need your help/ views for distributed programming with ruby

hi all,
greetings,
     I have came across a situation where I want to send sms (Text
Messages) and mails at a time to thousand's/lac's of users. The text may
be a security or traffic alerts so its needed that this should be sent
at a time so that the users may be able to receive them and make some
actions on it.
     The process I am following is to fetch 100 records and send them
sequentially, to fetch record, communicate with sms gateway, get
delivery report and save the sms status as sent in database takes near
about a second.
     I want to make this process as fast as to send the sms /mails at
time thr the distributed programming, COULD YOU PLEASE HELP ME BY
REPLYING WITH YOUR VIEWS OR IDEAS OR IF YOU HAVE CODED SAME, THEN
SHARING SOME OF THE CODE FOR ME?
Thanks In Advance
