[mpich-discuss] Problems with conversion from 32-bit to 64-bit

[Euan Barlow]

Hi Jayesh,

Thanks for your quick response.

I have now reinstalled the 64-bit visual studio SP1 runtime and recompiled the code but it still produces the same error. I've noticed that if I select more than 3 processors, the following error code is produced in addition to the previous one:

"Error posting readv, An established connection was aborted by the software in your hosty machine.(10053)
unable to post a read for the command string,
sock error: Error = 10053"

I'm not sure if these errors are related.

The test code that I am trying to compile is the cxxpi.cxx code which I copied from the 32-bit installation files.

Cheers

Euan

Hi,

# Did you recompile your code after installing the 64-bit version of MPICH2 ?
# Did you install the 64-bit Visual studio SP1 runtime (http://www.microsoft.com/downloads/details.aspx?familyid=EB4EBE2D-33C0-4A47-9DD4-B9A6D7BD44DA&displaylang=en) ?

 Let us know the results.

Regards,
Jayesh

Hello,

I have been using the latest version of MPICH2 on a 32-bit windows OS with MS visual studio 2008 and I have recently converted to a 64-bit machine.

If I download the 32-bit version of MPICH2 my code successfully executes as before; however, if I then uninstall the 32-bit version and install the 64-bit version I can't get the same code to execute. The error message produced is:

"launch failed: CreateProcess(test_parallel_3.exe) on 'machine_name' failed, error 14001 - The application has failed to start because its side-by-side configuration is incorrect..."

As far as I can tell, mpiexec and smpd are both installed and working correctly. I think the problem is with Visual Studio. I have used the configuration manager to set the active solution platform to "x64" with the active solution configuration as "debug", but this doesn't seem to help. Has anyone else experienced this problem?

I would appreciate any help/advice.

Many Thanks

Euan
