翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Gather-scatter (vector addressing) ： ウィキペディア英語版 Gather-scatter (vector addressing) Gather-scatter is a type of memory addressing that often arises when addressing vectors in sparse linear algebra operations. It is the vector-equivalent of register indirect addressing, with gather involving indexed reads and scatter indexed writes. Vector processors have hardware support for gather-scatter operations, providing instructions such as ''Load Vector Indexed'' for gather and ''Store Vector Indexed'' for scatter. ==Definition== Denoting by $idx$ the list of indices of sparse vector $x$, the sparse gather of dense $y$ into $x$ denoted $x\; \backslash leftarrow\; y|\_x$, assigns $x(i)=y(idx(i))$.〔(BLAS Technical Forum standard, Chapter 3: Sparse BLAS. )〕 The sparse scatter, denoted $y|\_x\; \backslash leftarrow\; x$ is the reverse operation. It copies the nonzero values of sparse $x$ into the corresponding locations in the dense vector $y$, i.e. $y(idx(i))=x(i)$. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Gather-scatter (vector addressing)」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
