Double-precision CPUs vs. Single-precision GPUs; HPL vs. HPL-AI HPC Benchmarks; Traditional vs. AI Supercomputers

If you’ve wondered why GPUs are faster than CPUs, in part it’s because GPUs are asked to do less – or, to be more precise, to be less precise. Next question: So if GPUs are faster than CPUs, why aren’t GPUs  the mainstream, baseline processor used in HPC server clusters? Again, in part it gets […]

Summit Supercomputer Triples Performance Record on new HPL-AI Benchmark

“Using HPL-AI, a new approach to benchmarking AI supercomputers, ORNL’s Summit system has achieved unprecedented performance levels of 445 petaflops or nearly half an exaflops. That compares with the system’s official performance of 148 petaflops announced in the new TOP500 list of the world’s fastest supercomputers.”

Epic HPC Road Trip Continues to Sandia National Lab

In this special guest feature, Dan Olds from OrionX continues his Epic HPC Road Trip series with a stop at Sandia National Laboratories in New Mexico. “Ken discussed how Sandia is hoping to stimulate more of a system-on-a-chip type of technology where extra CPU real estate might be better utilized for better HPC componentry and customization.”
