Distributed Shared Memory Architecture (DSM)

• Local memory and independent path to memory as with the Multicomputer Architecture
• Memory of all nodes is organized as one logical “shared memory”
• Non-uniform memory access (NUMA):
  • “Local memory” access is faster than “remote memory” access
• Programming model is (almost) the same as for the Shared Memory Architecture
  • data distribution is available for optimization
• Scalability properties similar to the Multicomputer Architecture
