[Pw_forum] About parallel problem on SGI Altix 3700

[Chao]

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
