Another of the key challenges identified inside the study of the University of Warwick is the fact that inside the rush to use GPGPUs, researchers still have not put sufficient energy into the development of technologies that actually could be utilized in parallel massive scale. The report shows that technology-based systems solve problems GPU three to 7 times faster than traditional CPU-based designs. However, it also stresses that as the number of processing elements connected together, the performance of GPU-based systems improve at a rate much slower than the machines created inside the style of BlueGene.
