I'm trying to go around the loop a fixed number of times, however I find I cannot seem to make this statement work with

REM @echo off
SET TotalCores=12
SET Sockets=2
SET SlaveNodes=4
SET /A mycores = %TotalCores% / %SlaveNodes%
FOR /L %i in (0,1,%SlaveNodes%) DO (call slavenode.bat  %i %mycores)

Why do I get the following issue?

SET /A mycores = 12 / 4
SlaveNodesi was unexpected at this time.

Is my formatting correct?

Remove the spaces, and use double percent signs around your loop variable:

REM @echo off
SET TotalCores=12
SET Sockets=2
SET SlaveNodes=4
SET /A mycores=%TotalCores%/%SlaveNodes%
FOR /L %%i in (0,1,%SlaveNodes%) DO (call slavenode.bat  %%i %mycores%)

set /a has no problems with the spaces. (while a simple set will make trouble...)
set /a didn't like the spaces either between the var names and assignment (=). It just caused a slightly different error.
One of the other issues is now how to pass in the number of cores. I'm having trouble with the accessing the number of cores using %2 in my slavenode.bat file.
@KenWhite: I have no problem with the spaces in Win7. @user673600: there is a %missing in this code. See my answer.
@Stephen: You're right; I missed one with the copy/paste. Fixed.

in batch files you must use double percentsigns for the for-variables:

FOR /L %%i in (0,1,%SlaveNodes%) DO (call slavenode.bat  %%i %mycores%)

(also you missed a % with your variable %mycores%)
