Windows Vista Computer Cluster?


New Member
Hey guys,
About a year ago, I started looking at making a Beowulf computer cluster. I've gathered a few old computers(not the same kind) and I had planned to make a cluster out of them.
That never happened. Now that I have a little free time, I was hoping to get it started back up, but I ran into another problem.
It would be useless to me at this point unless I could make use of the cluster's resources from my main computer (without making ANY OS changes), which is running Windows Vista. (Soon to be Win7)
I was wondering if anyone knew if this was possible, or how to do it, because my previous searching has failed me.
Thanks in advance.
