Is there any service that can i use or rent supercomputer for an hour or two? I would like to use an supercomputer to run my big data project to test it speed. I google the service &amp; see that only this is available for free but it closed last year? Could anybody with experience in using supercomputer know to get access to this kind of hardware?
The answer will depend on where you are, who your funding is from, and what you mean by "a supercomputer".

Various countries, research councils, etc., let you apply for computer time if you are eligible. Some universities have their own in-house systems too.

But also, the major cloud providers - Amazon, Microsoft, Google (?) - will let you rent computing resources. This may be suitable for your needs.
