Dear Kohlmeyer thanks for your reply. i compile espresso 5.0.2 again and remove all library of openmpi & mpich2 . then run mpirun -np 8 and give this massage : The program 'mpirun' can be found in the following packages: * lam-runtime * mpich-bin * mpich-mpd-bin * mpich-shmem-bin * mpich2 * openmpi-bin Try: apt-get install <selected package> i install only mpich2 but give again this error :
from test_input_xml: Empty input file .. stopping from test_input_xml: Empty input file .. stopping from test_input_xml: Empty input file .. stopping from test_input_xml: Empty input file .. stopping i remove mpich2 and install openmpi-bin but give again above error. what i can do?
