How can I ensure that the main child lives till all children finishes
their jobs and get killed?
Is there any way that I can invoke a function when a thread gets killed?

Thread#join?

I don’t understand. Are you looking for #at_exit?

You can remove the question mark. 
A typical idiom looks like this
threads = 10.times.map {|i| Thread.new { … } }
…
threads.each &:join
alternative: collect all results
results = threads.map &:value

That is invoked when the main thread exits but not per thread. Per
thread one can do
Thread.new do
begin
do_work
ensure
printf “Thread dies %p\n”, Thread.current
end
end
But using Thread#join or Thread#value is usually sufficient.
Kind regards
