Table II.

Comparison of gpu computation times for arrays consisting of 512 and 202 elements and 2563 field points computed using rsm, fnm, the 1-d convolution algorithm, and the 2-d convolution algorithm.

Array Size RSM FNM 1-D Convolution 2-D Convolution
512 172 394 s 261 s 0.744 s (0.55 s) N/A
202 134 683 s 204 s N/A 0.712 s (0.59 s)

All computation times are in seconds. The RSM and FNM timing is for the 0.01% accuracy case studied in Table I.

Time in parentheses is the time required to pre-compute the single-piston field using the FNM and 0.01% accuracy.
