Dear L. Marks,

I did your suggestions but unfortunately I have no success yet.

I tried it with 8 and 4 options. My computer is an xeon quadcore, but I am
not sure if it is dual.  Here is the output of /proc/cpuinfo

This fail because it only finish lapw0.  It genarate lapw1_1,2,3.error but
they are empty.

Yes, I can do ssh without password.

I did. I dont got any error. but an strange message:
----------------------------------------------------it is a long message. I
have the message in a file---------------------------
sleep 1
Pseudo-terminal will not be allocated because stdin is not a terminal.
ssh: cd /home/nilton/pesquisa/dftCalc/calWien/gaxtl1-xas/075/case;time
mpirun -np 4 -machinefile .machine: Name or service not known
end
------------------------------------------------------------------------------------------------------------------------------

It seems that are looking for .machine file. but It dont exist. I can paste
this command because it dont have the exec. file
