In alternativa, si può usare stress-ng
. Ha uno stress test della CPU come uno dei tanti stress test integrati nello strumento. Lo stress test della cpu contiene molti diversi metodi di stress della CPU che coprono numeri interi, virgola mobile, operazioni a bit, calcolo misto, calcolo primo e una vasta gamma di calcoli.
Installa usando:
sudo apt-get install stress-ng
Per vedere i metodi di stress relativi alla CPU usare:
stress-ng --cpu-method which
Per eseguire il benchmark, ad esempio, prodotto matrix per 60 secondi su 4 thread CPU, utilizzare:
stress-ng --cpu 4 --cpu-method matrixprod --metrics-brief --perf -t 60
