Hyper-threading. Hyper-threading (officially called Hyper-Threading Technology or HT Technology and abbreviated as HTT or HT) is Intel 's proprietary simultaneous multithreading (SMT) implementation used to improve parallelization of computations (doing multiple tasks at once) performed on x86 microprocessors.
Simultaneous multithreading (SMT) is one of the two main implementations of multithreading, the other form being temporal multithreading (also known as super-threading). In temporal multithreading, only one thread of instructions can execute in any given pipeline stage at a time. In simultaneous multithreading, instructions from more than one ...
HyperTransport (HT), formerly known as Lightning Data Transport, is a technology for interconnection of computer processors. It is a bidirectional serial / parallel high- bandwidth, low- latency point-to-point link that was introduced on April 2, 2001. [1] The HyperTransport Consortium is in charge of promoting and developing HyperTransport ...
After joining the FreeBSD Security Team in 2004, Percival analyzed the behaviour of hyper-threading as then implemented on Intel's Pentium 4 CPUs.He discovered a security flaw that would allow a malicious thread to use a timing-based side-channel attack to steal secret data from another thread executing on the same processor core and sharing its cache.
Multithreading (computer architecture) For threads in software, see Thread (computing). A process with two threads of execution, running on a single processor. In computer architecture, multithreading is the ability of a central processing unit (CPU) (or a single core in a multi-core processor) to provide multiple threads of execution.
Hyperloop is a proposed high-speed transportation system for both passengers and freight. [ 1 ] The concept was published by Elon Musk in a 2013 white paper, where the hyperloop was described as a transportation system using capsules supported by an air-bearing surface within a low-pressure tube. [ 2 ] Hyperloop systems have three essential ...
Simultaneous multithreading (of which Intel's Hyper-Threading is the best known) was an early form of pseudo-multi-coreism. A processor capable of concurrent multithreading includes multiple execution units in the same processing unit—that is it has a superscalar architecture—and can issue multiple instructions per clock cycle from multiple ...
Introduction. Micro-threading is a software-based threading framework that creates small threads inside multi-core or many-core processors. Each core may have two or more tiny threads that utilize its idle time. It is like hyper-threading invented by Intel or the general multi-threading architecture in modern micro-processors.
