[Pw_forum] Does QE support the old MPICH and gfortran?

[GAO Zhe]

Dear QE developer and users:
I borrowed a cluster from other department. During configure the QE package, both of v4.3.2 and v4.1.3, it showed "Parallel environment not detected".
Then I checked ./install/config.log ( in QE v4.3.2 ), and found the error message like:
configure:2884: mpif90 -V >&5
f95: '-V' must come at the start of the command line
configure:2887: $? = 1
configure:2895: checking whether we are using the GNU Fortran compiler
configure:2914: mpif90 -c -g -O2  conftest.F >&5
configure:2920: $? = 0
configure:2937: result: yes
configure:2943: checking whether mpif90 accepts -g
configure:2960: mpif90 -c -g  conftest.f90 >&5
configure:2966: $? = 0
configure:2982: result: yes
configure:3353: WARNING: parallel compiler mpif90 uses gfortran, but serial compiler mpif90 was detected
configure:3355: WARNING: assuming F90=gfortran, discarding mpif90
The cluster is running on Fedora release 8.
mpi version is mpif90 for 1.2.7 (release) of : 2005/11/04 11:54:51, which was compiled by gfortran ( gcc version 4.1.2 20070925 (Red Hat 4.1.2-33) ).
Each node is based on Intel dual-core CPU.
The parallel environment can be detected by Abinit ( unfortunately, Abinit cannot pass the mpi compiling as well, even I tried Abinit v5.3.5, which was released in 2007 ).
Do I have to use an older version ( ealier than 4.1.3 ) QE? Or, are there some other methods to overcome this problem? Since this cluster does not belong to our lab, we cannot update the mpi version and install ifort.
