| | Vector processor - Wikipedia, the free encyclopedia |
 | | Vector processors were common in the scientific computing area, where they formed the basis of most supercomputers through the 1980s and into the 1990s, but general increases in performance and processor design saw the near disappearance of the vector processor as a general-purpose CPU. | | | A vector processor, or array processor, is a CPU design that is able to run mathematical operations on multiple data elements simultaneously. | | | The first successful implementation of a vector processor appears to be the CDC STAR-100 and the Texas Instruments Advanced Scientific Computer. |

| | Vector processing system for processing plural vector instruction streams - Patent 4849882 |
| | For the instruction processing unit of a general purpose computer, the memory ports are portions for receiving requests for access to main storage, and are always operative. | | | If a vector instruction which has been sent to the resource management circuit 4a is an instruction to make use of the memory port logic units, the management circuit 4a examines the status of the memory port logic units in the systems a and b via the paths 26 and 27. | | | If a vector instruction which has been sent to the resource management circuit 4a via the path 20 is an instruction to make use of an arithmetic and logic unit, the arithmetic and logic circuit to be used is started via a path 28 unless the arithmetic circuits are not all busy. |

| | The vector registers form the major computational registers of the computer, since they provide for the high speed vector processing of data. | | | Basically, a vector machine is one which deals with these ordered sets of data by virtue of its hardware organization, rather than by a software program and indexing, thus attaining a higher speed of operation. | | | The length of vectors associated with the solution of a given problem is of course determined by the nature of the problem. |

| | [Beowulf] Vector processing on AMD 64 |
| | Vector computing on the microprocessor is almost a different beast from traditional vector computing in that vectors are defined width-wise rather than length-wise. | | | Unlike the Cray ISA, which loads words in sequence up to the vector length (64x64 or 128x64) from memory with a single instruction, the microprocessors load and computes on one wide word at a time (prefetching functions as a pseudo-vector load)... | | | The totality of the Cray ISA and architecture is only poorly emulated by the vector operations on the various "vectorizing" microprocessoers. |

| | High-performance Linux clustering, Part 1: Clustering fundamentals |
| | To understand HPC hardware, it is useful to contrast the vector computing paradigm with the cluster paradigm. | | | Fundamentally, both vector and scalar processors execute instructions based on a clock; what sets them apart is the ability of vector processors to parallelize computations involving vectors (such as matrix multiplication), which are commonly used in High Performance Computing. | | | Vector processor systems deliver high performance and were the dominant HPC architecture in the 1980s and early 1990s, but clusters have become far more popular in recent years. |

| | Vector Processing |
| | By the end of the 1960's, it was possible to build multiple pipelined functional units, but the fetch and decode of instructions from memory was too slow to permit them to be fully exploited. | | | As with most architectural techniques for achieving high performance, it exploits regularities in the structure of computation, in this case, the fact that many codes contain loops that range over linear arrays of data performing symmetric operations. | | | Applying a single instruction to multiple data elements (SIMD) is one simple and logical way to leverage limited instruction bandwidth. |

| | Raster to Vector Processing for Road Network Analysis |
| | From that point, vectors are created along the raster path in a continuous chain and displayed on the computer monitor, pausing only for operator input where the preset parameters cannot adequately guide a decision, where paths are uncertain at intersections, or where a feature terminates. | | | The exact process of this editing is dependent upon the software being used and will normally be described in the software documentation. | | | At a line terminus, the algorithm pauses for operator input which consists of selecting another start point for a vector chain or, if collection is complete for a particular section of the network, ending the creation process completely. |

| | Unix: Vector Processing |
| | The reason vector processing allows interaction between the operations is that the operations can be things like "multiply each cell(n) with cell(n*2) and store the result in cell(n*3)", which means that the next instruction gets to see all the new data. | | | The classic example is the Cray 1 computer, which allows a program to load up a bunch of registers with a bunch of math operations and then let them loose. | | | In pipelining, instructions in the pipeline are not complete, so if an instruction tries to operate on a register that's in the process of being changed by another instruction in the pipeline, you'll get indeterminate results. |

| | Because the vector market was so well-established at the high end, there was a lot of code in areas needing large-scale computation, like weather prediction, which could not be rewritten overnight (and in some cases, didn't fit the new computation model too well). | | | A vector computer can do such replicated operations as a single instruction, taking advantage of the fact that it is easy to make a memory that streams data sequentially, than which can access data scattered randomly. | | | A multiprocessor system of this kind uses a very different style of programming to a vector machine: it requires that the instructions be split over multiple processors, whereas a vector machine needs to find a lot of data for the same instruction. |
