Question
I am using an example of Intel TBB code I found on SO:
#include "tbb/blocked_range.h"
#include "tbb/parallel_for.h"
#include "tbb/task_scheduler_init.h"
#include <iostream>
#include <vector>
struct mytask {
mytask(size_t n)
:_n(n)
{}
void operator()() {
for (int i=0;i<1000000;++i) {} // Deliberately run slow
std::cerr << "[" << _n << "]";
}
size_t _n;
};
struct executor
{
executor(std::vector<mytask>& t) :_tasks(t)
{}
executor(executor& e,tbb::split) :_tasks(e._tasks)
{}
void operator()(const tbb::blocked_range<size_t>& r) const {
for (size_t i=r.begin();i!=r.end();++i)
_tasks[i]();
}
std::vector<mytask>& _tasks;
};
int main(int,char**) {
tbb::task_scheduler_init init; // Automatic number of threads
// tbb::task_scheduler_init init(2); // Explicit number of threads
std::vector<mytask> tasks;
for (int i=0;i<1000;++i){
tasks.push_back(mytask(i));
}
executor exec(tasks);
tbb::parallel_for(tbb::blocked_range<size_t>(0,tasks.size()),exec);
std::cerr << std::endl;
return 0;
}
The code builds fine, but when I go to run I get the error:
The program can't start because tbb_debug.dll is missing from your computer. Try reinstalling the program to fix this problem.
I think this is probably the path I need to set somewhere within VS2012:
C:\Program Files (x86)\Intel\Composer XE 2013 SP1\redist\ia32\tbb\vc11
because it contains tbb_debug.dll.
Where does this path need to be set?
EDIT: I tried setting in the "Executable directories" path section but that didnt work.
