While in gfortran, the implementation of MATMUL is faster than default BLAS, ifort clearly shows that mkl-blas is faster. figure 1: Matrix-vector multiplication. Web14 jun. 2024 · The speed differences of factor 10 for integer write remain even without a do loop. Further, no do-look will cause gfortran to write a single line of output, ifort to write 3Mio lines.
