Versateam Process Level Cluster.
		-The Inspiration behind the cluster. 
		-Self Imposed Constraints.
		-Classification of the cluster.
		
	What does the cluster offer ?
		-Scope for Parallel Programming.
		-Automatic Load Balancing.
	
	Structure of the Cluster:-
	
		-Inter-Node-Communication Mechanism.
		-Distributed Scheduling Algorithm.
		-Process Migration Module.
		-Module to Enable Load Negotiation.
		-Shared Memory.
		-IPC,Distributed Semaphore Implementation,MPIs.
	
	Inter-Node-Communication Mechanism
		-New Efficient Protocol Stack.
			Physical|Data Link Layer|Physical
		-Two internal Kernel interfaces
			Local Messages.
			Broadcast Messages.
		-External /proc interface to be used by application.
	
	Distributed Scheduling Algorithm 

		-External Distributed Algorithms,that works independent 
				of local scheduling.
		-Selects Process based on fixed policies.
		-Limitations ?

	Process Migration Module
	        
		-Checkpointing Process
		-Library Negotiation.
		-Transfer.
		-Installation back into the memory page.
		-Restart.

	Shared Memory
	
		-Shared Memory, Snooper Cache.
		-Conditions to satisfy.
			Write Serialization,Write Propagation
			Cache Consistency.
		-Solution
	
	IPC/Semaphore/APIs
		-Distributed Semaphore Implementation.
