Implicit Parallelism

Spread this useful information with your friends if you liked.

1. Implicit parallelism is a type of parallelism that occurs automatically, without explicit instruction or control from the programmer.

2. It is hidden or “implicit” in the code itself, and is automatically exploited by the computer system.

3. There are several types of implicit parallelism, including instruction-level parallelism, thread-level parallelism, and data parallelism.

4. Instruction-level parallelism occurs when multiple instructions can be executed simultaneously or in a pipeline.

5. Thread-level parallelism occurs when multiple threads of execution can be created and run concurrently, such as in a multi-threaded program.

6. Data parallelism occurs when a single instruction operates on multiple data items simultaneously, such as in vector operations or matrix multiplication.

7. Implicit parallelism can be exploited by modern processors and computer systems to improve performance and efficiency.

8. However, it can also be challenging to program for and optimize, as the parallelism is not always visible or easy to control.

9. Implicit parallelism is often contrasted with explicit parallelism, which involves explicitly instructing the computer system to execute multiple tasks or operations in parallel.
