OpenCAPI Memory Interface (OMI) is a serial attached RAM technology based on OpenCAPI, providing low latency, high bandwidth connection for main memory. OMI uses a controller chip on the memory modules that allows for technology agnostic approach to what is used on the modules, be it DDR4, DDR5, HBM or storage class non-volatile RAM. An OMI ...
UPI is a low-latency coherent interconnect for scalable multiprocessor systems with a shared address space. It uses a directory-based home snoop coherency protocol with a transfer speed of up to 10.4 GT/s. Supporting processors typically have two or three UPI links.
The earliest academic publication of trace cache was "Trace Cache: a Low Latency Approach to High Bandwidth Instruction Fetching". [1] This widely acknowledged paper was presented by Eric Rotenberg, Steve Bennett, and Jim Smith at 1996 International Symposium on Microarchitecture (MICRO) conference.
The current specification HTX 3.1 remained competitive for 2014 high-speed (2666 and 3200 MT/s or about 10.4 GB/s and 12.8 GB/s) DDR4 RAM and slower (around 1 GB/s similar to high end PCIe SSDs ULLtraDIMM flash RAM) technology [clarification needed] —a wider range of RAM speeds on a common CPU bus than any Intel front-side bus. Intel ...
InfiniBand (IB) is a computer networking communications standard used in high-performance computing that features very high throughput and very low latency. It is used for data interconnect both among and within computers.
For example, the 8 node butterfly network can be split into two by cutting 4 links that crisscross across the middle. Thus bisection bandwidth of this particular system is 4. It is a representative measure of the bandwidth bottleneck which restricts overall communication. Diameter: The worst case latency (between two nodes) possible in the ...
According to the New York Times, here's exactly how to play Strands: Find theme words to fill the board. Theme words stay highlighted in blue when found.
High Bandwidth Memory (HBM) is a computer memory interface for 3D-stacked synchronous dynamic random-access memory (SDRAM) initially from Samsung, AMD and SK Hynix.It is used in conjunction with high-performance graphics accelerators, network devices, high-performance datacenter AI ASICs, as on-package cache in CPUs [1] and on-package RAM in upcoming CPUs, and FPGAs and in some supercomputers ...
