasoned, was because they managed to spend less money,” wrote Pratchett. “Take boots, for example. He earned thirty-eight dollars a month plus allowances. A really good pair of leather boots cost fifty dollars. But an affordable pair of boots, which were sort of okay for a season or two and then leaked like hell when the cardboard gave out, cost about ten dollars. Those were the kind of boots Vimes always bought, and wore until the soles were so thin that he could tell where he was in Ankh-Morpork on a foggy night by the feel of the cobbles. But the thing was that good boots lasted for years and years. A man who could afford fifty dollars had a pair of boots that’d still be keeping his feet dry in ten years’ time, while a poor man who could only afford cheap boots would have spent a hundred dollars on boots in the same time and would still have wet feet.

Both new batches appear to be the older "Weather At Home 2 (wah2) v8.24" application, so it looks like a bit of benchmarking is going on.
Small batch of 60 tasks. Checking a couple specific ancillary files for natural forcing I believe.

Small batch 1011 appears to have dropped. I have one running and 1st trickle has uploaded.

Sounds like progress as all your machines are Intel.

There is an issue with the current batch (1008/9) that means they are failing but only on Intel machines. So far they seem to behave on AMD ones. Glenn is doing some serious debugging work to track down the source of the problem. With luck the two remaining batches and a fixed 1008 with a new number might go out next week. Follow the thread for batch 1008 for news on this.

I mean seriously, warnings on chainsaws not to stop them with your genitals?!
Where do you buy your chainsaws from? Neither of mine came with any such warnings!

And health and safety measures are only common sense for someone who fully understands what is involved. A chainsaw for example can under certain circumstances kick up which is why I always wear a safety helmet while using mine and modern ones all have a safety chain brake that will stop the chain by hitting against the top hand in such situations. Someone with no knowledge of chainsaws could buy one of the old fashioned ones and have no idea how dangerous it is. Health and safety warnings and measures are designed to protect those who don't understand what is involved.

Starting to get some tasks from batch 1009 - I assume these are the test run.
I can confirm these are from the test batch of 100 tasks.

Edit: And I would guess they have all gone now so I won't get any unless there are failures.

I have deleted the last resend. It was a _2 so won't be sent again now. I have left the five started tasks from 1008 going and there is a resend from 1007 at 88%. I have also set the machine to no new tasks till I get some hints about the imminentness of the 100 tasks being released.

Edit:I think if BOINC were to cater for this type of test it would almost certainly mess something else up!

Edit2: Given the time I would not be surprised if the test doesn't arrive till Monday though I have been caught out before by batches being released over the weekend.

I believe the Intel runs are behaving correctly and failing. It's the AMD runs not behaving.
The only reason I haven't asked why is I almost certainly will not understand the answer! ;)

Thanks Glen. I will abort the two not started yet as credit isn't a issue for me.
I was clearly a bit premature with that as I have picked up one more resend from 1008.
