Hi all, I swear I tried to look into the documentation or online but I can't figure out what I want to do. I have a lot of sequential code executed and at some point I want to parallelize the following loop:
mat_a = zeros(n, n) for i = 1:n mat_a[i,i:n] = mean(mat_b[:,i] .* mat_b[:,i:n], 1) end with mat_b being computed before. I have a bunch of questions in order to better understand things: - how to best choose the number of procs with which I run julia? - since each operation on the rows of mat_a can be done independently from the others, I'd like to send mat_b to each worker so that it can compute certain lines of the matrix mat_a in the form of an array of vector which I would concatenate afterwards to retrieve mat_a. I wanted to send mat_b with the @everywhere macro but it seems this works only for definitions of variables directly on a worker. I don't know how to send already computed data to a specific worker. - more generally, is this the best approach to parallelizing this kind of code? Any advice appreciated, Thanks a lot,
