hey i have also same problem with thread ID
i am not able to get thread ID can i any one can guide?
here is my code and compile information though it gives CPU number but i
donot get thread id. i tried ExecThread and Thread in --debug-flags
using x86
If any one can help
/*
Compile: g++ -g -O3 -fopenmp -c -o test_omp.o arraySummation_omp.cpp
Link: g++ -static -o test_omp test_omp.o -lgomp /opt/m5threads-
1118adb7cdad_X86/pthread.o -lgomp
Run: gem5x86.opt --debug-flags=Exec,ExecTicks
/home/akt0001/GEM5/configs/example/se.py -n 4 -c test_omp --options="

*/
#include <iostream>
#include <cstdlib>
#include <omp.h>
#include <pthread.h>
using namespace std;
int main(int argc, const char **argv)
{
if (argc != 3){
cout << "Usage: ./arraySummation_omp <nthreads> <size>" <<
endl;
}
int nthreads = atoi(argv[1]);
if (nthreads < 1){
cout << "nthreads must be 1 or more" << endl;
}
int size = atoi(argv[2]);
if (size < 1){
cout << "size must be more than 1" << endl;
}
cout << "size" << size << endl;
omp_set_num_threads(nthreads);
float a[size], b[size], c[size];
float temp = 0;
for (int i = 0; i< size; i++){
a[i] = 1;
b[i] = 2;
c[i] = 0;
}
#pragma omp parallel for
for (int i = 0; i< size; i++){
c[i] = a[i] + b[i];
}
for (int i = 0; i < size; i++) temp = c[i] + temp;
cout << "Addition of two array is " << temp << endl;
}
