[Pw_forum] parallel environment not found

Dears Paolo, Alex, Gerardo,

Many thanks to all your advices.
I used the system ifc7.1.044+icc7.1.042+mkl61.
To install mpich2, I followed the steps:
CC=icc
CXX=icc
FC=ifc
export CC CXX FC
./configure --enable-f90
make
make install

then, for espresso, I used:
./configure --enable-shared
added -static-libcxa in make.sys
make all

it compiled successfully.
The example01 run successfully on a single processor but fails when I assign
values for PARA_PREFIX and PARA_POSTFIX.
But I used the instruction on page 37 of UG:
mpiexec -n 10 ../../../bin/pw.x -npool 5 -in si.scf.david.in >
si.scf.david.out
It worked!!
It does not become clear for me why my previous experience continuously
failed.
Once again I thank you.

Best regards
Mahmoud
