Hi all,
I finished porting my model to clojure, and am now trying to get it
to run concurrently. During the porting I already to care to wrap
the main functions (birth [loc], death [loc] etc) in dosyncs, and all
the slots in the world-vector are refs.
I've the feeling those are all fine, and I am doing something wrong
in starting the whole machinery. In the below code, I (hope that I)
am sending off a list of instructions to each position in the world
in such a way that the instructions can be processed concurrently.
However, it seems like dotimes is waiting for the send-off agent to
have finished before sending off another one. I think I know this
because when I introduce side-effects (println) into the birth, death
etc functions, the side-effects are fully in order both on the popsize
level and within an agent.
Can anyone tell me what mistake I am making?
(time
(do
(dotimes i popsize
(send-off (agent i)
(doseq a [birth death infect infect evolve
evolve evolve evolve evolve] (a i))))
(println "We've send off the whole population")
(dosync (commute year inc))))
-> output of the model.
