omp parallel for simd

Specifies a parallel region that contains a loop to execute with Single Instruction Multiple Data (SIMD) instructions.

Syntax

#pragma omp parallel for simd [clause[, clause, ...]]

for-loop

clause

Can be any of the following:

for loop

Must be in the following form:

for (init-expr; test-expr; incr-expr)

structured-block

This pragma is a shortcut for a parallel region that contains a single SIMD loop construct.

Example: Compiling with SIMD instructions in a parallel loop with a simple for loop
#pragma omp parallel for simd schedule(static,10) { for (i=0; i<N; i++) { a[i] = b[i] * c[i]; } }
