Parallel Computer Architectures
Two Basic Architectures
Distributed Memory (ex. Compute cluster)
collection of nodes which have multiple cores
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 cores
share a global memory space
cores can efficiently exchange/share data
