Allocate particular amount of memory to a ruby thread?

how to allocate particular amount of memory to a ruby thread or to a
ruby script?

for example suppose if i want to start a thread it should take 1 MB
memory only

Thread.start(memory=102410241024) do |t|

some stuff here

end

is there anyway to do like this ?

AFAIK, the memory is shared among threads, no matter whether system or
ruby’s.
The memory for the whole ruby process/script is allocated on demand,
with some initial amount.
This amount and growing ratio is compiled-in (at least for 1.8).

Exactly. That’s the whole point of threads.

And there is no way to limit it. It might be possible to limit on a per
process base (depending on OS, see “ulimit -a”) but not on a per thread
base. And there might be a limit on the stack size. But it does not
make sense to limit memory allocated by a thread because the memory is
shared and can be used from any thread.

Kind regards

Pokkai, what’s your primary goal/problem? Why do you want to limit the
memory?
Maybe there’s a solution if you can look at the problem from another
angle.
