Intel Kills Knights Hill, Will Launch Xeon Phi Architecture for Exascale Computing

This site may earn affiliate commissions from the links on this page. Terms of use. In 2006, Intel decided to build a new GPU architecture, codenamed Larrabee. It didn’t work, so Intel decided to re-spin it as a manycore architecture dubbed Knights Ferry. While the first KNF processors were prototypes with literal GPU silicon still bolted on-die, follow-up chips like Knights Corner switched to a modified Pentium (P54C) architecture with x86 ISA support, 4-way SMT, and up to 1.2TFLOPS of double-precision performance. The Knights Landing architecture updated the CPU core ...

China, already dominant in supercomputers, shoots for an exascale prototype in 2017

Back in June, China debuted the world’s fastest supercomputer, the Sunway TaihuLight (pictured), with a Linpack benchmark result of 93 petaflop/s. That machine contains 40,960 locally developed ShenWei processors, each with 260 cores and roughly comparable with Intel’s Knight’s Landing Xeon Phi CPU. China also developed a 136GB/sec memory controller and custom interconnect that delivers 16GB/sec of peak bandwidth between nodes. Now China is working on a prototype exascale (1,000-petaflop) system that it aims to complete by the end of this year, according to state media. An exascale computer is ...
