I have /Qparallel set.
Yes, it's somewhat surprising there is no "=".
This is not to say that I had much success with the option on that compiler version. By that time, most of the development effort was going into Parallel Studio.
You can do that with this command-line:--
icl -c /Qpar-threshold:99 /Qparallel test.cpp
This option does not work for Parallel Studio C++ compilers, but will work for Professional C++ compilers. See if you are using Parallel Studio compiler.
