I believe lots of the work comes through the Robetta server so it comes from outside the Bakerlab. I wouldn't have thought they will know what work is coming through that until it arrives.

That work is only a small percentage of the work that is usually available.

I am using a 4GB Pi 4 purely for Rosetta and have today started getting error messages relating to insufficient memory. It's been working fine up until today if I exclude it running out of work units overnight.

Message from server: Rosetta needs 6675.72MB RAM but only 3653.61MB is available for use.

I am aware that there appears to a lull of new work units but the sudden appearance of additional memory demands is of greater interest. I hope this is not going to render the smaller boxes such as the Pi's obsolete.

Homepage says 65,000 tasks are available and I just got lots of tasks on my AMD Ryzen 5 2500U laptop.
None were Robetta tasks. Some resends but also some new ones.

The current new Tasks i've got running (3cl_9mr_FG...) are using very little RAM, less than 300MB each.

My Pi has collected one unit (I would have expected about 8) within the past 20 minutes but the error concerning memory remains.

OK, my Pi knows I am talking about it and has subsequently acquired more work units.

The error message relating to insufficient memory persists however, so I have referred this to Balena in case it is an update with their client that has introduced it.

sudden appearance of additional memory demands

Not just memory: I’m now seeing

Rosetta needs 5472.67MB more disk space

(on an admittedly very small partition set aside for the BOINC data directory, but it’s been fine for the last year) – so it looks like the new batch is unusually resource-hungry…

I have the same problem: "Message from server: Rosetta needs 6675.72MB RAM but only 3432.76MB is available for use."
I use a Linux workstation with 12GB memory and 12 cores. I have never seen such message before.

My PC had a shortage of memory message and only ran one of four WUs although it was only using 3.7GB of 8GB RAM. In Windows 10, I set Virtual Memory (page files) to 10000MB, upper and lower limits. The PC is now running four WUs instead of just one.

With 12 cores you need more than 16GB of RAM- a Single Task can require over 4GB of RAM, although 1 to 1.3GB is more common.
For a while now the memory requirements for Tasks have been very low, but we did get a batch of work that required over 1GB of RAM shortly before we ran out of work for a while there.

With my 12 cores/threads & 0.2 day cache, the most disk space i've seen needed for Rosetta has been around 2.7GB. Usually it's around 2.2GB or less.

I've been doing Rosetta well enough for some time but now it seems greater than the 4gb installed RAM is needed for current projects.
Is this correct and the large swap file not any good?

Homepage says 65,000 tasks are available and I just got lots of tasks on my AMD Ryzen 5 2500U laptop.
None were Robetta tasks. Some resends but also some new ones.

Grabbed one lot of 11 then.
Within the last half hour I grabbed another 3 lots of 11, 2 of which were Robetta, but no more left to get now.

My Pi 4 rig that was in difficulty earlier seems to have sorted itself out although it did experience a number of download errors beforehand. I've now got a cache of 2 days work so unless a number of those abort I should be OK while everything stabilises again.

Doesn't work if you use a wristwatch

What’s a wristwatch, Grandad? ;-⁠)

What do you do, take your phone out of your pocket? That's a backwards step.

will "bogeys at your 2 o'clock position" ever fade out due to the use of digital clocks? Or will we always have analogue ones?

Maybe more due to the removal of humans from air combat. Having simpler mechanisms, analogue clocks might make a comeback after the apocalypse…

I play Fallout 4. Apocalypses are fun! Although there are a few benefits in the game that break the laws of physics so would be difficult to implement in real life.

Wasn't really paying attention but 4-5hrs later (~4hrs ago) more came on stream and 1m+ queued more recently

I'm not getting out of memory or disk space messages, the tasks are simply "waiting to start."

I I suspended all other tasks from other projects, received a number of new Rosetta tasks. They all refused to do anything other than just sit there.

An idle CPU is not a good thing when it should be maxed out running tasks.

My odroidC4 does not get anymore tasks.
i got a note: Rosetta required 6.x GB suddenly. Around 3.7 available.
I dont understand why this is, all the other days i could run 4 tasks without any problem.
Now i do not get even one tasks.
Also i have 5GB swap but Rosetta does not use any space of it, but this was also before i think.

My other two computers have again new tasks, all okay there.
Some ideas ?
Thanks a lot.

the tasks are simply "waiting to start."

At the risk of sounding incredibly pernickety: is it ‘Ready to start’ or ‘Waiting to run’? (They mean subtly different things, and ‘waiting to start’ isn’t a state a task can be in…)

If the former, this sounds a lot like a problem that was reported recently: tasks sit ‘Ready to start’ even though nothing else is running and there’s no obvious reason why they can’t run. I’m not sure we ever understood the root cause of the issue at the time, but it seemed that the tasks wanted more memory than was available (even if in that case we’d expect them to say ‘Waiting for memory’). Fiddling with the memory settings in Computing preferences seemed to get them going. If that doesn’t work, try selecting the Event Log options cpu_sched_debug and mem_usage_debug and looking in the Event Log for clues.

There’s a new batch of work units today that are marked as needing 6.6 GB of memory, so the server won’t even send them to hosts it knows have less than that. I’m not sure swap space is taken into account in that decision. You might want to consider a different project until Rosetta comes back with tasks suited to smaller machines.

The i7 has only picked up resends of older tasks (with much smaller memory requirements).

The MacBook has returned a lot of errors lately. Might be a platform bug; who knows.
