How long is a piece of string?
The time it takes to crack a password with a 'supercomputer' depends on two things- the strength of the password, the length and of course what you define as a supercomputer.
Password cracking falls into two categories- wordlists and brute force.
Wordlists look at common words- like love, hate, sexy, girl, 69, and other common words people for some reason like to use in passwords.
Wordlists can quickly crack easy passwords in say less than a day assuming the user has used a fairly common phrase.
If the password is tricky, then brute force must be used. It basically 'guesses' character by character until the lock clicks.
If your password has one character, assuming its english, then there are 26 possibilities. Any computer made in the last say 20 years could probably work that out in a second to a minute.
All it has to do is try every letter...
Add another character (two character password) and it gets tricker- there's now 26 possibilities x 26 possibilities= 676 possibilities. A modern computer could still solve that in less than a minute.
3 character password= 177788 possibilities.
A modern computer could probably solve in less than an hour.
4 character password= 46222488 possibillities.
A modern computer should be able to solve in a few weeks...
5 characters?
A modern computer should be able to solve in a year?...
6 characters?
A modern computer could take many years... This is where a super computer might be needed.
Get enough super- computers together, to distribute the load and you could have it in a matter of seconds. Most supercomputers will consist of an array of interconnected computers, these computers might have quad core processors and then several GPU (graphics processors) which can also take on part of the load.
It's all about splitting the guesses up.
As supercomputer power becomes the norm in 'personal computers' the need for other means of security (fingerprint scanners, retina scanners, face recognition) will become necessary.
Because even a clever 8 character may not be strong enough in say 10 years, for a PC (with the strength of what we consider a massive super computer now) might be able to crack it in a matter of seconds).

Which computer is super fast computer in 2014?
In June 2014 the world's fastest supercomputer was Tianhe-2, a supercomputer developed by China's National University of Defense Technology. This checked out at 33.86 Pflop/s (quadrillions of calculations per second) on the Linpack benchmark.
How can password help in data security?
If it is a good password, then it can help a great deal. Depending on the length and complexity of the password, it can take an attacker months, if not years on a super computer to crack a challenging password. There is no such thing as a completely secure system, but having a good password can certainly stall an attack for some time.
What is a complex password?
A complex password - is one of at least 10 digits - comprising a random set of letters and numbers. For example instead of using 'python1962' (a simple password), you could use p1y9th6o2n. Complex passwords are much more difficult (a) to remember and (b) to crack.
What is the storage for supercomputer?
A "supercomputer" is simply a large computer, that works very fast (much faster than the average home computer). There are many of them, so it is doubtful whether they all use the same type of storage. Computers usually use hard drives to store data; other options include flash storage, and RAM.
What is another name for supercomputer?

A mainframe computer is the fastest type of computer?
They are fast, but a supercomputer is faster.
Would IE run fast on a supercomputer?
Of course not. It's IE.
Can a supercomputer simply be a massive collection of networked computers?
No - a supercomputer is a single device or system (although fast and expensive). A massive collection of networked computers can give the results of a supercomputer but they would not be considered one.
