Brand: Hitachi

The Hitachi HA-1100 is a high-performance supercomputer introduced by Hitachi Ltd. In 1997. It was designed to compete with other top-tier supercomputers of that time, including the Cray T3D and the IBM SP.The HA-1100 utilized a non-uniform memory access (NUMA) architecture, which allowed for more efficient use of memory and improved overall system performance. Each node of the HA-1100 contained four 200 MHz MIPS R14000 processors, as well as 128 MB of memory.The HA-1100 used a proprietary interconnect technology called Scalable Network Bus (SNB) to connect the nodes, offering a theoretical peak performance of up to 700 gigaflops (GF) for a 128-node system. It was one of the first supercomputers to incorporate advanced cooling technologies, such as liquid cooling, to efficiently dissipate the heat generated by the massive processing power.The HA-1100 was known for its high-performance capabilities in various applications, such as fluid dynamics simulations, climate modeling, and weather forecasting. It was used by many national research labs, scientific institutions, and government agencies around the world.Overall, the Hitachi HA-1100 was a pioneering supercomputer in many ways, and its advanced architecture was a precursor to the modern supercomputers that followed. However, with the introduction of new technologies and architecture styles such as Graphics Processing Units (GPUs), the HA-1100 became less common in the supercomputing landscape over time.
