Hi,<br><br>
I'm trying to set-up mpich2 (last version) on a linux cluster (ubuntu
gutsy) and I'm having some problems using root mpd from a normal user.
I'm following the tests indicated in the manual, and everything is fine
using mpd as a normal user.<br><br>
Running mpd at boot from root, when I'm on the server machine, a normal
user is able to run mpiexec -n 1 hostname getting the correct hostname
answer.<br><br>
On the slave machine, on the contrary, it results with the following
message:<br><br>
/opt/mpich2/1.0.6p1/intel10.1/bin/mpdroot: open failed for root's mpd
conf filempiexec_cluster3 (__init__ 1190): forked process failed;
status=255<br><br>
It seems to be a problem relevant to the /etc/mpd.conf file. But this
file is the same I have on the server (with same permissions).<br><br>
The command is executed regularly on the slave machine with sudo mpiexec
-n 1 hostname.<br><br>
Could it be a problem relevant to the fact that, the mpich2 directory is
mounted from the server via nfs?<br><br>
Regards.<br><br>
