The VM's by themselves are just simple OS boxes. To run some tasks on
them you will need a job execution environment. There are plenty of
solutions that could be used for that purpose.
I'm personally looking at using IPython [1] and UNICORE [2] for
accessing the computing resources provided in cloud. There is also an
idea to use QosCosGrid [3] software stack but all this requires
experiments with setups.

We need some way to provision required resources in cloud with specially
prepared VMs. This could be achieved through CloudStack API or with a
help of BOSH [4].

These are just my thoughts on the subject.

See how Amazon provides HPC resources [5, 6]
