Dear all,
I am compiling gromacs 4.0.7 on AIX 5.3 with "./configure --enable-mpi --enable-ppc-sqrt=1 --enable-ppc-altivec --disable-fortran --with-fft=fftw3". The source codes under src/gmxlib/nonbonded/nb_kernel_ppc_altivec/ are compiled and archived. However, when generating the executable binary "mdrun", it seems that the object file generated by "mknb" is used to link for mdrun. Therefore, I cannot make full use of SIMD instruction to accelerate the computation on power architecture. Does anyone know what should I do to let mdrun call nb_kernel**_ppc_altivec instead of nb_kernel***? Thanks a lot.
