<P><FONT SIZE=2> Hi,<BR>
You might also have to open up the port used by SMPD to listen for incoming connections (port 8676 by default --- Or use the "-port" option while starting smpd to specify the port to listen. If you use the "-port" option with smpd make sure that you specify the same port number when running your job using mpiexec.)<BR>
Let us know if it works for you.<BR>
<BR>
(PS: If that does not work please run smpd and mpiexec in verbose/debug mode and send us the output. smpd -d / mpiexec -verbose. Also send us the complete error message that you get when running your MPI application.)<BR>
<BR>
Regards,<BR>

Hi,<BR>
<BR>
I installed MPICH2 on 2 64-bit Linux machines under my home directory.<BR>
The firewall of both machines is turned on.<BR>
When I ran a program across these 2 machines, I got an error message such as<BR>
"abort: unable to connect to xxx".<BR>
So I checked with the system administrator and he enabled 11 TCP ports for me to use.<BR>
The port range is from 12505 to 12515.<BR>
Also, I set the MPICH_PORT_RANGE environment variable with the above range.<BR>
However, I still got the same error message as mentioned before.<BR>
So, how to fix this problem?<BR>
<BR>
Thank you very much,<BR>
<BR>
