Hello, 
I have a very large data processing task and I need to rent processing
time on powerful servers, but I have been unable to find companies
that provide this service. Specifically, I need:
(1) to rent access to linux based servers to process my own data
(2) I do not want the servers delivered to me - I want the company I
am renting from to host the servers and allow me to access them via
the web
(3) I need the servers to be dedicated to me for the time I rent them
- I do not want to share them with other users
(4) I need a short term rental of the servers - about 1 month
(5) I need to rent between 4 and 10 servers, depending on how powerful
the servers are (e.g., I will need fewer quad processor servers than
single processor servers)
(6) I could also rent a supercomputer for a short time, so please
include these if you find them

Could you provide me with a thorough list of companies that provide
this service? Also, please include information on cost, as well as the
type of servers that the company rents (e.g., processor specs, drive
space, ram, etc). Please exclude any company that cannot meet my
criteria above.

Thanks, 
Charles
