@Meinersbur Here is the c++ code test. Without the chunk size specified, the running result using OMPIRBuilder is correct.

  #include<iostream>
  
  int main() {
    int i, N = 10;
    float x = 0.0;
  
    #pragma omp for schedule(static, 2)
    for(i = 3; i <= N; i++) {
      x = x + i;
    }
  
    std::cout << "x = " << x << std::endl;
  
    return 0;
  }

  $ clang++ chunk-1.cpp -fopenmp -fopenmp-enable-irbuilder && ./a.out
  x = 7
  $ clang++ chunk-1.cpp -fopenmp && ./a.out
  x = 52
