15 Million Node Neural Network on old 1GB PC

So, do you want proof that C/C++ is better than managed languages like C#?

I have recently started rewriting my Farve Extensive Connectivity Neural Network system in unmanaged C++. My own PC is broken so I am using my mother’s old PC, with 1GB RAM. On this PC, I just created an Extensive Connectivity neural network consisting of 15 Million nodes, and to allocate all that took just 20 seconds.

15 Million nodes.

Enter the Functor

The same program as in my previous post, but this time with a functor (overloaded () operator) to make the syntax very easy and C#-like:

#include
#include

using namespace std;

int main();
void myfunc();
void myfunc2();
void myfunc3();

class CDelegator
{
private:
std::vector _functions;

public:
void operator()()
{
Fire();
}

void operator+=(void (fn)())
{
AddFunction(fn);
}

void AddFunctionPtr(void (*fn)())
{
_functions.push_back(fn);
}

void AddFunction(void (fn)())
{
_functions.push_back(*fn);
}

void Fire()
{
vector::iterator iter;
for (iter = _functions.begin();
iter<_functions.end();
iter++)
{
cout << &*iter <>t;
return 0;
}

void myfunc()
{
cout << "MyFunc" << endl;
}

void myfunc2()
{
cout << "MyFunc2" << endl;
}

void myfunc3()
{
cout << "MyFunc3" << endl;
}

C / C++ wonderfulness

Some of you might know that I am re-learning myself C and C++. Why? Because C and C++ are the most powerful computer languages on the planet.

After chatting to a work colleague, Siegfried, I decided to try to implement delegate-like functionality in C. I am very happy to say that my small test program is a complete success.

Here is the code:


#include
#include

using namespace std;

int main();
void myfunc();
void myfunc2();
void myfunc3();

class CDelegator
{
private:
std::vector _functions;

public:
void AddFunctionPtr(void (*fn)())
{
_functions.push_back(fn);
}

void AddFunction(void (fn)())
{
_functions.push_back(*fn);
}

void Fire()
{
vector::iterator iter;
for (iter = _functions.begin();
iter<_functions.end();
iter++)
{
cout << &*iter << endl;

void(*func)();
func = *iter;
func();
}
}
};

int main()
{
CDelegator delegator;

delegator.AddFunction(myfunc);
delegator.AddFunction(myfunc2);
delegator.AddFunction(myfunc3);

delegator.Fire();

return 0;
}

void myfunc()
{
cout << "MyFunc" << endl;
}

void myfunc2()
{
cout << "MyFunc2" << endl;
}

void myfunc3()
{
cout << "MyFunc3" << endl;
}

Tip for ASSERT(afxCurrentResourceHandle != NULL);

If you are developing an application in C++ and you an assertion error on this line:

ASSERT(afxCurrentResourceHandle != NULL);

in atlmfc\include\afxwin1.inl

the problem might be that you are linking to a library that uses a different character set to your main application.

Go to project Properties – general, and make sure ‘Character Set’ is the same for your app and the libraries you are linking to.
