Elixir distributed programming - measuring scalability

Hi guys.

I want to test scalability of Elixir. I have 2-3 computers in one network and I want to run same program in these computers and measure scalability. (I also need some load balancer right ?)

e.g.:
One computer make “test” in 60 seconds, but if I add another pc, it will take only 35sec, with 3 computers it will take only 25sec)
or
One computer can “make” 1000 calculation in one minute. Two computer can make 1800 calculation in one minute.

Can somebody write some readme me to this ? Or, is something on web ?

thanks
