Hello,<br><br>The problem is that if your working without root privileges, like i am in the school fedora images loaded from pxe to the lab's computer, maybe this could be helpful. Additionally the fedora image is set up so that no ssh without password can be made (don't ask me why or how). <br>
I have to check hydra out, once that on my home computer i'm still using mpdboot.<br><br>The best regards,<br>SwatchPuppy<br><br><div class="gmail_quote">On Sat, Jun 5, 2010 at 3:36 PM, Pavan Balaji <span dir="ltr"><<a href="mailto:balaji@mcs.anl.gov">balaji@mcs.anl.gov</a>></span> wrote:<br>

You need to setup passwordless ssh on your system, as described in the README. You can google for "passwordless ssh" to figure out how to do that.<br>
<br>
Btw, there's not going to be a next version of MPD -- in the MPICH2 1.3.x series, we have moved to a new process manager called Hydra. But that still requires a passwordless ssh.<br>

Hello all,<br>
<br>
I've been trying to setup a cluster in my university labs, but i can't do ssh to the others computers without password. This is a problem if mpdboot is used to start up the mpd ring, because it will asks for a lot of passwords at the same time.<br>
So I've edited the mpdboot python file and added *mpd.wait()* in line 361 for mpich2 1.0.6, and 375 for mpich2 1.2.1p1, just after *mpd = Popen4(cmd,0)*, in this way it will ask a password per connection sequentially.<br>
<br>
<br>
Hope that this can help someone, or affect change in the next version of mpdboot.<br>
<br>
The best regards,<br>
SwatchPuppy<br>
