WGU D001 TEST SCRIPT 2026 QUESTIONS
WITH SOLUTIONS GRADED A+
⩥ 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
