SVE

Today ARM is announcing an update to their line of architecture license products. With the goal of moving ARM more into the server, the data center, and high-performance computing, the new license add-on tackles a fundamental data center and HPC issue: vector compute. ARM v8-A with Scalable Vector Extensions won’t be part of any ARM microarchitecture license today, but for the semiconductor companies that build their own cores with the instruction set, this could see ARM move up into the HPC markets. Fujitsu is the first public licensee on board, with plans to include ARM v8-A cores with SVE in the Post-K RIKEN supercomputer in 2020. Scalable Vector Extensions (SVE) will be a flexible addition to the ISA, and support from 128-bit to 2048-bit. ARM...
