Would it be possible, in windows 7 to parellel-ify the system, (run on many nodes at the same time for hugely increased performance) and would it be easy?

No. Windows 7 is designed to run better in multi-core system comparing to its predecessor (i.e. Windows Vista).

If you want some multi-node OS, you should try some special linux distribution specially built for this kind of usage.

Any reccomendations? –  Joe Oct 23 '09 at 10:24

How about Rocks Cluster? It is, quote "open-source Linux cluster distribution that enables end users to easily build computational clusters" rocksclusters.org/wordpress/?page_id=57 –  deddebme Oct 23 '09 at 16:00

No.

The OS has its own methods for parallelizing O.S. operations, but not individual application performance. It is up to the individual applications to do any further multi-threading optimization (parallelizing). Modern OS's handle a lot of parallelizing currently as multiple core processors are now found in most modern computers, which require parallelization to be fully utilized/optimized.

As for making many nodes work together (Cluster), that is not a Windows 7 feature found on the consumer versions of Windows. Windows server machines have this capability for distributing network managment traffic, but not for individual client applications.

EDIT: Some links and parallel project:

http://www.lam-mpi.org/ LAM/MPI Parallel Computing - This is the LAM version of the MPI interface. I have used this before and it works well. Should install under most linux installations. I used this one with Ubuntu server 7.10. http://www.ubuntu.com/products/whatIsubuntu/serveredition

If you don't know what MPI is: http://www.mcs.anl.gov/research/projects/mpi/

Note: For this to work properly, the application needs to be adapted to the MPI interface or be built specificly for this environment.
