[mpich-discuss] launch failed when debugging i VS2008, 32bit application on 64 bit platform, on W7

Mon Sep 27 10:57:11 CDT 2010

Hi,
 Can you try the "debugging property settings" below and let us know if it works for you,

# Remove "MPIRun arguments" property setting
# Remove "MPIRun Working Directory" project setting
# Remove "Application command" property setting.
# Remove "mpishim location" property setting

# Compile the MPI hello world program available at https://svn.mcs.anl.gov/repos/mpi/mpich2/trunk/examples/hellow.c (executable is hellow.exe).
# In "Cluster Debugger Configuration" set "Cluster head node" as "localhost" (without the quotes)
# In "Cluster Debugger Configuration" set "Number of processes" as "3" (without the quotes - to launch 3 MPI processes)

# Don't change the settings of "MPIRun Command", "Application Arguments", "MPI network security mode", "MPI network filter", "Debugger type" .

# Submit the project setting changes
# Set a breakpoint in the explorer window
# Press F5 to debug your code.

 Let us know the results.
 You might also want to refer http://msdn.microsoft.com/en-us/library/ee945376.aspx for information on how to debug MPI processes in VS 2008 .

Jayesh

Hi Jayesh.

The mpishim.exe is originally from
C:\Program Files\Microsoft Visual Studio 9.0\Common7\IDE\Remote Debugger\x86

I placed it in 
C:\Windows\System32

It used to work when I had the 32bit system, even without specifying the path.

The apc665 is the name of my computer. In the error message it actually states the full path+name of my computer in the network system, and it is ok. I only use nodes on my (local) computer. Is there other info you need?

When I try debugging the cpi solution, with the following debugging property page:

	Configuration: Active (Debug) 
	Platform: Active (Win32) 
	Debugger to launch: MPI Cluster Debugger 

	MPIRun Command: C:\Program Files (x86)\MPICH2\bin\mpiexec.exe
	MPIRun Arguments: -n 2 
	MPIRun Working Directory: C:\Program Files (x86)\MPICH2\examples
	Application Command: C:\Program Files (x86)\MPICH2\examples\cpi.exe
	Application Arguments: <empty>
	MPIShim Location: C:\Windows\System32\mpishim.exe 
	MPI network security mode: Accept connections from any address 
	MPI network filter: <empty> 
	Debugger type: Auto 

I get the same error message for both nodes:

launch failed: CreateProcess(C:\Windows\System32\mpishim.exe APC665 {<a long number>} " C:\Program Files (x86)\MPICH2\examples\cpi.exe") on ‘apc665.dhi.dk’ failed, error 2 – The system cannot find the file specified.

So, I wonder, is it mpishim, mpiexec or cpi which can't be found? I can't help thinking that I need some setting in Visual Studio. I hope the above gives you a clue?

Please let me know if you need more info of my setup.

Thanks for looking into this,

/Iris

Hi,
 Another thing to look for is if the path to mpishim.exe is correct.
 Do you have multiple network adapters in your machine. If so, try only enabling one of the adapters.
 Let us know the results.

Jayesh

Hi,
 Can you provide us some more details on your debug setup (eg: Is "apc665" the localhost ? etc)?
 Do you get the same error if you try to debug cpi.exe provided with the MPICH2 installation (c:\program files\MPICH2\examples\cpi.exe)?

Jayesh

Hi Jayesh,

Thanks a lot for your quick reply!

Yes, I tried also with the full path for the .in file (it is the same as the working dir) but no success.
I have used the MPI Cluster Debugger before, on windows vista 32 bit. When I reinstalled the Visual Studio 2008 on the windows7 64 bit machine, is it then the same debugger - does it work on both 32- and 64 bit code? Could it be the mpishim version? Or could it have something to do with the location of the Debug directories? I saw something about that in another ticket....I guess my understanding of how the debugger works is quite limited - I just use it!

Best regards,
Iris

Hi,
 Have you used the MPI cluster debugger before for debugging MPI applications built with MPICH2 ?

Jayesh

Dear list members, 

I recently changed to Windows7 64 bit platform. 

I reinstalled VisualStudio 2008 and SP1, along with IntelVisualFortran. 

I also reinstalled MPICH2 for 32 bit windows, because the mpi-application I want to debug is 32 bit. 

I have no trouble compiling and running the resulting executable outside VS2008. 

But when I want to debug in VS2008, I get an error. It used to work on 32 bit Windows Vista. 

This is the error notice, which comes for both processes (with my comments in <>): 

Launch failed: CreateProcess (C:\Windows\System32\mpishim.exe APCxxx {<a long number>} C:\Work\ns3\bin\ns3hs.exe caseA_reg1.in on ‘apc665’ failed, error 2 – The system cannot find the file specified. 

The settings in VS on the property page for debugging is: 

Configuration: Active (Debug) 

Platform: Active (Win32) 

Debugger to launch: MPI Cluster Debugger 

MPIRun Command: C:\Program Files (x86)\MPICH2\bin\mpiexec.exe 

MPIRun Arguments: -n 2 

MPIRun Working Directory: C:\projects\11802389-1_SeabedWindfarmInteraction\test_new_user\wave_3D_stokes\caseA_reg1_channel\input 

Application Command: C:\Work\ns3\bin\ns3hs.exe 

Application Arguments: caseA_reg1.in 

MPIShim Location: C:\Windows\System32\mpishim.exe 

MPI network security mode: Accept connections from any address 

MPI network filter: <empty> 

Debugger type: Auto 

I have searched for tickets of the same kind but haven’t found any. Do you know if there is any way I can get information on which file that can’t be found? Or what the problem is? Do I have some wrong files, or do I miss a setting in VS? Remember that the program compiles and can be run outside VS2008. 

(I have checked that the paths and file-names are ok!) 

I will be happy for any suggestion! 

Many thanks in advance, 

Iris
