[MPICH] Connection attempts fail with hosts using MPICH 1.2.5

[Jason Michaels Mcgill]

Hello:

I realize that most now use MPICH2, but the 'List description' said that 
MPICH 1.2x problems can still be discussed here.

I am using MPICH 1.2.5 for multi-block runs. I explicitly give the ip 
addresses of the hosts that I use -and the number of threads they will 
provide- in a configuration file (configfile.mpi).

The batch file created provides a '-logon' mpirun prompt, which requests 
an account and user password. I make sure that MPIConfig.exe (located in 
the bin directory of my MPICH folder) provides the hosts that I wish to 
use, and I select them to make them available for a multi-process run.

I enter the account number and password in the batch file, which, if mpich 
was working properly, would then inform me that my program is running, and 
which processes the simulation is alive on. However, I get the following 
message:

"easy_connect::WSAETIMEDOUT error, re-attempting easy_connect(the ip 
address)"

Once the re-attempt has failed, this message appears:

"Error: ConnectToMPD(ip address:8675): easy_connect failed: error 10060, A 
connectio attempt failed because the connected party did not properly 
respond after a period of time, or established connection failed because 
connected host has failed to respond.

MPIRunLaunchProcess: Connect to (ip address) failed, error 10060"

This error occurs for each remote process I wish to use as a host. I have 
consulted the MPICH user guide, and I have seen nothing detailing an error 
10060.

The last thing I should say is that the runs I attempted to perform were 
using Windows XP and Windows 2000 OS machines.

This probably seems very vague, but this is truly as detailed as I can 
make it, because the error seems to be ambiguous. But I appreciate any 
help that anyone can provide.

Thank you,
