12) Message boards : Number crunching : Strange timings on AMD 3700X (Message 155999)
Posted 60 days ago by Profile Crun-chiProject donor
I run all tests under Linux and using mprime. Found strange timings but only on 640K and 8 workers, one cpu core per worker (SMT is disabled, Linux is OS) and found no explanation. Any idea?

Prime95 64-bit version 30.8, RdtscTiming=1
Timings for 640K all-complex FFT length (8 cores, 1 worker): 0.43 ms. Throughput: 2317.71 iter/sec.

This machine is dedicated just for crunching and nothing else. Also as you can see in red color, not always same core are faster then rest of them.

Just saw the news about Pavel Atnashev's prime! Congrats!

https://primes.utm.edu/primes/page.php?id=133721

Very exciting to find one missed as a result of adaptive replication. Probably the first of many with the smaller n values coming up soon.

I wonder how many will be found, and I wonder how many of those will be large enough for T5K.


Can you explain what is adaptive replication?

May prime find you !
The server is not broken FOR YOU!

I think the server is definitely broken... no primes for AtP since the 19th!! did you guys shut everything down? or maybe someone walked under a ladder or something?

I'll try some of this scotch and see if that helps!

From day I found PPSE, I mode to Mega.. and nothing...
