Study Notes
Parallel Computing Concepts
- Embarrassingly parallel computation refers to a type of computation where a problem can be divided into smaller, independent tasks that can be executed simultaneously with minimal communication between tasks.
Multiprocessing Systems
- Shared-memory systems are characterized by multiple processors sharing a common memory space, where all processors can access the same memory.
Multi-Core Processors
- The key feature of multi-core processors is the integration of two or more processing units (cores) on a single chip, increasing processing power and efficiency.
Task Assignment
- Dynamic assignment in parallel computing involves assigning tasks to processors at runtime, whereas static assignment involves assigning tasks to processors at compile time; the key difference is the flexibility in task allocation.
Parallel Computing Acronyms
- SPMD stands for Single Program, Multiple Data, a parallel programming model where multiple processors execute the same program on different data elements.
Speedup in Parallel Computing
- Speedup in parallel computing refers to the improvement in execution time of a program when executed in parallel, compared to sequential execution.
Memory Systems
- Shared-memory systems share a single memory space among multiple processors, providing efficient data sharing and communication between processors.
Parallel Program Design
- Divide and Conquer is a concept in parallel computing where a program is divided into smaller tasks that can be executed simultaneously on different processors, increasing overall processing power.
