PrimeGrid was chosen as the sprint 4 hours ago.

 How can a sprint have wu's that take 10 days opps make that 7 days . I got 16 cores working on 3 they started out showing 10 or 11 days to do .

For PrimeGrid multi thread tasks, you will get the best performance by disabling hyper threading or setting BOINC to use 50% of your CPU and running one task on all available cores.
When Formula BOINC chooses PrimeGrid for a sprint there are no restrictions on which sub task to run, so AP27 tasks on GPU are generally the highest "PPD" right now.  You can do well in a sprint without running any CPU tasks.

Just to be clear, Ramanujan Machine is the sprint going on right now not PrimeGrid. 
 
With PG hyperthread off unless you are running sieve tasks, multithread is best for LLR2 tasks.
Also want to try to fit the tasks in the CPUs L3 cache. Small LLR2 maybe able to do 2 or more depending on CPU and what tasks.

Bill is that E cores and hyperthreading or just Ecore . I got a i7-12700F its not like the older ones where you just turn off hyperthreading , Think I can turn off E cores to but still Learning Motherboard it did not come with a manual . And I got no idea how to fit the tasks in the CPUs L3 cache . Not really into crunching numbers Looks like will mostly crunch Rosetta and SiDock .

I have no E cores myself but I have read it is best not to use them. Not sure how to make that happen.
I am using x99 and x299 boards and an older 2P xeon rig. 
As far as fitting tasks in L3 on PG task preference  it tells you how big the tasks are. (FFT size)
Recent average CPU time: 113:33:14
FFT sizes: 2560K to 3072K (uses up to 24576K cache per task). So that would be around 25mb 
Most intel CPUs it will fit or it won't. AMD CPUs can be a bit tricky they way the cores interact with the cache.
If you do ever want to run PG in the future, as of now CPUs with AVX512 run the fastest, Intel X299 or the new AMD CPUs
 
WCG still has medical tasks too and I have been getting steady tasks.
