- * SUBROUTINE KERNEL( TK) replaces the Fortran routine in LFK Test program.
- ************************************************************************
- * *
- * KERNEL executes 24 samples of "C" computation *
- * *
- * TK(1) - total cpu time to execute only the 24 kernels.*
- * TK(2) - total Flops executed by the 24 Kernels *
- * *
- ************************************************************************
- * *
- * L. L. N. L. " C " K E R N E L S: M F L O P S *
- * *
- * These kernels measure " C " numerical computation *
- * rates for a spectrum of cpu-limited computational *
- * structures or benchmarks. Mathematical through-put *
- * is measured in units of millions of floating-point *
- * operations executed per second, called Megaflops/sec. *
- * *
- * Fonzi's Law: There is not now and there never will be a language *
- * in which it is the least bit difficult to write *
- * bad programs. *
- * F.H.MCMAHON 1972 *
