loops - Trying to find amount of CPU cores in batch file

Question

Below is working code I have been using but as you can see it uses the environment variable for amount of processors which is usually cores * 2 on most computers these days. Is there a way I can do something similar to base my loop on the amount of cores in the cpu and/or how can I edit my loop to divide the amount of processors by 2?

set loopcount=%NUMBER_OF_PROCESSORS%
:loop
START "Batch Script" MyProgram.exe
set /a loopcount=loopcount-1
if %loopcount%==0 goto exitloop
goto loop
:exitloop

Answer 1

For any question that amounts to "how can I find out information about my computer?", the answer is always to use wmic.

for /F "delims=" %%A in ('wmic cpu get NumberOfCores /format:value ^| find "NumberOfCores"') do set %%A
for /L %%A in (1,1,%NumberOfCores%) do start "Batch Script" MyProgram.exe

Of course, if you're looking for a way to do math in batch, just use set /a.

set /a loopcount=%NUMBER_OF_PROCESSORS%/2
