I am trying to assemble a matrix using multiple processes. To make sure each process writes to the part of the matrix it owns, I am using a callback as one of the arguments to the single process jobs launched by the driver. function assemble() M = N = 1000 A = zeros(M,N) store = (v,m,n)…

Performance hit when using callbacks

Ah…

Changing the corresponding line to the following fixed it:

start::Int, stop::Int = splits[i]+1, splits[i+1]
