CHAPTER 17 - SHORT ANSWER
Computer systems that fall into the __________ category have a single processor that executes a single instruction stream to operate on data stored in a single memory.
Computer systems that fall into the _________ category have a single machine instruction that controls the simultaneous execution of a number of processing elements on a lockstep basis.
Computer systems that fall into the __________ category have a sequence of data that is transmitted to a set of processors, each of which executes a different instruction sequence.
Computer systems that fall into the ________ category have a set of processors that simultaneously execute different instruction sequences on different data sets.
A ________ is a group of interconnected, whole computers working together as a unified computing resource that can create the illusion of being one machine.
The __________ is the simplest mechanism for constructing a multiprocessor system.
______ protocols distribute the responsibility for maintaining cache coherence among all of the cache controllers in a multiprocessor.
The four states of the MESI protocol are: modified, shared, invalid, and ______.
An approach that allows for a high degree of instruction-level parallelism without increasing circuit complexity or power consumption is called ________.
Two key characteristics of a process are: scheduling/execution and ________.
The four principal approaches to multithreading are: interleaved (fine-grained), blocked (coarse-grained), simultaneous, and ________.
_________ is the easiest multithreading approach to implement.
Widely used in data centers to save space and improve system management, a _________ is a server architecture that houses multiple server modules in a single chassis.
An approach where all processors have access to all parts of main memory using loads and stores, with the memory access time of a processor differing depending on which region of main memory is accessed, is _________.
The four deployment models defined by NIST are: public cloud, private cloud, community cloud, and __________ cloud.
Explanation / Answer
Ans:
1)SISD(single instruction single data stream)
2)SIMD(sinle instruction multiple data stream)
3)MISD(multiple instruction single data stream)
4)MIMD(multiple instruction multiple data)
5)"Clusters" is a group of interconnected computers and each computer present in a cluster is called a 'node'.
6)"Time-shared bus" is the simplest mechanism to construct multiprocessor system it consist of data,address and control lines.
7)"Snoopy protocols" are responsible for distributing responsibility of maintaining cache coherence among cache controllers in multiprocessor system.
8)"E" stands for "Exclusive" which is the 4th state of MESI protocols.
9)"Threads" allows high degree of ILP which are also part of a process.
10)4th way of multichreading is Chip multiprocessing.
11)"Resource ownership" is the second characteristic of process
12)"Coarse grained" is the simplest and easiest approach
13)"Blade server" is a server architecture that houses multiple server modules in a single chasis
14)Non uniform memory access(NUMA) is the required approach but here different process access diferent regions of memory at different speeds.
15)"Hybrid cloud" is the 4th deployment model of NIST.
