Are supercomputers based more upon CPUs or GPUs?

Until recently, the past decade or 2, CPUs (and cores) were more important. For certain problem applications, GPUs provide a boost, but CPUs still remain important. The problem most people fail to realize about supercomputers is that you have to h... read more

Supercomputers have always focused on their ability to perform fast Floating Point calculations. GPUs are designed specifically to perform high speed & high volume FPS. The CPU can do these tasks, but dedicated GPUs are designed to push FLOPS to the maximum. So, it’s the GPUs that do the FLOPS & the CPUs that set up the work for the GPUs. read more

In addition to a thriving CUDA development ecosystem, which has pushed GPU computing to an ever-growing list of systems and applications, GPU based supercomputers keep pushing forward, most recently, with the addition to the NVIDIA Tesla K80 accelerators. read more

Titan is an upgrade of Jaguar, a previous supercomputer at Oak Ridge, that uses graphics processing units (GPUs) in addition to conventional central processing units (CPUs). Titan is the first such hybrid to perform over 10 petaFLOPS. read more
