WeboT this end, we propose the Gather-Scatter DRAM ( GS-DRAM ), a substrate that allows the memory con-troller to gather or scatter data with strided access pat-terns (speci cally power-of-2 strides) e ciently. Our ob-servation is the following. Modern DRAM modules con-sist of multiple chips.

Gather operators fetch data at the indexed locations and provide this as the output, while scatter operators usually update the output data at the indexed locations.

WebJan 4, 2011 · Gather/Scatter are sorely missed from the ISA for many purposes. AVX not having FMA as promised initially is a disappointment I can live with. However, AVX not having integer operations is detrimental for its adoption by developers including me. Integer operations would greatly benefit video coding/decoding and other media applications.

WebBuild Scatter Gather List Calls/sec is the average rate, in incidents per second, at which NDIS received a request from an interface to build a scatter gather DMA list. Build Scatter Gather List Calls/sec 是 NDIS 从构建 分散 收集 DMA 列表的接口接收请求的平均速率，单位为每秒事件数。 In computing, vectored I/O, also known as scatter/gather I/O, is a method of input and output by which a single procedure call sequentially reads data from multiple buffers and writes it to a single data stream, or reads data from a data stream and writes it to multiple buffers, as defined in a vector of buffers. Scatter/gather refers to the process of gathering data from, or scattering data into, the given set of buffers. Vectored I/O can operate synchronously or asynchronously. The …

Gather/scatter is a type of memory addressing that at once collects (gathers) from, or stores (scatters) data to, multiple, arbitrary indices. Examples of its use include sparse linear algebra operations, sorting algorithms, fast Fourier transforms, and some computational graph theory problems. It is the vector … See more x86-64 CPUs which support the AVX2 instruction set can gather 32-bit and 64-bit elements with memory offsets from a base address.
