The backlog of high memory requirement jobs has been sent out. There will be occasional resends that go out but those will become less frequent over time.

Most jobs that go out now will be slightly larger than normal sized jobs. The backend pipeline is working hard to make this work available. Work will be available intermittently until things get caught up. It will be another 12-18 hours before work is readily available again.

Yes much appreciated. Thank you.

Hi knreed,
thank you for the workaround.
While my PC machines did not struggle with the memory leak problem, the RPi 3 did not well.
With the current workaround, I limit to 2 concurrent WUs on each RPi 3 (server configuration, no GUI) and they succeed to compute the complete WUs without swapping. In normal case, it is 4 concurrent OPN1 WUs without swapping.
Happy fixing,
Yves

If you're running an RPi 3 or similar memory-constrained system, putting swap space on zram, as counterintuitive as it seems, works beautifully. My Pi 3s got through the storm of huge jobs without any of them crashing, even when they sometimes had to wait for RAM, and I normally run four tasks on them. No manual intervention was needed.

Here's a script/service that sets it up for you with appropriate size settings: https://github.com/foundObjects/zram-swap

If I try it on a Pi running Ubuntu, it will complain when it tries to start the service the first time, but restarting it (sudo systemctl restart zram-swap) or rebooting it will work. I've been converting my Pi fleet to Ubuntu so that MPICH will interwork with my (also Ubuntu) x86 systems. MPICH becomes a real headache when your distros don't match. When they do match, it's just apt install mpich away.

The Pi 4, and especially the Pi 400, are surprisingly good number-crunchers. From a credit-hours per watt standpoint, nothing in my CPU zoo comes even close, and they are significantly faster than the throttled-down i7s in my old ThinkPads (which are also crunching). I can generally expect a Pi 400's BOINC RAC to be right around 900 or so, give or take a dozen or two - not bad for about seven watts measured at the wall socket.

The downside is that ARM on WCG gets you only OpenPandemics units and nothing else. Higher-capacity ARM systems like these really need more support from WCG - while a Pi 3 would choke on ARP, a Pi 4 or 400 could handle it better than those old laptops - to say nothing of a server/workstation-class ARM system like an Ampere Altra.
