As dsicussed, you could use Amazon EC2, or ask at your college for
access to a Condor pool.

Another alternative would be to build your own cluster.
You would not need to buy new machines - though if you did have the
budget, all you would need is motherboards, and just stakc them up
caseless and link them with a switch.

I should ask though - what language are you using?
Is it something which is amenable to running on a GPU? I ask as
Portland have recently announced compiler directives for GPUs,
and as a student you should be able to get a cheap or free license:
