Preliminary Exploration of mpich2 + vc6.0 package + win7 + 64-Bit Single-host platform command line operation

Recently, I was suddenly interested in MPI, but I had to take a few days to break down and feel depressed for a few days .. Today, we have made some breakthroughs, and we have entered the MPI gate ..

 

It should be noted that although it is a 64-bit platform, it also requires a 64-bit C compiler, and the conditions are a bit harsh. I only want to use 32-bit cl.exe. I don't think that 32-bit mpich2 is also feasible, which saves a lot of effort.

 

First download the latest mpich2:

Bytes.

 

Next, install it using the command line (recommended), and read the following email:

Hi, very thanks for your response.
I reinstalled the mpich2 by the steps that you say to me.
After the installation I try to run a non-MPI Program (mpiexec-N 2
Hostname) and I have the same error:
I have the output:
Please specify an authentication passphrase for SMPD:
I write the authentication passphrase and the system response to me:
Aborting: Unable to connect to user-PC
Very thanks.
I will thanks any help.

Look at the red part and you will know:

First, open the attachment, find the command prompt icon, right-click it, and choose to run it as an administrator (note that you must be granted the Administrator permission. This is also the heart of my past few days !!).

Run the msiexec command to uninstall or install the mpich2 package.

For example, The mpich2-1.2.1p1-win-ia32.msi file is placed under the root directory of the E disk

Msiexec/I E:/mpich2-1.2.1p1-win-ia32.msi so that you can complete the administrator permissions under the mpich2 installation, execute the installation process, only the default (PATH also do not change, so worry a lot) next step ,, ..

 

Then I wrote a program, which was provided by netizens and I did not change either:

 

# Define mpich_skip_mpicxx
# Include <MPI. h>
# Include <stdlib. h>
# Include <stdio. h>
# Include <conio. h>
# Include <math. h>
# Include <iomanip. h>
# Include <fstream. h>
# Include "string. H"
# Pragma comment (Lib, "MPI. lib ")

Int main (INT argc, char * argv [])
{
Int numprocs, rank, namelen;
Char processor_name [mpi_max_processor_name];

Mpi_init (& argc, & argv );
Mpi_comm_size (mpi_comm_world, & numprocs );
Mpi_comm_rank (mpi_comm_world, & rank );
Mpi_get_processor_name (processor_name, & namelen );
Printf ("process % d on % s out of % d/N", rank, processor_name, numprocs );

Mpi_finalize ();

Return 0;

}

Save as the Cl. c file ..

 

Then the compiling environment is ready:

If you want to use vs or Vc, you can use it. here we will create a new one, capture the vc6.0 package (use the bin include Lib in it), and obtain the following directory items:

 

The next step is to compile the. c file ..

 

It is convenient to write a batch:

 

@ Echo off
Set include = C:/program files (x86)/mpich2/include; D:/vcpack/mfc/include
Set Lib = C:/program files (x86)/mpich2/LIB; D:/vcpack/mfc/lib
Set Path = C:/program files (x86)/mpich2/bin; D:/vcpack/bin; % PATH %

Echo --------------- ======= by goldenspider 2010-7-25 ====== -------------------
Echo on

CL/C Cl. c

Link/libpath: "C:/program files (x86)/mpich2/lib" Cl. obj mpi. Lib

Del *. OBJ

Pause

Mpiexec-N 4 cl.exe

 

Save it as make. bat. Be sure not to run it by double-clicking. This is only executed under the user permission and must be executed under the Administrator permission .. The directory is as follows:

 

 

 

So we can use the above method to get the command prompt under the Administrator permission, and then switch to the directory where make. bat is located to run the make. BAT file. As follows:
