Nvidia’s Steve Scott has started a blog, and this week he’s describing how the Titan supercomputer is an important milestone on the road to Exascale.
The next-generation Kepler GPUs used in the Titan system will provide more than one teraflop of performance per chip. In heterogeneous computing, the GPU can perform the heavy lifting, executing the parallel work with very low power, and the CPU can then quickly execute the serial work that’s left over. This is the only hope of getting to exascale computing at reasonable cost and power.
