Run only recognize single core on ARM machine, getCpuInfofunction could not identify the correct cores #60

Closed longerzone closed 2 years ago

longerzone commented 6 years ago

I tried to run unixbench on my ARM machine, but I found it only run single core score, and then ended. And the running log shows : 0 CPUs in system; running 1 parallel copy of tests ... ... System Benchmark Index Score ... and then ended!

The reason is getCpuInfo function in Run script will read these info from /proc/cpuinfo:

processor : 0 ... model : 85 model name : Intel(R) Xeon(R) Gold ... ... flags : fpu vme de pse tsc msr pae mce ... bogomips : 4399.96 ...

Bug a typical /proc/cpuinfo on ARM machine will be like:

Processor : ARMv7 Processor rev 2 (v7l) BogoMIPS : 2007.04 Features : swp half thumb fastmult vfp edsp vfpv3 vfpv3d16 CPU implementer : 0x41 CPU architecture: 7 CPU variant : 0x2 CPU part : 0xc09 CPU revision : 2

So the getCpuInfo function could not recongnize the correct cores because of the key words "model/model name/flags/bogomips" is not matched on ARM platform!
