Added MiniCL, a limited subset of OpenCL, the open standard for parallel programming of heterogeneous systems.

Browse Source 
MiniCL includes a cross-platform run-time frontend based on pthreads, Win32 Threads, or libspe2 for Cell SPU.
It is there, to bridge the gap until OpenCL is more widely available.

See Bullet/Demos/VectorAdd, influenced by NVidia OpenCL Jumpstart Guide:

/*
* Vector types
*
* Note: OpenCL requires that all types be naturally aligned.
* This means that vector types must be naturally aligned.
* For example, a vector of four floats must be aligned to
* a 16 byte boundary (calculated as 4 * the natural 4-byte
* alignment of the float). The alignment qualifiers here
* will only function properly if your compiler supports them
* and if you don't actively work to defeat them. For example,
* in order for a cl_float4 to be 16 byte aligned in a struct,
* the start of the struct must itself be 16-byte aligned.
*
* Maintaining proper alignment is the user's responsibility.
