Suddenly I'm only receiving single threaded tasks and not the 3 threaded MT tasks as normal according my settings. Any idea why?

I did too, but the last seem to be finishing up now. Several took more than a day. Only happened to one of my computers though.

The last 5 WUs I got today are MT tasks again, so far so good.

To avoid a mix of single thread and multi thread WUs change in your Milkyway@home preferences "Max # of threads for each MilkyWay@home task" from "no limit" to the number of cores you want to use for each task.

I did change it to 3 and it worked until 2-3 days ago where I then got single tread tasks. Now I'm using app_config, and it seems to work.

I usually make sure the Options > Computing Preferences (Advanced view) uses 2 cores (or > 34% and < 49% on my old 6-core PC).

On the BOINC Advanced View, my Status appends (2 CPUs) for the dual-threaded work units. If the (2 CPUs) is not present, I assume that indicates a single-threaded work unit.

I sometimes receive a few single-threaded tasks even with "Max # of threads for each MilkyWay@home task" set to 2. Not sure why!

Whether you get single- or multi-threaded work units might depend upon your Computing Preferences, such that MilkyWay@home won't assign work units with more threads than your Computing Preferences number of cores. It might also depend on what BOINC projects are active at the time the request for more tasks is made, because I often run multiple BOINC projects.

I do not have an app config XML in C:\ProgramData\BOINC\projects\milkyway.cs.rpi.edu_milkyway

One box (my main desktop, 5950X) not getting (mt) tasks now... well for maybe a month...

https://milkyway.cs.rpi.edu/milkyway/show_host_detail.php?hostid=1029692

I have another box(5900X) that has the same OS, same virtualization (none) and it's getting mt tasks.
I've looked at this till I'm blue in the face so it is likely something very obvious that I'm just overlooking. Any thoughts?

Thanx, Skip

PS: All are Linux Mint boxes.

Not getting MT tasks is not an issue, it's actually something good. MT seems very inefficient, so unless you want MT tasks for some special reason, I'd recommend to run Milkyway in single thread mode. This also makes it a lot easier to run Milkyway tasks together with other projects, which are usually ST too.
