WGU C952 Practice Exam With Complete Questions And
Correct Answers| Brand New Version!
Memory Hierarchy - -Answer-: concept that is necessary for the CPU to be able to manipulate data.
Strong scaling - -Answer-: Speed-up achieved on a multiprocessor without increasing the size of the
problem.
Weak scaling - -Answer-: Speed-up achieved on a multiprocessor while increasing the size of the
problem proportionally to the increase in the number of processors.
Not bound by Amdah's Law
multiprocessor architecture - -Answer-: A unified graphics and computing multiprocessor executes
vertex, geometry, and pixel fragment shader programs, and parallel computing programs
advantages:
Increased throughput
Cost saving
Increased reliability
Streaming processor (SP) - -Answer-: the primary thread instruction processor in the multiprocessor
Special function unit (SFU) - -Answer-: Compute 32-bit floating-point approximations to reciprocal,
reciprocal square root, and key transcendental functions. It also implements 32-bit floating-point planar
attribute interpolation for pixel shaders, providing accurate interpolation of attributes such as color,
depth, and texture coordinates.
,Uniform Memory Access (UMA) - -Answer-: A multiprocessor in which latency to any word in main
memory is about the same no matter which processor requests the access.
Non-Uniform Memory Access (NUMA) - -Answer-: Varying system memory access times, because of
system hardware.
throughput - -Answer-: the amount of work performed by a system during a given period of time
CPU Time Formula - -Answer-: (Instructions) x (CPI) x (Clock Cycle Time)
Set Associative Cache - -Answer-: A cache that has a fixed number of locations (at least two) where each
block can be placed
(Block number) modulo (Num set in the cache)
Variable
one-way - Original set
two-way - Will improve overall performance
four-way
eight-way
Fully associative cache - -Answer-: A cache structure in which a block can be placed in any location in the
cache.
CDC 6600 - -Answer-: This system is widely considered to have been the first supercomputer. Also first
load-store architecture
Tomasulo's Algorithm - -Answer-: An algorithm for dynamic scheduling and out-of-order execution
, uses dynamic hazard detection, generalized forwarding, and reservation stations.
IBM 7030 - -Answer-: AKA Stretch
Produced with the goal of being 100 times faster than the previous IBM 704
Imprecise interupt - -Answer-: The unpopularity of imprecise interrupts led to the standard of commit
units in dynamically scheduled pipelined processors
Digital Equipment Corporation (DEC) - -Answer-: A major American company in the computer industry
from the 1950s to the 1990s
PDP-8 - -Answer-: First commercial minicomputer introduced by Digital Equipment Corporation
cost under $20,000
Intel 4004 - -Answer-: First microprocessor
supercomputer - -Answer-: a particularly powerful mainframe computer.
Seymour Cray - -Answer-: American inventor of the Cray supercomputer.
Least Significant Bits - -Answer-: The two bits furthest to the right
most significant bit - -Answer-: left most bit
Sign and magnitude representation - -Answer-: a signed number representation where a single bit is
used to represent the sign and the remaining bits represent the magnitude
