One might argue that this is still biased against Julia due to its compilation strategy, but fixing that would mean you'd have to figure out what the appropriate way to get 'equivalent' timings for any of the other languages would be as well - something far more involved than just slapping a timer around a block of code in all cases...
edit: As pointed out below, the Julia code should indeed already have been 'warmed up' due to a preceding sanity check. My apologies for 'lying'...
n = length(ARGS) > 0 ? parse(Int, ARGS[1]) : 100
left = calc(101) # <------- THIS IS COLD START JITTING CALL
right = -18.67
if abs(left - right) > 0.1
println(stderr, "$(left) != $(right)")
exit(1)
end
notify("Julia (no BLAS)\t$(getpid())")
t = time()
results = calc(n)
elapsed = time() - t
notify("stop")
