Function ext_base_op_par 

pub fn ext_base_op_par<PE, F, Func>(
    lhs: &mut [PE],
    rhs: &[PE::PackedSubfield],
    op: Func,
)
where
    PE: PackedExtension<F>,
    F: Field,
    Func: Fn(usize, PE, PE::PackedSubfield) -> PE + Sync,

A multithreaded version of the function directly above, use for long arrays on the prover side

Preconditions

• lhs.len() must equal rhs.len() * PE::Scalar::DEGREE.
