<div dir="ltr"><div>I have installed mpich2 1.0.7 on 2 XP Pro hosts and am trying to run the cpi process on both hosts with the command</div>
<div> </div>
<div>mpiexec -hosts 2 images17 images17 cpi</div>
<div> </div>
<div>where images16 and images17 are the hosts and cpi is the supplied example application and get the error:</div>
<div> </div>
<div>abort: unable to connect to images16</div>
<div> </div>
<div> </div>
<div>I have checked passwords and regsitration is the same on both hosts. Firewalls are both down. Host names defined in hosts file under system32. I have ensured that smpd is operating on both machines. Usernames and password are the same on both hosts and have both been delegated. I have gone through the mpich2 user manual and find no way forward with this. Is there anything else I could try ?</div>
<div> </div>
<div>Would it help if I listed the output from the mpiexec with the verbose switch on.</div>
<div> </div>
<div>Regards, bob</div></div>
