1) Message boards : Number crunching : LLR2 installed on all big LLR projects (Message 143511)
Posted 5 days ago by Michael BeckerProject donor
my AMD Ryzen 9 3900X also performs poorly with the new LLR2 app at SR5, with 4x 3 core multithreading it needs ~35000s (including ~900s for 'Compressed 128 points to 7 products'), the old app did a task in ~20000s.

Thank you, maybe after 2 years of running the gpu got weaker.


I'm guessing you already tried rebooting the pc? Sometimes they just get lost and reduce their power, a reboot can fix it.

Cleaning of heatsink and fan is also recommended...

Nice feature :-)

but the number of 'Avg. cores/computer' seems to be incorrect, like this:
Intel(R) Core(TM) i7-7700K CPU @ 4.20GHz [Family 6 Model 158 Stepping 9] 138 8.98 5.19 46.58
This CPU has afaik 8 cores with HT on, how we get 8.98 ??
5) Message boards : Number crunching : New Badge Suggestion (Message 122816)
Posted 674 days ago by Michael BeckerProject donor
What about this: An 'unlucky' badge for 'found no prime a long time'
bronze after 2 months
silver - 4 months
gold - 6 months
..
.

but only if user is searching for primes.
if a user has only sieve work units, he should not get it

Yes, I'm loocking at LLR performance.
I will mainly crunch Cullen/Woodall, SoB, ESP and SR5.

Hi,

i want to replace my old I7 2600K, but I'm not sure which CPU i should take.
There are I7 6850K, 7800K, or 8700K
I will take G.Skill Trident Z DDR4-3200 CL14 DIMM

Some people say I7 7800K is poor because of a slow mesh cache.

Which CPU will generate the best throughput?
Any suggestion?

Michael

Thanks for this information.
So the score depends on the length of a prime that can be found?
The computer has much more to calculate FPS than 27, and /or the program is not as efficient as the other? Are optimizations possible?

Michael
