Hey there! So I am currently trying to understand how parallelization works in Julia, as a practice I tried writing this nice pi estimator: function estimate_pi(number) m=0. for i=1:number x=rand() y=rand() if x^2+y^2 < 1 m+=1 end end pi …

Try to keep stuff in registers instead of committing to memory! I.e. function count_pi(number) m=0. for i=1:number x=rand() y=rand() if x^2+y^2 < 1 m+=1 end end return m end function estimate_pi_parallel(number) m = zeros(10) …

Individual threads superfast, while sync really slow with virtually no communication

General Usage Performance

Thanks for that answer. But I tried it without SharedArray before and that was also not better
