The execution loops are all small so that they will fit in + any cache. Flops.c can be used along with Linpack and the Livermore + kernels (which exercise memory much more extensively) to gain further + insight into the limits of system performance. The flops.c execution + modules include various percent weightings of FDIV's (from 0% to 25% + FDIV's) so that the range of performance can be obtained when using + FDIV's. FDIV's, being computationally more intensive than FADD's or + FMUL's, can impact performance considerably on some systems. |
