Abstract	Several speeding-up techniques incorporated in the spherical harmonic transform library (ISPACK), which has been developed by the speaker, are explained. Outline of optimization for the latest CPUs (Intel's CPUs with avx512 instructions and Fujitsu's A64FX) and results of benchmark computations are also explained.
