WebNov 2, 2024 · 先说明几个概念： 1、Flit: flow control unit 最小流控单位，一个packet可以由一个或多个flits组成 2、Phit: physical unit 物理层传输单位，一个flit可以由一个或多个phits组成，phit定义为两相邻网络设备之间的一次传输 3、虚通道（Virtual channel）：通过时分复用方式共享物理链路。 WebA flit is composed of integral number of phits, where a phit is defined as the number of bits transmitted in one unit interval (UI). For instance, a full-width QPI link transmits and receives a complete flit using four phits. Each flit includes 72 bits of payload and 8 bits of CRC. That means its flit size is 128bits and phit size is 16bits. Also consider the IBM SP2 switch. It also uses the flit level message flow control, but its flit size is equal to its phit size, which is set to 8 bits. Flit width determination. Note that the message size is the dominant deciding factor (among many others) in deciding the flit … See more In computer networking, a flit (flow control unit or flow control digit) is a link-level atomic piece that forms a network packet or stream. The first flit, called the header flit holds information about this packet's route (namely the … See more It is important to note that flits represent logical units of information, while phits represent the physical domain, that is, phits represent the number of bits that can be transferred in … See more A flit (flow control units/digits) is a unit amount of data when the message is transmitting in link-level. The flit can be accepted or … See more The growing need for performance from computing systems drove the industry into the multi-core and many-core arena. In this setup, the execution of a kernel (a program) is split across multiple processors and the computation happens in parallel, thus … See more Consider an example of how packets are transmitted in terms of flits. In this case we have a packet transmitting between A and B in the figure. The packet transmitting process is … See more • Wormhole switching See more iphone app hosting pricing
