I have to process a text file that can be up to 10Tb in size, the data 
is only ascii, so I can not see the point for a larger sized CPU. Once a 
  string is found, all it needs to do is hand the string up to the next 
CPU for serving.

This is not a joke Guys, I have someone who is paying me to design this 
system, and speed is essential, so it has to be held in Ram. I do not 
plan to have one CPU to search the whole 10Tb I was planing on using 100 
parallel CPU's each looking after 100Gb of ram.
