[mpich-discuss] mpich user problem: Unable to load 'mpich2.dll', error 1114

[Kuraisa, Roy J (BOSTON)]

Hi,
Summary:
--------
On Windows, I get the above error with the additional error message:
     "Attempting to use an MPI routine before initializing MPIC"
I get both error lines numerous times when I execute a test app as
follows (stripped down):
    c:\> mpiexec  -hosts 2 server1 128 server2 32 \\ns\test.exe 

The app runs fine (or so I think) when I reduce the number of processes:
    c:\> mpiexec  -hosts 2 server1 64 server2 32 \\ns\test.exe 

This is really just a stress test because server1 only has 16
cores/processors; and server 2 only has 2 cores/processors.  But I don't
think I should get this error.  I noticed that another person reported a
similar problem in dec 2009 but I did not see how this was resolved.  

Any suggestions or ideas?  tia.

Background:
-----------
I've installed MPICH2 1.2.1 binary release on two 64-bit Wiindows
servers.  The spec's on these servers are:

Server1
-------
a. Windows Server 2003, 64-bit, SP2
b. 16 cores/processors
c. 8GB memory
d. Physical computer

Server2
-------
a. Windows Server 2003, 64-bit, SP2
b. 2 cores/processors
c. 8GB memory
d. Virtual Machine


cheers, roy
