Float cps::print_flops (  char *  cname, char *  fname, unsigned long long  nflops, struct timeval *  start, struct timeval *  end )

Prints the FLOPS rate to stdout. The user counts the operations and calls gettimeofday before they start and after they finish to get the elapsed time. The class name and method name are printed with the FLOPS rate. Parameters: cname  The class name. fname  The method name. n_flops  The number of floating point operations performed start  The initial result of calling gettimeofday end  The final result of calling gettimeofday Returns: The FLOPS rate.

Float cps::print_flops (  unsigned long long  nflops, struct timeval *  start, struct timeval *  end )

Prints the FLOPS rate to stdout. The user counts the operations and calls gettimeofday before they start and after they finish to get the elapsed time. Parameters: n_flops  The number of floating point operations performed start  The initial result of calling gettimeofday end  The final result of calling gettimeofday Returns: The FLOPS rate.

Float cps::print_flops (  char *  cname, char *  fname, unsigned long long  nflops, Float  time )

Prints the FLOPS rate to stdout. The user counts the operations and calls dclock before they start and after they finish to get the elapsed time. The class name and method name are printed with the FLOPS rate. Parameters: cname  The class name. fname  The method name. n_flops  The number of floating point operations performed. time  The elapsed time in seconds. Returns: The FLOPS rate.
