[mpich-discuss] Unable to connect issue

[Jayesh Krishna]

Hi,

# Can you run the MPI program on a single host ? (i.e., mpiexec -n 2
cpi.exe)
# Can you try specifying ipaddresses of the hosts instead of the hostnames
? (i.e., mpiexec -hosts 2 IPADDRESS_OF_IMAGES16 IPADDRESS_OF_IMAGES17
cpi.exe)

    If the above suggestions don't work please provide us the verbose
output of smpd and mpiexec. To get the verbose output of smpd & mpiexec,

# Stop any instances of smpd using, smpd -stop, command
# Run smpd in debug mode using, smpd -d, command
# Run mpiexec in the verbose mode using the "-verbose" option of mpiexec.

   Let us know the results.

(Note: In the command that you listed in your email both hostnames are the
same -- there is no images16 specified with "-hosts" arg of mpiexec. I am
assuming you meant "mpiexec -hosts 2 images16 images17 cpi.exe")

Regards,
Jayesh

Hi,

I am running XP Pro on the machines and am therefore using smpd. As far as
I know the mpd is used in the unix/linux environment. The smpd is
operational on both PCs. The local check for the status os the smpd on
either machine shows that they are running.  When i do a remote check with
smdp I get the same message.i.e.

smpd -status <remotehostname>
abort: unable to connect to <remotehostname>



Regards, bob

do you have mpd ring running and connected on both machines?

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
mpiexec -hosts 2 images17 images17 cpi
where images16 and images17 are the hosts and cpi is the supplied example
application and get the error:
abort: unable to connect to images16
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 ?
Would it help if I listed the output from the mpiexec with the verbose
switch on.
Regards, bob
