Most Powerful And High Speed Computer In The World:
There are many powerful and high speed computer in the world. But powerful and high speed computer name is Fugaku.
Speed: 442 PFLOPS (per TOP500 Rmax), after upgrade; higher 2.0 EFLOPS on a different mixed-precision benchmark.
Cores: 7,630,848
Memory: HBM2 32 GiB/node
Storage: 1.6 TB NVMe SSD/16 nodes (L1) 150 PB shared Lustre FS (L2) Cloud storage services (L3)
Cost: US$1 billion (total programme cost)
Fugaku runs on two operating systems side by side: Linux and a ‘light-weight multi-kernel OS’ called IHK/McKernel. Linux handles Portable Operating System Interface (POSIX) compatible services, while McKernel runs high-performance simulations. It is designed to address high-priority social and scientific problems, such as weather forecasting, clean energy development, drug discovery, personalized medicine, and exploring the laws of quantum mechanics. Fugaku will use a "light-weight multi-kernel operating system" named IHK/McKernel. The operating system uses both Linux and the McKernel light-weight kernel operating simultaneously and side by side. The infrastructure that both kernels run on is termed the Interface for Heterogeneous Kernels (IHK). The high-performance simulations are run on McKernel, with Linux available for all other POSIX-compatible services.[14][15][16] Who uses a supercomputer? Supercomputers were originally used in applications related to national security, including nuclear weapons design and cryptography. Today they are also routinely employed by the
