Chris,
Have you tried `for cpu in (0..processorcount.to_i)` ? I'm wondering if
it's possible `processorcount` is a String. You might want to try using
`<%= processorcount.inspect %>` to verify.
BTW, other, more conventional options for doing this type of loop in Ruby
would be:
<% processorcount.to_i.times do |cpu| %>
<% end %>
or
<% 0.upto(processorcount.to_i - 1) do |cpu| %>
<% end %>
Cheers,
Bruce
