Hi, 
You need to have the same username (with the same password) on both the machines for launching MPI jobs (Or use a domain user on both machines). Create local users on both the machines with the same username/password and let us know if MPICH2 works for you.

Jayesh

sorry, i forgot to mail to mpich-discuss, my bad... 

Can you ping one machine from the other (192.168.1.3 from 192.168.1.5 and 192.168.1.5 from 192.168.1.3) ? 
=> yes i can, both machine can ping each other 


Do you have the same username on both the machines (And from your email I am assuming that you are able to run your job locally on each machine, right ? )? 
=> no, the username are different, but the password and passphrase is same 
yes, i am able to run my job locally on each machine, 
the error message said that "unable connect to xxxx" 
i've tried on both machine, but the error message just the same.. 

can anybody help me with this problem? 

thx

dear jayesh, 




i'm sorry for mailing you, but from what i found in internet, you are the guy that often help people with MPICH2, 

e.g in this link 

http://lists.mcs.anl.gov/pipermail/mpich-discuss/2009-February/004657.html 

you help the guy, 

i have the same problem, when i try to running MPICH2 with 2 computers connected by LAN cable, it is said 
"abort : unable to connect to 192.168.1.3" 

note : i made the ip static, my computer is 192.168.1.5 and the other one is 192.168.1.3 
i test running the cpi.exe and some other parallel files in my single computer that has procesor core 2 duo, and it run correctly 
i use mpich2 1.3 
both machine is using windows 7 profesional 

seem like i have done what you have suggest in that link, 
i turn off the firewall 
i made sure both machine run the same smpd version 
i made sure both machine installed MPICH2 correctly, (run in admin priviledge, for everyone and default passphrase) 
i use "mpiexec -register -user 1" and then i didn't enter the username, i just simply press "enter" button and then i enter the password "behappy" 
i validated that user then i run mpiexec -hosts2 xxxxxxx xxxxxx - user 1, which didn't work 
i made both machine has same logon password, "behappy" 

thank you, 

this is the verbose
