(2) Parallel Computer Architectures
Parallel Computer Architectures
Two Basic Architectures
Distributed Memory (ex. Compute cluster)
collection of computers which may be dual or quad-core nodes
each node uses its own local memory
work together to solve a problem
communicate between nodes and cores via messages
nodes are networked together
Shared Memory Computer
multiple processors
share a global memory space
processors can efficiently exchange/share data
Latest Parallel Computers mixed shared/distributed memory architecture
nodes have more than 1 processor
dual/quad-core processors
