[MPICH] Mpich2 mpd ping one side working only

[Luiz Mendes]

Hi all,

I have been analysing a problem about comunication between mpd processes on
several PCS.

I want to know, if mpdboot, at launch time, requests comunications between
processes in a ciclic manner.

Other doubt is, i have the following pcs:

fisio1
fisio2
fisio3

I have Mpich2 installed in a shared folder located at fisio1.

Well, other pcs have this folder mounted on it folder structures. If i
configure MPDBOOT -n 2 -f hostfile, it works for the following pairs

fisio1 and fisio 2
fisio1 and fisio 3

And when i execute mpdboot from fisio2 for example, it returns for me the
following message:

mpdboot_fisio2 (handle_mpd_output 374): failed to ping mpd on fisio1; recvd
output={}

I have access from fisio2 to fisio1, when i give the following command: ssh
fisio1 date, from fisio2 it works ok.

So why it is happening, do you know something that could cause this?

The strange thing is that Mpich1 it works perfectly with all nodes.

Thanks
Luiz Mendes
