You can pass a static member function to a pthread, and an instance of an object as its argument. The idiom goes something like this:

class Parallel
{
private:
    pthread_t thread;

    static void * staticEntryPoint(void * c);
    void entryPoint();

public:
    void start();
};

void Parallel::start()
{
    pthread_create(&thread, NULL, Parallel::staticEntryPoint, this);
}

void * Parallel::staticEntryPoint(void * c)
{
    ((Parallel *) c)->entryPoint();
    return NULL;
}

void Parallel::entryPoint()
{
    // thread body
}

This is a pthread example. You can probably adapt it to use a std::thread without much difficulty.
