Help me choose my plan

Hi,

First, I knew you thanks to this:

Second, my requirements:

• crunching numbers 24/7

• CPU power, period. No noticeable storage space, bandwidth or particular software (save for one I will provide)

• Ubuntu (command-line, ideally 13.10 or maybe 14.04) and either root access or the possibility to add some software and dependancies I will tell you about.

One thing I have to check if the amount of RAM I need. It may be 256 Mb (or less) or up to 3Gb (but no more). I will only know this by testing.

So, what do you suggest me:

• 24/7 computation

• Ubuntu 13.10 + root or you install some software for me

• flexible amount of RAM at the beginning (for initial testing purposes)

• stripped down of everything else (=> cheaper)

Thank you
