If the ML evolutionary tree is to be validated for high bootstrap values, the computational power requirement is high. Not parallel do basic impossible.
So under a raxml, under Linux there are several ways to compile, look at the hands of the machine to support the AVX instruction set, so choose Avx-mpi way.
Install Openmpi First, according to the online tutorial compiled on line, is slightly slow.
But after the installation of MPICC, and then to compile raxml found that the GCC version is not high enough to support AVX, although do not know how much speed AVX can bring, but for learning to consider or try to upgrade GCC bar
Under a gcc4.8.1, be careful to download the dependent library before you make the translation./contrib/download_prerequisites, then compile and install
