It is solved, half by you all guys and half by myself. I really needed to add "./" but also I had some things to fix in nfs. I was sharing just the mpich folder, not the whole environment of my tools, so it couldn't catch the cpi file in the other computers. But thanks a lot!<br>

><br>><br>><br>> Hello Rajeev and Pavan,<br>><br>> Thanks a
lot for your help on building MPICH correctly. I have removed<br>> mpd
(apt-get purge mpd) and then reinstalled MPICH. I was so happy<br>> when I
saw it was working T_T. A the looping test, with 1,000,000<br>> loops too
431 seconds to be performed. Do you think it is a good rate?<br>><br>>
But now what brings me to here is what comes next. I have followed all<br>>
instructions from the "quick start" until this line:<br>><br>> mpiexec
-n 5 examples/cpi<br>><br>> and it didn't work, returning this
error:<br>><br>> problem with execution of examples/cpi on falcon:
[Errno 2] No such<br>> file or directory<br>> problem with execution of
examples/cpi on falcon: [Errno 2] No such<br>> file or
directory<br>><br>> and stopped in the second line.<br>><br>> Then
I tried to submit this command inside of the "examples" folder,<br>> and it
returned:<br>><br>> problem with execution of cpi on eagle: [Errno 2] No
such file or<br>> directory<br>> problem with execution of cpi on
falcon: [Errno 2] No such file or<br>> directory<br>> problem with
execution of cpi on falcon: [Errno 2] No such file or<br>>
directory<br>> problem with execution of cpi on eagle: [Errno 2] No such
file or<br>> directory<br>> problem with execution of cpi on eagle:
[Errno 2] No such file or<br>> directory<br>><br>> Now I can see that
it failed for the five processes. I have set and<br>> mounted the nfs on
the node (until now I'm setting up just one<br>> computer, later I'll close
this one) and it is working ok. So my<br>> server is named as eagle and the
node, falcon. mpd is running in both<br>> computers, this I can see
utilizing the mpdtrace command. when I<br>> submit the example "mpiexec -l
-n 10 hostname" it returns me this:<br>><br>>
root@eagle:/modeling/mpich2-1.0.7/examples# mpiexec -l -n 10 hostname<br>>
1: falcon<br>> 2: eagle<br>> 3: falcon<br>> 5: falcon<br>> 4:
eagle<br>> 7: falcon<br>> 8: eagle<br>> 6: eagle<br>> 0:
eagle<br>> 9: falcon<br>><br>> And then I think it is ok.<br>> the
paths are set and ok, so I don't understand why is that returning<br>> that
error, not found, if even if I execute it inside of "examples"<br>> folder
it doesn't work (of course I take off the examples part, or<br>> even add
the whole path).<br>><br>> Ad I have a doubt, a stupid one, sorry, every
time I restart the<br>> computer I have to point the path for the bin
directory, and then it<br>> works. Is there any way to set it
automatically?<br>><br>> Sorry for trouble you two so much. And thank
you two until now for<br>> your attention!<br>><br>>
