Sieve of eratosthenes parallel

WebApr 10, 2024 · I have two ideas on how to parallelize the sieve. n is the number we want to find the primes up to, so what I do is divide the n into segments, where I each thread will get a segment, the threads will now sieve through their segment and store their primes in their local list of primes. In the end when all primes are finnished we will merge the ...

WebOct 29, 2024 · The sieve does not lend itself to being very easily parallel. Your code here is complex, obviously error-prone, difficult to maintain, and performs worse the more threads you throw at it. To top this off, even your best performance seems to be about 10 times slower than a naive single-threaded implementation . how to screenshot samsung galaxy a53 https://jocatling.com
