Yea, I suppose I could do that but I'm honestly here for the science and if Reddit has taught me anything, internet points aren't worth anything. 8-). The long WU's are producing results, and that might be helpful to researchers. So I let them run.

I've got a few long units now going on my 36hr boxes, they are coming up on the 46hour cutoff, I wonder what results they will provide.

I've set no new work for the other projects, and increased the buffer to half a day. This seems to make all my 90 CPU cores run Rosetta continuously. When I had a 0+3 hour buffer, I was running out of Rosetta and it was refusing to get any more. I think Boinc backs off if it sees a computation error, so it doesn't flood a server with mistakes.

Just between us girls

Speak for yourself, I'm above average size.

The frequency with which you talk about "size" in your posts to me -- and only me -- is disturbing.

Don't get your hopes up, it just happens you're the only one that called me a girl.

I think you'll find it's me on the receiving end

This is a detail about you that I didn't really need to know.

Taking things out of context for comic effect? Don't give up the day job.

A new issue.

Pi4 8GB running 3 Rosetta and 2 Einstein tasks. It has swapped the 2nd Rosetta and an Einstein out with a message "Waiting for memory". The currently running Rosetta task are using 1746MB and 665MB and the two Einsteins are 205MB each. According to top its still got 3GB of free memory. When I spotted it it was running 1 Rosetta and 2 Einstein with the 2nd Rosetta swapped out.

I wonder if its related to their requirement for 6.6GB free memory and BOINC is using that rather than the actual memory usage. Its BOINC 7.16.11

Update: A while later and the 1st Rosetta task failed so its back to normal. The Windows host that also ran it errored out so looks like a dud work unit. It was a miniprotein_relax8.

RAM loses its data every time you turn the power off.

No, it won't. Even with a ridiculously excessive amount of swap file usage, the actual volume of writes as a percentage of the drive's total capacity will only be a small fraction of the drive's rated DWPD (Drive Writes Per Day), and as long as there is plenty of free space on the drive the drive controller's wear levelling will also significantly prolong the life of the drive even further.

Yes, after several decades the drive will fail from all those writes due to the lack of system RAM, but most people don't keep their systems in use for that length of time.

Replacing a disk is a nuisance when you lose files and/or have to set up the OS again. RAM is way faster anyway.

I do a disk backup everytime I setup a new hd and keep it on 2 different larger hd's just in case, so no problems replacing a drive as I just plug inthe drive with the image and restore it and voila I am working again. The only requirement is that the new drive be no smaller than the original drive which is not a problem these days with drive prices dropping. AND new SSD drives are essentially ram chips anyway so they are catching up quickly to the pc's ram.

Been getting a lot of "Error while computing" .. any ideas?

For some time now there have been huge batches of work that produce nothing but errors. We also now have some Tasks that result in Validate errors as well.

CIA -- Thanks, for the tip. Waited approx. 15 mins., and they ran. Half w/out errors, thus far, the others failed.

The 6.5GB problem goes away on an 8GB machine if you set it to use 100% memory. It never actually uses 100% since everything overestimates. I just changed my old Boinc-only machines [1] and Rosettas downloaded and ran

This is actually a good point.

I found 95% is usually sufficient on my laptop as it happens, but for those for whom it isn't, it's worth going the whole hog

They are cheap nowadays, get a cheap 250gb one and just replace once it's done it's 100 thousand/million hours or what it is, the next one will be even cheaper

Replacing a disk is a nuisance when you lose files and/or have to set up the OS again. RAM is way faster anyway.

RAM loses its data every time you turn the power off.

We were talking about where RAM should be, in a swapfile on an SSD, or in real RAM. The swapfile is not saved when you turn the power off.

No, it won't. Even with a ridiculously excessive amount of swap file usage, the actual volume of writes as a percentage of the drive's total capacity will only be a small fraction of the drive's rated DWPD (Drive Writes Per Day), and as long as there is plenty of free space on the drive the drive controller's wear levelling will also significantly prolong the life of the drive even further.

Yes, after several decades the drive will fail from all those writes due to the lack of system RAM, but most people don't keep their systems in use for that length of time.

They wear faster than you think. My Crucial SSD is under 2 years old and states in the SMART data that it's used over a third of it's life. And that's without using much swapfile on it since I have loads of RAM.

I do a disk backup everytime I setup a new hd and keep it on 2 different larger hd's just in case, so no problems replacing a drive as I just plug inthe drive with the image and restore it and voila I am working again. The only requirement is that the new drive be no smaller than the original drive which is not a problem these days with drive prices dropping. AND new SSD drives are essentially ram chips anyway so they are catching up quickly to the pc's ram.

I meant more for a PC which you use for things other than Boinc. It takes me about two weeks to get everything back the way it was. And you always lose something important you did after the last backup.

The 6.5GB problem goes away on an 8GB machine if you set it to use 100% memory. It never actually uses 100% since everything overestimates. I just changed my old Boinc-only machines [1] and Rosettas downloaded and ran

This is actually a good point.

[Double take] I made a good point?

I found 95% is usually sufficient on my laptop as it happens, but for those for whom it isn't, it's worth going the whole hog

It's a pity Boinc won't accept 150%. Which isn't as silly as it sounds, if you have an NVME for the swapfile, you might not mind it dipping into that occasionally, so you can get another task in.

And there are HDDs that fail earlier than others. Their failure isn't representative of HDDs in general, and it's the same for your SSD.
SSDs don't wear out nearly as fast as you believe (just like HDDs, there are exceptions).

Many years ago The TechReport decided to test some consumer SSDs of the time until they died. Even the earliest to die lasted well beyond it's official rating, and the winner made it past it's official rating by a massive amount. Since then, while the endurance of each successive flash type has dropped, due to the increase in NAND capacity (and overprovisioning), along with improvements in wear levelling & OS recognition of SSDs, their reliability has improved.

I know you have your arsey moods, but that doesn't mean I don't take your points on their merit.
Then again, I'm probably wrong...

I've read many articles complaining that SSDs last nowhere near as long as HDDs. A few HDDs do fail unexpectedly, but SSDs wear out, because they have a finite number of writes. They cannot possibly last longer than that time.
