Dear All
I met a problem when using PWscf for parallel computation. I submitted my job
in the following format:
mpirun -np 8 pw.x -npool 4 < .in > .out
But my job only ran on one CPU, and some messages were listed:
MPI: could not run executable (case #3)
MPI: No details available, no log files found
When I complied PWscf, some errors appeared when make all:
IPO Error: unresolved : mpi_conversion_fn_null_
Referenced in ../Modules/parallel_include.o
Referenced in ../Modules/ptoolkit.o
Referenced in libiotk.a(iotk_error.o)
Can anyone help me?
Best regards
