Both  
ssh localhost echo $WIENROOT
ssh titin-desktop is the hostname) echo $WIENROOT

issue:
/home/titin/Programas/WIEN2k

which is the proper WIENROOT.

In both cases YES

titin at titin-desktop:~/Programas/WIEN2k/titin/benchmark/test_case$ x lapw1
 LAPW1 END
127.187u 0.584s 2:08.12 99.7%	0+0k 10912+33256io 55pf+0w

Do you mean just issuing all those commands exactly as you wrote? I log in:

titin at titin-desktop:~$ ssh titin-desktop;cd ~/Programas/WIEN2k/titin/benchmark/test_case;lapw1 lapw1.def
Linux titin-desktop 2.6.27-10-generic #1 SMP Fri Nov 21 19:19:18 UTC 2008 x86_64

I left it there for about 3 hours and then logout, but ssh hangs. After Control+C I get:

forrtl: error (69): process interrupted (SIGINT)
Image              PC                Routine            Line        Source             
lapw1              00000000004A5EB2  Unknown               Unknown  Unknown

Stack trace terminated abnormally.

Thus it seems something was running, after all, but was stuck somehow, since it was taking forever to run this simple lapw1 process for the test_case.

Thanks a lot for your input!
