Line 69:

In the light of these guidelines, it was deemed the only viable approach to use a collection of "paper-and-pencil" benchmarks that specified a set of problems only algorithmically and left most implementation details to the implementer's discretion under certain necessary limits.

NPB 1 defined eight benchmarks, each in two problem sizes dubbed ''Class A'' and ''Class B''. Sample codes written in [[Fortran#FORTRAN_77FORTRAN 77|Fortran 77]] were supplied. They used a small problem size ''Class S'' and were not intended for benchmarking purposes.<ref name="rnr94007"/>
