Study Notes
Parallel Random Access Machine (PRAM)
- The PRAM is intended to model algorithmic performance after an idealized parallel machine.
- The PRAM model neglects synchronization and communication delays between processors in order to provide any number of processors.
- It is used by parallel-algorithm designers to model algorithmic performance.
Sequential Algorithm Design
- Sequential-algorithm designers use the RAM (Random Access Machine) model to model algorithmic performance.
Algorithmic Performance Estimation
- Algorithmic performance is estimated using parameters O(time) and O(time × processor_n), which represent the time complexity and processor complexity respectively.
