I need to have multiple threads write values to a shared array. I’m thinking of having each thread write to a private array, and then have the threads each write their private values into a shared array. In the following example I’ve chosen values that assume 2 threads, and I’m assuming thread 1 has…

Just playing around with your idea I came up with the following: using .Threads function copyVerts!(b, sub, start) for i in 1:length(sub) b[start + i - 1] = sub[i] end end s1 = 1:nthreads() s2 = s1 .+ 1 c1 = cumsum(s1) c2 = cumsum(s2) sa = [c1[i]:c2[i] for i in s1] b = zeros(Int,m…

Thanks! It looks basically the same as mine, although I think your copyVerts function is better than mine since you’re taking out reference to the thread index, so you don’t have my indirect indexing (b[start[id]+i]). I used an array of subarrays since I don’t know how long each subarray will be and…

If the code were to continue past the for loop, how can one wait until all the spawned tasks have completed? @sync.

the @sync does this.
