Study Notes
Modern Supercomputers
- Modern supercomputers are shared-/distributed-memory hybrids
- They combine the advantages of shared-memory and distributed-memory architectures
Shared-Memory Parallel Computers
- Shared-memory parallel computers have a single address space for all processors/cores
- They are cache coherent, meaning changes in one cache are communicated to all others for consistency
CPU Shared Memory
- Two basic variants of CPU shared memory: UMA (Uniform Memory Access) and ccNUMA (cache-coherent Non-Uniform Memory Access)
- UMA:
- All memory is accessible by all cores with equal latency and bandwidth
- No distinction between local and remote memory
- ccNUMA:
- Latency and bandwidth vary depending on the mutual position of core and memory
- Provides better performance and scalability than UMA
Why ccNUMA?
- ccNUMA is preferred over UMA due to its ability to handle larger and more complex systems
- It provides better performance and scalability by minimizing memory access latency and bandwidth variation
