[mpich-discuss] Running mpiexec on WIndows Computers

Fri Feb 20 18:15:27 CST 2009

If I used -hosts 2 option then the mpiexec will hang until I enter ctrl-C.
(the hello.exe is running in remote computer already.)

After ctrl-C, I got:

mpiexec aborting job.

[0] Hello world

[1] Hello world

Job aborted:

Rank: node: exit code[: error message]

0: ipaddress_1:  123: mpiexec aborting job

1: ipaddress_2: 123 

BTW, -hosts 1 works for both computers.

Hi,

 Please run the command below and provide us with the output
(system_info_machines1_2.log),

      mpiexec -hosts 2 IPADDRESS_OF_MACHINE1 IPADDRESS_OF_MACHINE2
systeminfo  > system_info_machines1_2.log

 Instead of trying out cpi.exe try compiling and running the following
helloworld program,

################# hello world #####################

#include <stdio.h>

#include "mpi.h"

int main(int argc, char *argv[])

{

     int rank = -1;

     MPI_Init(&argc, &argv);

     MPI_Comm_rank(MPI_COMM_WORLD, &rank);

     printf("[%d] Hello world\n", rank);

     MPI_Finalize();

}

################# hello world #####################

 Compile the program above, copy it to c:\temp, and run it as follows,

      mpiexec -hosts 2 IPADDRESS_OF_MACHINE1 IPADDRESS_OF_MACHINE2
c:\temp\hello_world.exe

 Let us know the results.

Regards,

Jayesh

I copied cpi to c:\temp, but still the same problem.

 A quick note -- Copy cpi.exe to a non-user specific directory like c:\temp
(Move cpi.exe from "c:\Users\zhong.wu\Documents" to "c:\temp") on both the
machines and try running your MPI job.

I have tried hostname and ipaddress both.

I attached the spmd and mpiexec logs from one of my computer.

Thanks.

Please provide as much information in your email as possible. Did you try
using machine file with ipaddresses (instead of hostnames)?

The machine file didn't work.

>> But from one remote I have to use ipaddress to start remote
process...

 So did you try running cpi by specifying ipaddresses ? Also let us know
whether the "-machinefile" option works for you (make sure that you
specify ipaddresses of the machines in your machine file).

Regards,

Jayesh

I can run cpi on both remote computers with -hosts 1, but not two
computers at same time. But from one remote I have to use ipaddress to
start remote process.

I turned off firewall completely, still the same problem.

I found the cpi.exe processes are already started in both computers
(remote and local).

1) Did you try executing cpi.exe remotely from both the machines
(mpiexec -hosts 1 remotecomputer... from both the machines)?

2) Do you have any windows firewall or third party firewall running on
your machine (turn it off if its running)?

3) Try specifying the ipaddresses of machines (Due to DNS config issues
one host may not be able to resolve the other hosts name) instead of
hostnames.

Jayesh

Yes. I am using the latest mpich2 version 1.08. one of my computer is
running vista and the other one is windows server 2008. I will try
machinefile.

Hi,

 Did you recently upgrade to the latest version of MPICH2 (1.0.8)?

(PS: I just verified that I can run cpi across two Win XP machines using
a machinefile or the "-hosts" option.)

Regards,

Jayesh

I am setting up mpich2 on two windows computers. I created same

remote computer through

mpiexec -hosts 1 localcomputer 2 c:\samples\cpi.exe

mpiexec -hosts 1 remotecomputer 2 c:\samples\cpi.exe

but I cannot run the sample on both computer at once

mpiexec -hosts 2 localcomputer 2 remotecomputer 2 c:\samples\cpi.exe

mpiexec will hang after the interval.
