I needed to perform a stress-test on a Windows Server with many CPUs. There used to be a tool named “consume.exe” in the Windows 2003 Resource Kit. I unfortunately did not keep a copy of this toolkit. D’oh!
Along comes Mark Russinovich to the rescue (as always) with Sysinternals! CPUstres is the tool to use for this now: https://docs.microsoft.com/en-us/sysinternals/downloads/cpustres
