Which of the following best describes a SIMD architecture?

You are given the following OpenMP program, which approximates π using a parallel loop with reduction:   #include #include #include using namespace std; const int N = 100000000; int main() { int k; const int NUM_THREADS = 4; omp_set_num_threads(NUM_THREADS); double sum = 0.0; #pragma omp parallel for reduction(+:sum) private(k) for (k = 0; k

Consider the following code: A = compute_A();B = compute_B();C = compute_C();D = compute_D(); Explain why this pattern is task-parallel and not data-parallel.  

Indicate whether each statement is true or false based on the graph below. 1) Male reproductive success is limited by access to mates. [1] 2) Males invest more in gametes and parental care. [2] 3) Males are the competing sex and likely use strategies like mating plugs. [3]  4) Males maximize fitness by mating with a few high-quality females. [4]

Explain why load imbalance reduces parallel performance. Provide an example and describe how to mitigate it.

Give an example of a code pattern that results in poor cache locality. Then explain how a small change in data layout or loop order dramatically improves performance.

Differentiate task-based and data-based parallelism. Give a real scientific workload example for each.

Which of the following is true about over the counter (OTC) drug use?

We analyzed data from a meta-analysis on the presence of science-stereotypes in children’s drawings. The authors described which databases of published research they searched, which search phrases were used, and which criteria were used to determine which publications should be included or excluded in their analyses. This process is meant to address _____.

Use the data in the table, which shows the character states for five different traits for in five different species, to answer the following question.    Trait: Species X Species Q Species R Species W Species Y Coat Color brown brown gray brown – Ear Length short short long medium – Tail Length long long long long – Snout Length long short medium extra long – Wings yes yes yes yes yes
