I/O bound computing clusters
I want to build a computing cluster and have been looking into grid solutions. My understanding from grid solutions is that participating nodes have to actually sign up to participate in a computation and that an isolated piece of work is sent to the node through a request from that node (pull). Along that reasoning, would a solution whereby a controlling machine sends work to whichever node is available not be a grid solution (push)?
The problem we will be solving is data-intensive, so we will be looking at an I/O bound problem. What methodology is used whereby the data sits on one machine and the nodes use that data? Could a partitioning of the database work, whereby a node only works on the data in the partition and no other?
