hi,
I am trying test parfor speedup using my code:
parfor n=1:100
npix{n}=zeros(1,10000);
projection{n}=cell(1,10000);
for m=1:10000
[npix{n}(m),projection{n}{m}]=test(PSys,PDet,PAttMap);
end
end
%%%%%%%%%%%%%%%%%
but the speedup is not very good. I think that maybe it is due to the large data to tranfer, because varible, PSys, PDet are very larger array. I wonder how the data is tranfered? are those variable tranfered from client to nodes each time when they are used, or they are copied to nodes only one time for the parloop?
Thank you very much.
Michael
