I am using parfeval to run code asynchronously on workers. The running time varies a lot between workers depending on some parameters that in the following code I represent with 'm'.
When I collect the results with fetchNext, I then process them with idx, in particular retrieving m(idx). At the same time, I need to clear the last retrieved FevalFuture object to save memory.
N = 10;
m = 1:10;
for idx = N:-1:1
f(idx) = parfeval(@(m,N) m*rand(N), 1, m(idx), N);
total = 0;
for idx = 1:N
[idx, data] = fetchNext(f);
f(idx) = ;
If you comment the line indicated the code will work fine, but if I clear f(idx) the just-used idx could be reused and I would process the data with the wrong m(idx).
How is it possible to get the correct index idx with which f(idx) was called in the fist loop?
Thanks in advantage
