Convert a simple sequential program to parallel

I have a simple application written in Java (less than 100 lines with comments). It finds the determinant of any NxN matrix in a sequential order (one thread only). It does that by calling a function recursively until the matrix is 2x2 then it finds the determinant. I need somebody to create a parallel version of it, meaning that, the code would work in multi-threads not only in one thread. It could be done using the Fork/Join techniques (which is a parallel version of familiar divide−and−conquer algorithms). I'll send you the code after the award, or by PM if requested. CONDITIONS: - You must be an expert in Java and techniques of recursion and multi-threading. - You must know how Determinants work mathematically, to be able to understand the code. - The running time of the new parallel version MUST be faster than the current sequential one. - I prefer using a library called "JSR166" (found here: [login to view URL] under the heading "maintenance updates", and I also attached a good paper explaining it). However, if you will use your way you should be 100% sure that it's good and powerful. - I need the project to be done in 1-2 days maximum, less is better and has the priority to award. - My budget is $100. - You should explain the code to me and fix any problem arises. I need a quick communication. - The code must run on Eclipse and must be commented, clear and simple.
