cpuburn lets you use 100% of all available cores, useful when stress-testing.

Download cpuburn from http:https://patrickmylund.com/projects/cpuburn/

If you have Go installed, you can run: go get github.com/pmylund/cpuburn (a cpuburn binary will be added to your GOPATH/bin folder)

Note: You do not need to have Go installed to run the stand-alone version.

Clone the repo:

git clone https://github.com/prehensilecode/cpuburn

Build it:

cd cpuburn
go build

which produces the executable cpuburn in the same directory.

  ./cpuburn (burn all available cores)
  ./cpuburn -n 2 (burn two cores)
  ./cpuburn -n 4 -u 5 (burn four cores, updating every five seconds)
