OoO workshop has been successfully held on last Sunday thanks to SGI Japan.

Syoyo, the founder of this event, had predicted the future of GPU in his presentation using a comparison of two charts which are about the Nikkei 225 index and the speed of GPU. Detail is
here.

This is the most interesting prediction about GPU I ever met. Nowadays, CPU is speeding up much faster than GPU and its power consumption is still low against GPU's.

I think that FPGA can be a competitor of CPU rather than GPU in near future. The number of gates in FPGA has become very large so that it could be used for development of very complex processor such as Raytracing Processing Unit as known as RPU.
