Usually it refers to a GPU that has some characteristics that make them suitable to high throughput parallel computation, as full IEEE754 compatibility (the way X86 CPUs represent floating point numbers), branch control, an easy to program for API... AMD used to have an API called "close to the metal" that was a nightmare, nVidia has CUDA that is easier to work with... Apple and the Kronos Workgroup (the people behind OpenGL) are trying to popularize OpenCL, that's what probably WiiU will use.
It means that you can use your GPU to do some work your CPU could be short in computational capabilities, work that can be divided in a huge number of small chunks, lots of threads, as IA or physics work.
