;; This is the simulation setup for commcheck1.scm.  See the 
;; HLSIM documentation for further details.

(load-option 'hlsim)

;; If you are using this example for the very first time, you need some
;; compiled files available to load.  If you do not have these, you can 
;; generate them with the following:

(cf "club5d") ; normal compilation (scm -> bin -> com), generates club5d.com

(cps "commcheck1") ;  gunk compilation (scm -> bin), generates neighbors1.bin
(cbf "commcheck1") ;  gunk compilation (bin -> com), generates neighbors1.com

;; If you have the compiled files, start from here

(load "club5d")

;; Make the simulation

(set! *store-size* 30)

;; Go from here to run different simulations.

;; The mean neighborhood density is just under n * pi * r^2
;; e.g. for a quick simulation try 1000 procs, radius 0.04, n pi r^2 = 5.0

(define sim (make-sim/1 1000 0.04))

;; e.g. for a large simulation try 10000 procs, radius 0.012, n pi r^2 = 4.5
; (define sim (make-sim/1 10000 0.012))

(simulation.display! sim #T)

(simulation.load sim 'init "commcheck1")

(simulation.run sim)

;; get some stats on simulation

(define (stats sim exp)
  (let ((l (list-transform-positive 
	       (vector->list (simulation.eval sim exp))
	       number?)))
    (list exp
	  (apply min l) 
	  (round (/ (apply + l) (length l)))
	  (apply max l))))

(stats sim 'collisions)
(stats sim 'receives)
(stats sim 'end-time)
