# OpenMP Parallel Efficiency

The OpenMP Parallel Efficiency (OpenMP PE) describes the parallel execution of the code in OpenMP.

Similarly to the original POP metrics model, can be computed by multiplying the OpenMP Load Balance Effiency (OpenMP LBE) and OpenMP Communication Efficiency (OpenMP CE) metrics as follows:

$OpenMP\_PE = OpenMP\_LBE \times OpenMP\_CE$
