Currently, 80 percent of the world's top 25 supercomputers use Arm's software tools, with key customers including the US Department of Energy, NASA, a range of supercomputing national labs and universities, and private companies using HPC systems for their own scientific computation. Arm Forge is a unique toolset that provides developers with the ability to deal with systems with hundreds, thousands (and hundreds of thousands) of cores.
