On WIN x86-64 systems, BURP should use 2 CPUs ... as the current software that runs on just one CPU keeps getting stuck in the 96% ish area of work unit completion.

Forcing 2 CPUs, and a modest rewrite of the rendering code to work with 2 CPUs may just eliminate a lot of grief.

I have not been able to complete a work unit since the Blender 4.78 software become defacto.

Mull over the idea, for now it seems to have merit.

Minor update, I have succeeded in getting 2 work units done.

A workable "work around" it to give the blender processes (as there are 2 of them on Windows x86 systems) "Normal" but not "Real Time" priority.

TASK MANAGER --> [Run As Administrator] --> "Processes" -->

--> 'select blender' (> 50 mb of RAM) --> (other mouse button) "Set Priority"

--> "Above Normal"

Blender needs to be changed to run on 2 CPUs, as it will speed it up -- and in being an exclusive BOINC process on many PCs -- run much better.

The problem of workunit completion is ongoing

-- The checkpointing has gotten better, but it is not fixed

-- Other bugs that make work unit completion a problem will take a while to fix

It isn't actually stuck, it is just that progress reports for experimental Cycles sessions isn't particularly accurate yet and very quickly goes to 98% or thereabouts. The WU is actually rendering just fine.

That said there are actually plans on enabling multithreading in the normal clients once Sunflower is complete.
