hpcom pthread codegeneration generated openmp code

Jul-10-15 06:14:11

Hi,
I am a little bit confused about the c-code I generate with following options

Code:

setDebugFlags("hpcom hpcomDump"); getErrorString(); 

setCommandLineOptions("+n=5 +hpcomScheduler=mcp +hpcomCode=pthreads"); getErrorString();

Nevertheless the following OPENMP define is created in all c-files. However as far as I can see, OpenMP is used nowhere.

Code:

#define HPCOM



#if defined(HPCOM) && !defined(_OPENMP)

  #error "HPCOM requires OpenMP or the results are wrong"

#endif

#if defined(_OPENMP)

  #include <omp.h>

#else

  /* dummy omp defines */

  #define omp_get_max_threads() 1

#endif

pthreads are created as expected:

Code:

...

// number of threads: 5

static int finished; //set to 1 if the hpcom-threads should be destroyed



static pthread_t odeThread_0;

static pthread_t odeThread_1;

...

Also openmp compilerflag is activated in the makefile

Code:

CC=gcc -fopenmp

For me it is not clear why openmp is neccessary when using pthreads? Or is it a bug in the codegeneration template?

Thanks for help
