Coarse-grained systems consist of fewer, larger components than fine-grained systems; a coarse-grained description of a system regards large subcomponents while a fine-grained description regards smaller components of which the larger ones are composed.
Which is stronger fine grain or coarse grain?
A fine grained metal contains a large number of grains. A coarse grained metal contains fewer grains. A fine grained metal is therefore stronger than a coarse grained metal . Sometimes, grain refining agents are added to the molten metal before it is cast to provide nuclei around which grains can grow.
What is the difference between fine and coarse grained?
Coarse-grained materials or systems have fewer, larger discrete components than fine-grained materials or systems. A coarse-grained description of a system regards large subcomponents. A fine-grained description regards smaller components of which the larger ones are composed.
What is the difference between coarse grained and fine grained multithreading?
The main difference between Fine Grained and Coarse Grained Multithreading is that, in fine grained multithreading, the threads issue instructions in round robin manner while in coarse grained multithreading, the threads issue instructions until a stall occurs.
What is meant by coarse grains?
Coarse grains generally refers to cereal grains other than wheat and rice — in the OECD countries, those used primarily for animal feed or brewing . Context: ... In Mexico, most maize is produced for human consumption rather than animal feed.
What is a fine grained service?
Fine-grained – smaller components of which the larger ones are composed , lowerlevel service.
What is called as fine grained multithreading?
Definition. Fine grained multithreading is a multithreading mechanism in which switching among threads happens despite the cache miss caused by the thread instruction.
Does increasing grain size increase ductility?
Grain boundaries are known for dislocation-anchoring, which lowers ductility. Finer grains also mean there are more grain boundaries. The greater the number of grain boundaries, the greater the tonnage is required to bend the metal. ... At the same time, a grain boundary that is finer is known to raise ductility .
Does grain size affect hardness?
As seen in Fig. 3, the hardness decreases monotonically with increasing indentation depth for a grain size of 80 μm which is considered a large grain. However, for smaller grain sizes, hardness increases with increasing indentation depth at a specific range.
How does grain size affect material properties?
Grain size has a measurable effect on most mechanical properties . ... Also, fine-grain steels have greater fatigue resistance, and a fine grain size promotes a somewhat greater toughness and shock resistance. Steels made fine grained by addition of aluminum have machinability inferior to those made without aluminum.
What is very fine level parallelism?
In fine-grained parallelism, a program is broken down to a large number of small tasks . These tasks are assigned individually to many processors. The amount of work associated with a parallel task is low and the work is evenly distributed among the processors. Hence, fine-grained parallelism facilitates load balancing.
What is coarse grained access control?
Role-based solutions are considered coarse-grained because they organize users into ‘roles’ and grant or deny access rights based only on these roles, while ignoring other factors.
Does multiprocessing allows single processor to run several concurrent threads?
Multiprocessing allows single processor to run several concurrent threads. Explanation: The statement is false. Multitasking allows single processor to run several concurrent threads. Explanation: A thread is a sequential flow of control within a program.
What are coarse grains examples?
Coarse cereals include maize (Zea mays), sorghum (Jowar; Sorghum vulgare), oats (Jai; Avena sativa) , barley (Jow; Hordeum vulgare), pearl millet (Bajra; Pennisetum glaucum) and other minor millets such as Finger millet (Ragi; Eleusine coracana), Kodo millet (Arikalu; Paspalum setaceum), Proso millet (Cheena; Penicum ...
Why are coarse grains important?
1. These grains require very less amount of water and can be grown in water deficit areas. 2. These grains are a very good source of essential nutrients and hence can be used in animal feed.
What are coarse grains called?
Jowar, Bajra, Ragi, Maize etc. are examples of coarse grains. These crops are High in calorific & Nutritional value. These are majorly used for feeding the animals and aren’t categorized as premium grains (which excludes wheat and rice).
