The virtual machine setup is not something that we typically test at our test environment. I have created a ticket (<a href="https://trac.mcs.anl.gov/projects/mpich2/ticket/1445" target="_blank">https://trac.mcs.anl.gov/projects/mpich2/ticket/1445</a>) for the same.

Hi Jayesh,<br>
<br>
Firewalls are disabled on the machines. The machines are actually running on VMware ESX3.5 in a intel xeon server. They are physically housed together but logically separated by vmware. No problems with pinging the servers.<br>
<br>

Hi,<br>
This could be a firewall issue. Did you turn off Windows firewall on both the machines ?<br>
<br>

Hi,<br>
<br>
Thanks for the response, a similar problem occurred for cpi.exe, this time round it lies in MPI_Bcast, with same network errors. What puzzles me is the fact that I could run the program remotely on the other nodes through the<br>
>mpiexec -host remote_node -n 4 cpi.exe<br>
<br>
On a program that uses purely Send and Recv commands, I didn't have problems running on multiple nodes using the machinefile.<br>
<br>
In the case of network error, are there any settings that I have to take note for windows? Such as DCOM settings, remote access etc. The users for the nodes are all administrators, so I presume there won't be any problems with remote file access and launch of programs.<br>
<br>
Regards,<br>
Zuwei<br>

Hi,<br>
>From the error message it looks like a network connectivity issue (not related to MPI_Barrier()). Can you send us a test program that fails ?<br>
Can you run cpi.exe (c:\program files\MPICH2\examples\cpi.exe) across the nodes ?<br>
<br>
Regards,<br>

Problems with Barriers on MPICH2-1.3.2p1 on Windows XP and Windows Server 2008<br>
<br>
Hi users,<br>
<br>
I have some issues with MPI_Barrier() on the MPICH2-1.3.2p1 build on Windows.<br>
On a single node, the operation works flawlessly, however when the program is scheduled to run on multiple nodes I get the following errors.<br>
<br>
mf.txt<br>
node0:1<br>
node1:1<br>
<br>
>mpiexec -machinefile mf.txt -n 2 mpi_test.exe<br>
<br>
Fatal error in PMPI_Barrier: Other MPI error, error stack:<br>

<br>

rank: node: exit code[: error message]<br>

1: node1: 1: process 1 exited without calling finalize<br>
<br>
Additional Notes:<br>
When running against code without any MPI_Barrier calls, no problems with were encountered (ie: on multiple nodes send and recv). Based on that I presume my settings were correct and the problem might lie in the barrier implementation on windows.<br>
<br>
Any help to identify the problem here would be great.<br>
<br>
<br>
Regards,<br>
Zuwei<br>
