Hi Haider<br>
<br>
Mpiexec doesn’t like the -f option. Just for fun, did you try it without the hosts file, please?<br>

<div>Dear all,<br>
<br>
</div>
I have prepared a 10 node ubuntu based cluster, following the guidelines described in "<a target="_blank" href="https://www-users.cs.york.ac.uk/%7Emjf/pi_cluster/src/Building_a_simple_Beowulf_cluster.html">https://www-users.cs.york.ac.uk/~mjf/pi_cluster/src/Building_a_simple_Beowulf_cluster.html</a>"<br>
<br>
</div>
<div>I have followed each and everthing as mentioned in the above documents.<br>
</div>
everything is Ok, now I try try to check the cluster by executing the command <br>
<br>
mpiuser@master:~$ mpiexec -f hosts -n 3 /home/mpiuser/bin/cpi<br>
</div>
<br>
then this return with the error.<br>
<br>
<br>
mpiexec was unable to launch the specified application as it could not find an executable:<br>
<br>
Executable: -f<br>
Node: master<br>
<br>
</div>
I could not solve this. I don't know why this happening. However, executable "cpi" is in /home/mpiuser/bin.<br>
<br>
</div>
I request you all to kindly help me to overcome this problem.<br>
</div>
thanking in advance.<br>
