'How to get the number of physical and logical cores in a batch file on a dual socket machine?
WMIC CPU Get NumberOfCores,NumberOfLogicalProcessors gets me most of what I want, but how do I store the combined output into a variable?
for /f "delims=" %%a in ('"WMIC CPU Get NumberOfCores,NumberOfLogicalProcessors /value"') do set /a "_%%a"
set _
Works for single socket machines only. The WMIC command returns cpu info on separate lines, i.e.
>WMIC CPU Get NumberOfCores,NumberOfLogicalProcessors /value
NumberOfCores=24
NumberOfLogicalProcessors=48
NumberOfCores=24
NumberOfLogicalProcessors=48
Solution 1:[1]
@echo off
setlocal
set /A "_NumberOfCores=_NumberOfLogicalProcessors=0"
for /F "tokens=1,2 delims==" %%a in ('WMIC CPU Get NumberOfCores^,NumberOfLogicalProcessors /value') do if "%%b" neq "" set /A "_%%a+=%%b"
set _
Note that wmic command output lines terminated in CR+CR+LF ASCII characters, even the empty lines, so it is necessary to check if the %%b part exists to avoid to process empty lines.
Solution 2:[2]
This will do it:
for /f "tokens=2,3 delims=," %%a in ('WMIC CPU Get NumberOfCores^,NumberOfLogicalProcessors /value /format:csv') do set "both=Cores=%%a Processors=%%b"
/format:csv changes up the format some, making it easier for us to manipulate, which I did in the above command.
