I have a problem in organizing concurrent thread launch. My program
structure is the following:
#include <iostream>
#include
using namespace std;
class Worker
{
private:
boost::thread m_Thread;
public:
Worker() { /* the thread is not-a-thread until we call start() */ }
void start(int N) { m_Thread =
boost::thread(&Worker::processQueue, this, N); }
void join() { m_Thread.join(); }
void processQueue(unsigned N) { /* Do some long long stuff... */ }
};
int main(int argc, char* argv[])
{
Worker worker_1,
worker_2,
worker_3,
worker_4;
// How to start threads and join them in order
// to make constantly two of them running?
return 0;
}
I have different threads which have to work on completely different
input and output data (non critical sections): an atomic operation per
thread, each one with different time execution but everyone with an
intense use of the CPU.
Let's say I have 10 operations to perform (10 threads): I would like to
run concurrently only 2 threads because of resource consumption.
My problem is that when a threads ends its execution, I would like to
suddenly start another thread performing operation 3, in order to have
constantly 2 threads working, and so on until the end of operations.
How can I achieve this? I thought to insert my threads into a
vector...but I have no idea on how start and join them in order to
obtain what described above.
Can anyone post me a little example?
Thanks in advance.
