[Pw_forum] mpich-mpi is neccesary !? or lam-mpi is sufficient !!

Dear Quantum Espresso Users

 

Due to my problem in running example 01:

 

I have installed parallel Quantum Espresso successfully and tried to 
 run the exapmle 01.
 at first I tried to run the example 01 from the root but the program 
 did't run and then I went out of the root for running (this is the 
proposed by the QE). the first problem solved by going out of the 
root. Once I could run the example 01 but amazingly I cannot now !!. 
when I run the exaplme 01 the program stopped at this line:
 
 running the scf calculation for Si... and did not continue
 
 and any CPU's did not work and there is not any results.
 My system is AMD (3 cores) and LAM-MPI works well. but I think that 
the problem is related to lam ! since at first time that I tried QE 
aked me to boot the lam by lamboot and I do to continue. and it is so 
interesting that I runned once and cleaned the temporary but again I 
can not !!!
 
 
Ngoc Linh Nguyen  has suggested to use mpich-mpi instead of lam-mpi. 
 
Is there any other solution to this problem ?  really one can not use lam-mpi with QE ? 
 
Many thanks
