cluster machines is having so many nodes. it is having smp,mpp. SMP is symmetric multi processors it having some nodes

smp: symterric multi processing smp:all processors will be using same memory disk,memory buffers.here processcors will be waiting for disk i/o process.

mpp: massively papallel processing.)here each processor will be having it's own memory and mamory devices,phyisically all this processors will embedded in a single cabin.and will communicate through shared memory buses. cluster m/c: same as mpp ,but physically this m/c are housed in different cabins and will communicate through high speed networks.
