OpenMP: parallel regions and loop parallelism

Loop parallelism

• Very common type of parallelism in scientific code

• In previous trapezoid example, we calculate the division of iteration manually.

• An alternative is to use parallel for pragma

Hands-on 1: Sum series implementation

• In the EXPLORER window, right-click on openmp and select New File.

• Type sum_series_for.c as the file name and hits Enter.

Hands-on 2: Improving sum series implementation

• In the EXPLORER window, right-click on openmp and select New File.

• Type sum_series_for_2.c as the file name and hits Enter.
