Does anyone know the criteria needed to get these wu's on Einstein. I haven't managed to pick any up at all.

Old PC - DUAL Core, etc

Checked CPU model from sched_request, or may be fpops from benchmark

Same here, all I get is the High ones even though I'm not asking for them, won't send any low ones just the high ones ...

I have 2 hosts with "low" app:

Intel(R) Pentium(R) Dual CPU E2160 @ 1.80GHz
Intel(R) Pentium(R) 4 CPU 3.20GHz

A similar situation was with all previous paired applications

[edit]
Wingman info:
Intel(R) Core(TM)2 Quad CPU Q6600 @ 2.40GHz
AuthenticAMD Quad-Core AMD Opteron(tm) Processor 2376
AuthenticAMD AMD Opteron(TM) Processor 6220
Intel(R) Xeon(R) CPU X5550 @ 2.67GHz
Intel(R) Pentium(R) CPU N3710 @ 1.60GHz
AuthenticAMD AMD Athlon(tm) X4 860K Quad Core Processor
Intel(R) Core(TM) i3 CPU 540 @ 3.07GHz

Just tried an older core2Duo but it would not get any tasks either. That's the oldest one I have unfortunately so I'm out of luck... :)

I don't think that's true. Some days ago I suddenly got a bunch of tasks on my AMD FX 8320.
If you check the app site it does say that the apps seem to use AVX, so old PCs shouldn't/couldn't crunch them at all probably.
However, the last days I got none more, but I just found out that a half hour before a new task found a way to my host.
On the other side, getting highFreq-tasks seems to be impossible so far...

Edit:
Ok, forgot to read further, you seem to have get the app on your older pc... so it's not only a pure AVX app. Sorry.

<plan_class>AVX</plan_class> - This means nothing :o)

The application universally and automatically uses the capabilities of the CPU

Previous applications in the logs showed a regular expression for checking the CPU model (link in the last column in the host table). Now this is not in the logs.

- is from Jan and is about O1MD1G work, but the explanation looks similar with the exception that we can also get these tasks on some AMD CPU based systems.
I've picked up some O1Spot1TLo tasks on an 'old' AMD tri-core 2.1GHz Linux system, some on an E5520 based system and some on an i3-5005U. The i3 is a 14nm released in 2015 but is a dual core with HT. So old CPU's or small CPU's might be the key here.
