$ParallelizeFeynCalc is a global switch that enables
FeynCalc to evaluate some subroutines on using parallel kernels. It
should be explicitly activated by setting
$ParallelizeFeynCalc to True. However, before
that one should evaluate LaunchKernels[n] with
n being the number of parallel kernels to launch. The
default value is False.
$ParallelizeFeynCalc\text{False}
