◆ executeFast()

static KahanSum sc::op::executeFast ( size_t &  i,
size_t  nSize,
const double *  pCurrent 
)
inlinestatic

This function task is to choose the fastest method available to perform the sum.

Parameters
i
nSize
pCurrent

Performs the sum of an array.

Note that align 16 will speed up the process.

inline

Performs one step of the Neumanier sum between doubles Overwrites the summand and error @parma sum.

Parameters
err
value
