Compiling

CMake is required to generate flags.h, link static OpenCL library and include headers.
gcc is the recommended compiler because I used __VERSION__ macro in main(). Any C++ compilers with this macro can compile the project, and if yours don't have it, you can edit my code.
However the C++ compiler should support OpenMP.

You also need Boost. Download Boost from their site and decompress in lib dir. You need lib/boost/boost.
Static OpenCL library needs to be linked as well. Take a look at this for Windows

Dim's Pascal Pythagoras theorem benchmark

Let a = pyth(b, c) be the syntax of Pythagoras theorem such that if a = pyth(3, 4) then a equals to 5.
Let list[n] be the syntax of retrieving the n-th element in a list such that [1, 2][0] -> 1.
Let the first index of any list be 0. So list[0] accesses the first element in the list.

The benchmark works like this:

1. Declare n = 2
2. Repeat until time measured >5s and step is 1:
   1. Declare list [1..n]
   2. Start measuring time
   3. Repeat until size of a is 1:
      1. For i = 0 to (size of list)-1:
         • a[i] = pyth(a[i], a[i+1])
      2. Remove last element in a
   4. Stop measuring time
   5. n += 1

n is the final score.

More details:

• Target is the time used to determine whether a test is successful or not.
  • If a test took >Targetms to execute, it is considered a fail and will step down.
• Step limit is the time used to determine whether the next test should step up or not.
  • If Step limit < current test's elapsed time < Target then step up.
