I'm wondering how to save data/results in a parallel for-loop. Let's assume there is a single Int64 array, initialised using zeros() before starting the for-loop. In the for-loop (typically ~100,000 iterations, that's the reason I'm interested in parallel processing) the entries of this Int64 array should be increased (based on the results of an algorithm that's invoked in the for-loop).
Everything works fine when using just a single proc, but I'm not sure how to modify the code such that, when using e.g. addprocs(4), the data/results stored in the Int64 array can be processed once the for-loop ends. The algorithm (a separate function) is available to all procs (using the require() function). Just using the Int64 array in the for-loop (using @parallel for k=1:100000) does not work as each proc receives its own copy, so after the for-loop it contains just zeros (as illustrated in a set of slides on the Julia language). I guess it involves @spawn and fetch() and/or pmap(). Any suggestions or examples would be much appreciated :).
