1) Message boards : 321 Prime Search : AMD Ryzen CPU Support (Message 110080)
Posted 650 days ago by csbyseti

I crunched PrimeGrid first time with llr321 and i see very slow crunching on the AMD Ryzen CPU.
The Stderr output file shows :
' ... Using AMD K10 FFT length 720K, Pass1=320, Pass2=2304, 5 threads ....'

Is it possible to activate newer CPU-Instruction Set for the AMD Ryzen?
