That is, - vector processor performance will reflect scalar performance - which will lie far below expected vector performance. Also, - the percentage of FDIV's is somewhat 'high' at 9.6%. - MFLOPS(2) Weightings: FADD 38.2%, FSUB 9.2%, FMUL 43.4%, FDIV 9.2%. - The code for MFLOPS(2) is fully vectorizable. The percentage - of FDIV's however is somewhat on the 'high' side. - MFLOPS(3) Weightings: FADD 42.9%, FSUB 3.4%, FMUL 50.7%, FDIV 3.4%. - The code for MFLOPS(3) is fully vectorizable. The percentage - of FDIV's is however 'moderate' at 3.4%. - MFLOPS(4) Weightings: FADD 42.9%, FSUB 2.2%, FMUL 54.9%, FDIV 0.0%. - The code for MFLOPS(4) is fully vectorizable. The percentage - of FDIV's is however zero. - ---------------------------------------------------------------------------
