[mpich-discuss] symbol lookup error

[Haider Abbas]

Dear all,

In continuation with my previous email, I got success in running quantum
espresso on my cluster.
But now I am facing another problem.
with the command
mpiexec -f hosts -n 10 ./pw.x -i relax2.in > out.out &

QS run perfectly, but as I increase the number of core like this

mpiexec -f hosts -n 30 ./pw.x -i relax2.in > out.out &

it gives an error


mpiuser at master:~/qe-29-11/bin$ mpiexec -f hosts -n 30 ./pw.x -i relax2.in >
out.out &
[4] 2131
mpiuser at master:~/qe-29-11/bin$ ./pw.x: symbol lookup error: ./pw.x:
undefined symbol: mpi_initialized_
./pw.x: symbol lookup error: ./pw.x: undefined symbol: mpi_initialized_

./pw.x: symbol lookup error: ./pw.x: undefined symbol: mpi_initialized_
./pw.x: symbol lookup error: ./pw.x: undefined symbol: mpi_initialized_

However I have recent hydra supported version of mpich on all the nodes
I request you all to kindly help me to overcome this Problem.
