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

[Jayesh Krishna]

Hi,
 This error occurs because we link the VS libraries statically (it makes our life a lot easier). This is a limitation in the VS C libraries if you link your code statically.
 We do not plan to change static linking of the VS runtime libs unless there is a legitimate test case showing the problem.

Regards,
Jayesh

mpich user problem: Unable to load 'mpich2.dll', error 1114 

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
