python - build an instance with 100 cpus and 54G of ram -

So I'm playing with Datatrix and Amazon's Hood and I think they are both amazing technologies.

I have potentially a question, for example, why can not I create examples of 100 CPUs and 54G RAM, for example, to fill my matrix, I have a huge data process And shared memory is required i am using python and parallel python modules ... so i have parallel processing in code i need a forum with so many cores i The Jud?

Many thanks
