Simulink ERT Codegen for (openMP) Parelel Run

Hi,
I have simulink model thats contains multiple reference models. One them has contionus time solver others have discrete sample.
C++ code(ERT config) is generated from simulink model witouth problem. Also code is builded in Visual studio and .exe is running properly. Both exe and simulink model giving same results.
I want to run model for different input for Monte Carlo analysis. Hence, i added for loop above to step function which changes inputs. It also works.
The issue here is that when I try parelel for loop (used omp lib, such as added "#pragma omp parelel for" ), it is running at different threads. However, for same inputs results are different.
Is there any way to make simulink generated code to run on parelel for loop with different inputs?
