AMD Dual Core and Ruby

Hi,

does the ruby interpreter use both cores automagically or do I have
to do/program something special ?

Kind regards,
mcc

The ruby interpreter isn’t multithreaded, so it won’t take advantage of
SMP sytems.

The interpreter doesn’t support multithreading itself, so all
ruby-scripts will only use 1 Core, even when they create ruby-threads.
But maybe you can use more than 1 process (e.g. call “fork” instead
creating a thread). Your OS will (hopefully) schedule the second
interpreter on the second core.

best regards,
Matthias

Actually, most second cores on desktop machines (and Windows servers)
are already too busy processing all your spam and viruses. :wink:

You have to do something special.

check out the slave package from Ara T. Howard:

If you are running JRuby, all threads are native threads, and it will
use as
many cores as you have available.
