SX-9
The SX-9 is a NEC SX supercomputer built by NEC Corporation. The SX-9 Series implements an SMP system in a compact node module and uses an enhanced version of the single chip vector processor that was introduced with the SX-6. The NEC SX-9 processors run at 3.2 GHz, with eight-way replicated vector pipes, each having two multiply units and two addition units; this results in a peak vector performance of 102.4 gigaFLOPS. For non-vectorized code, there is a scalar processor that runs at half the speed of the vector unit, i.e. 1.6 GHz. Up to 16 CPUs and 1 terabyte of memory may be used in a single node. Each node is packaged in an air-cooled cabinet, similar in size to a standard 42U computer rack. The SX-9 series ranges from the single-node SX-9/B system with 4 CPUs to the maximum expansion stage with 512 nodes, 8,192 CPUs, and 970 TFLOPS peak performance. There is up to 4 TB/s shared memory bandwidth per node and 2×128 GB/s node interconnect bandwidth. The operating ...

FLOPS
In computing, floating point operations per second (FLOPS, flops or flop/s) is a measure of computer performance, useful in fields of scientific computations that require floating-point calculations. For such cases, it is a more accurate measure than measuring instructions per second. Floating-point arithmetic Floating-point arithmetic is needed for very large or very small real numbers, or computations that require a large dynamic range. Floating-point representation is similar to scientific notation, except everything is carried out in base two, rather than base ten. The encoding scheme stores the sign, the exponent (in base two for Cray and VAX, base two or ten for IEEE floating point formats, and base 16 for IBM Floating Point Architecture) and the significand (number after the radix point). While several similar formats are in use, the most common is ANSI/IEEE Std. 754-1985. This standard defines the format for 32-bit numbers called ''single precision'', as well as 6 ...

SUPER-UX
SUPER-UX is a version of the Unix operating system from NEC that is used on its SX series of supercomputers. History The initial version of SUPER-UX was based on UNIX System V version 3.1 with features from BSD 4.3. The version for the NEC SX-9 was based on SVR4.2MP with BSD enhancements. Features SUPER-UX is a 64-bit UNIX operating system. It supports the Supercomputer File System (SFS). Earth Simulator The Earth Simulator uses a custom OS called "ESOS" (Earth Simulator Operating System) based on SUPER-UX. It has many enhanced features custom designed for the Earth Simulator which are not in the regular SUPER-UX OS. See also * EWS-UX EWS-UX is a Unix operating system used by NEC Corporation for its EWS-4800 line of engineering workstations. EWS-UX is based largely on versions of Unix System V supplemented with BSD software. It was widely used from the late 1980s to around 2 ... References External linksNEC Europe HPC

Unix-like
A Unix-like (sometimes referred to as UN*X or *nix) operating system is one that behaves in a manner similar to a Unix system, although not necessarily conforming to or being certified to any version of the Single UNIX Specification. A Unix-like application is one that behaves like the corresponding Unix command or shell. Although there are general philosophies for Unix design, there is no technical standard defining the term, and opinions can differ about the degree to which a particular operating system or application is Unix-like. Some well-known examples of Unix-like operating systems include Linux and BSD. These systems are often used on servers, as well as on personal computers and other devices. Many popular applications, such as the Apache web server and the Bash shell, are also designed to be used on Unix-like systems. One of the key features of Unix-like systems is their ability to support multiple users and processes simultaneously. This allows users to run multipl ...

NEC SX-6
The SX-6 is a NEC SX supercomputer built by NEC Corporation that debuted in 2001; the SX-6 was sold under license by Cray Inc. in the U.S. Each SX-6 single-node system contains up to eight vector processors, which share up to 64 GB of computer memory. The SX-6 processor is a single chip implementation containing a vector processor unit and a scalar processor fabricated in a 0.15 μm CMOS process with copper interconnects, whereas the SX-5 was a multi-chip implementation. The Earth Simulator is based on the SX-6 architecture. The vector processor is made up of eight vector pipeline units each with seventy-two 256-word vector registers. The vector unit performs add/shift, multiply, divide and logical operations. The scalar unit is 64 bits wide and contains a 64 KB cache. The scalar unit can decode, issue and complete four instructions per clock cycle. Branch prediction and speculative execution is supported. A multi-node system is configured by interconnecting up to 128 single-node s ...
