C# – How to test 500 trillion combinations in less than 6 hours of execution

I now have a PHP script loop that iterates through a combination of a set of arrays. I can test 1 out of 6.1 billion total combinations of 500 trillion in an hour with a simple PHP script. Is it possible to write a program in any language running on an average PC today, capable of testing all 500 trillion combinations of multiple arrays in less than 6 hours?

Also, I don’t have the resources to use distributed or cluster computing for this task. What kind of yield can you get by converting code to multithreaded Java/C#?

Thanks
