You should also delete "CPU" on the title page at the genefer-15 line

So you mean with HT on Boinc is still using all 8 cores (16 threads) even when set to use 87.5%) for running llr. I thought it would only use 7 cores (14 threads).

So how can i test the real difference between HT on and HT off? (cores vs. threads)

Thanks for clarification of my rather stupid assumptions.

You are right, with 12 (out of 16) cores i mean threads (in boinctasks they are abbreviated as "C").

I use 14 threads (HT on) for Boinc (87.5%). 12 for one llr wu, 2 for genefer.
With HT off 6 (full cores?) for one llr wu and 1 for genefer (7 cores for Boinc/87.5%).

I tried this two settings on every llr subprojects (except SGS and PPSE) and found that llr runs with HT on on my system definitely faster than with HT off.

Hope this clarifies the confusion. Thanks also for your support

My i7-5960X 8/16 cores 32Gb memory runs LLR Wus faster with hyperthreading and multithreading on (12 c per wu).

e.g.: llrESP 12c (HT and MT on) around 2h 30m per wu
llrESP 6c (HT off MT on) around 3h+ per wu
this also goes for larger llr wus

so this seems to indicate that some cpus are better with both HT and MT set to on, or is there an error on my side?

You can change this parameter on PrimeGrids website page under your account -->edit preferences. And don't forget to update the new preferences from the BOINC manager.

Kind regards FXH
