Coding Problems
Section titled “Coding Problems”Question 1: Parallel Array Sum
Section titled “Question 1: Parallel Array Sum”Q1: Given a large array, compute the sum using parallel processing concepts.
Solution (C++):
#include <vector>#include <thread>#include <numeric>
int parallelSum(vector<int>& arr, int numThreads) { int n = arr.size(); int chunkSize = n / numThreads; vector<thread> threads; vector<int> partialSums(numThreads, 0);
for (int i = 0; i < numThreads; i++) { int start = i * chunkSize; int end = (i == numThreads - 1) ? n : (i + 1) * chunkSize; threads.emplace_back([&, start, end, i]() { partialSums[i] = accumulate(arr.begin() + start, arr.begin() + end, 0); }); }
for (auto& t : threads) t.join(); return accumulate(partialSums.begin(), partialSums.end(), 0);}Time Complexity: O(n/p) where p is number of threads
