Using Windows HPC MPI from c++ in SUA?

Fri, 03 Oct 2008 15:01:04 Z

Hello,

I am trying to use the Windows HPC MPI library from c++ using windows SUA.
So i am pretty new to this

Here is my simple c++ example:

#include <iostream> 
using namespace std; 
 
int main(){ 
   cout << "Hello World!\n"; 
   return 0 
} 

Compiled and ran it like this:

bash-3.2$ cc -o main.exe main.cpp 
bash-3.2$./main.exe 
Hello World! 
bash-3.2$ 

All looking good so far.

Now i want to include the mpi.h, here is my simple example:

#include <stdlib.h> 
#include <iostream> 
#include <mpi.h> 
 
using namespace std; 
 
static int mypid;       // PID of *this* node 
static int nnodes;      // number of nodes 
 
int main(int argc, char *argv[]) 
{ 
    cout << "Starting..." << endl; 
 
    // fire up MPI 
    cout << "call MPI_Init().." << endl; 
    MPI_Init(&argc, &argv); 
    MPI_Comm_rank(MPI_COMM_WORLD, &mypid); 
    MPI_Comm_size(MPI_COMM_WORLD, &nnodes); 
 
    // this test required two nodes 
    cout << "Rank " << mypid << " of " << nnodes << endl; 
 
    // clean up and exit 
    cout << "Clean up and exit..." << endl; 
    MPI_Finalize(); 
    return(0); 
} 

Now here is where i get confused, if i try to compile this i get this error:

bash-3.2$ cc -o simplempi.exe simplempi.cpp 
C:\Users\Administrator\mpiTest\simplempi.cpp(7) : fatal error C1083: Cannot open 
 include file: 'mpi.h': No such file or directory 
bash-3.2$ 

Which is ok as there is not an mpi.h for SUA. Now i would like to use the HPC mpi.h.
I downloaded and installed the HPC SDK pack (now i get the header files i need)

bash-3.2$ ls -al  "/dev/fs/C/Program Files/Microsoft HPC Pack 2008 SDK/Include/" 
total 312 
drwxrwx---+ 1 +SYSTEM  +SYSTEM      0 Oct  3 08:33 . 
drwxrwx---+ 1 +SYSTEM  +SYSTEM   4096 Oct  3 08:33 .. 
-rwxrwx---+ 1 +SYSTEM  +SYSTEM  13674 Sep  2 15:12 job-v2.xsd 
-rwxrwx---+ 1 +SYSTEM  +SYSTEM  47551 Sep 11 14:51 mpi.f90 
-rwxrwx---+ 1 +SYSTEM  +SYSTEM  53132 Sep 11 14:51 mpi.h 
-rwxrwx---+ 1 +SYSTEM  +SYSTEM  15750 Sep 11 14:51 mpif.h 
-rwxrwx---+ 1 +SYSTEM  +SYSTEM  18153 Sep 11 14:51 mpio.h 
-rwxrwx---+ 1 +SYSTEM  +SYSTEM   6466 Sep  2 15:12 task-v2.xsd 
bash-3.2$ 

I then tried to link these headers to my /usr/include (symbolic) (Maybe this is where i am going wrong??)

bash-3.2$ ln -s "/dev/fs/C/Program Files/Microsoft HPC Pack 2008 SDK/Include/"* /usr/include/ 
 

Then tried to recompile, it attempts to load the mpi.h file but has trouble reading it.???
I tried mixed mode and g++/cc89/cc but without any luck

bash-3.2$ cc -o simplempi.exe simplempi.cpp 
flip: /tmp/cc_tmp3_1117 is a binary file, not converted

bash-3.2$ 

So... I guess my question now is , is it possible?

Has anyone out there got an MPI example that works with the windows mpi.h from SUA?
Can anyone see something wrong in the way i am approaching this problem?

Any help is very gratefully received!

Regards
Steven

Hi, I apologize for no one getting back to you on this. We have a renewed effort in the forums so questions don't go un-answered now. But part of 'starting fresh' is to close out old posts that haven't been touched recently. Since things can change so quickly it is likely that many of the problems / questions that were posed several months ago have already been addressed in some other way.

I'm going to mark this thread as 'answered' to close it out. If you still have issues / questions please start a new thread with the updated information so that we can get to it.
