hi
I run my case in 1core without any error but when I run with mpirun I face this error:

./Allrun

--> FOAM FATAL ERROR:
Trying to use the dummy Pstream library.
This dummy library cannot be used in parallel mode

From function UPstream::init(int& argc, char**& argv)
in file UPstream.C at line 37.

FOAM exiting



--> FOAM FATAL ERROR:

-----------------------------------------------------------------------------
It seems that [at least] one of the processes that was started with
mpirun did not invoke MPI_INIT before quitting (it is possible that
more than one process did not invoke MPI_INIT -- mpirun was only
notified of the first one, which was on node n0).

mpirun can *only* be used with MPI programs (i.e., programs that
invoke MPI_INIT and MPI_FINALIZE). You can use the "lamexec" program
to run non-MPI programs over the lambooted nodes.
-----------------------------------------------------------------------------

I do this but not work:

cd $FOAM_LIBBIN
mv dummy/ dummy__
and
cd $FOAM_SRC
cd Pstream
./Allwmake

I do this but not work:

Code:
echo "$WM_PROJECT_DIR/etc/bashrc"
Find the line that says:
Code:
export WM_MPLIB=OPENMPI
Change it to:
Code:
export WM_MPLIB=SYSTEMOPENMPI
Start a new terminal and try again running the application in parallel.
If it still has problems, go to OpenFOAM's folder and run Allwmake once again:
Code:
cd $WM_PROJECT_DIR ./Allwmake > make.log 2>&1

Hi Hadi,

It looks like you have an incomplete system installation.
What Linux Distribution are you using and which installation instructions did you follow?

Best regards,
Bruno

[dark lancer]

OpenFOAM2.1.1
suse 12.3
I use this installation instructions

openSUSE 12.2

http://openfoamwiki.net/index.php/In...2.1.1/openSUSE

Hi Hadi,

What do the following commands give you:

echo $WM_MPLIB
echo $FOAM_MPI_LIBBIN
mpirun --version

Edit the file "$HOME/.bashrc" and tell me what are the last lines you have got that relate to OpenFOAM.

Best regards,
Bruno

I give this result:

                                processes to <dir>
                -x <envlist>    Export environment vars in <envlist>

Nodes:          n<list>, e.g., n0-3,5
CPUS:           c<list>, e.g., c0-3,5
Extras:         h (local node), o (origin node), N (all nodes), C (all CPUs)

Examples:       mpirun n0-7 prog1
                Executes "prog1" on nodes 0 through 7.

                mpirun -lamd -x FOO=bar,DISPLAY N prog2
                Executes "prog2" on all nodes using the LAMD RPI.  
                In the environment of each process, set FOO to the value
                "bar", and set DISPLAY to the current value.

                mpirun n0 N prog3
                Run "prog3" on node 0, *and* all nodes.  This executes *2*
                copies on n0.

                mpirun C prog4 arg1 arg2
                Run "prog4" on each available CPU with command line
                arguments of "arg1" and "arg2".  If each node has a
                CPU count of 1, the "C" is equivalent to "N".  If at
                least one node has a CPU count greater than 1, LAM
                will run neighboring ranks of MPI_COMM_WORLD on that
                node.  For example, if node 0 has a CPU count of 4 and
                node 1 has a CPU count of 2, "prog4" will have
                MPI_COMM_WORLD ranks 0 through 3 on n0, and ranks 4
                and 5 on n1.

                mpirun c0 C prog5
                Similar to the "prog3" example above, this runs "prog5"
                on CPU 0 *and* on each available CPU.  This executes
                *2* copies on the node where CPU 0 is (i.e., n0).
                This is probably not a useful use of the "C" notation;
                it is only shown here for an example.

Defaults:       -c2c -w -pty -nger -nsigs

Quick answer: The problem is that your system's MPI is actually MPICH2. For that, follow the instructions given here: http://www.cfd-online.com/Forums/ope...tml#post383090 post #9

Hi Hadi,

Now I'm the one confused on what exactly you want to do here

OK, first let's do some clean up:

1. Change this:
   

   Originally Posted by dark lancer

   #export PILOTRATE=115200
   
   test -s ~/.alias && . ~/.alias || true
   source /home/hadi/OpenFOAM/OpenFOAM-2.1.1/etc/bashrc WM_NCOMPPROCS=7 WM_MPLIB=SYSTEMOPENMPI
   source /home/hadi/OpenFOAM/OpenFOAM-2.1.1/etc/bashrc WM_NCOMPPROCS=7 WM_MPLIB=SYSTEMOPENMPI

   export LD_LIBRARY_PATH=/usr/lib/mpi/gcc/openmpi/lib
   
   source /opt/intel/bin/compilervars.sh intel64
   
   source /home/hadi/OpenFOAM/OpenFOAM-2.1.1/etc/bashrc WM_NCOMPPROCS=7 WM_MPLIB=SYSTEMOPENMPI
   source /home/hadi/OpenFOAM/OpenFOAM-2.1.1/etc/bashrc WM_NCOMPPROCS=7 WM_MPLIB=SYSTEMOPENMPI

2. To this:
   

   #export PILOTPORT=/dev/pilot
   #export PILOTRATE=115200
   
   test -s ~/.alias && . ~/.alias || true
   
   #export  PATH=${PATH}:${HOME}/bin:/opt/intel/bin:/opt/mpich2-install/bin:/home/moosaie/programs/ParaView-3.14.1-Linux-64bit/bin/
   
   export PATH=${PATH}:${HOME}/bin:/opt/intel/bin:/home/moosaie/programs/ParaView-3.14.1-Linux-64bit/bin/
   
   export LD_LIBRARY_PATH=/usr/lib/mpi/gcc/openmpi/lib
   
   source /opt/intel/bin/compilervars.sh intel64
   
   source /home/hadi/OpenFOAM/OpenFOAM-2.1.1/etc/bashrc WM_NCOMPPROCS=7 WM_MPLIB=SYSTEMOPENMPI

   Notice that I removed the extra source command lines you had for OpenFOAM. One at the end is enough.
   In addition, I removed the reference to "/usr/bin/mpicc", because that's an executable file, not a folder.

Now, let's try and get something clear here: what MPI toolboxes do you have installed in your system and which one do you want to use?


Best regards,
Bruno

I change to this:

A long time ago install mpich2 on suse 12.2 and update to 12.3 and now I install OpenFOAM2.1.1 on suse 12.3 now I run my case with this command:

./Allrun

I face error that explain in the perviouse posts

I use mpirun and I don't now what do you mean form this''what MPI toolboxes do you have installed in your system and which one do you want to use?''?

[wyldckat]

Hi Hadi,

OK, I'll try to explain this simply. From the information you are providing, it looks like you have 3 MPI toolboxes in your machine:

1. MPICH2
2. Open-MPI
3. Intel MPI

The executable "mpirun" exists in all 3 toolboxes.
My question is which MPI toolbox you want to use, because you cannot have all 3 versions working at the same time in the same shell environment.


I suggest that you study the following blog post, as well as the links it provides: Advanced tips for working with the OpenFOAM shell environment

Best regards,
Bruno

[dark lancer]

hi Bruno and thanks for all

I want to use Open-MPI for OpenFOAM because I think Open-MPI set with OpenFOAM and Intel MPI I think but I'm not sure use for intel fortran that exist on system
We have a code of fortran that when we decide run it by parallel use MPICH2
and now I must uninstall MPICH2 that Open-MPI work and I don't know how to uninstall MPICH2??

a question??
this case is test???

Searching a little in the internet, I've found out that "--showme:compile" and "--showme:link" are Open-MPI options only. To change that to work with MPICH2, I've had to edit "/opt/openfoam211/etc/config/settings.sh" file and exchange "mpicc --showme:compile" and "mpicc --showme:link" for "mpicc -compile-info" and "mpicc -link-info".

if I can set OpenFOAM with MPICH2 is very good because We can run fortran and OpenFOAM together.

Hi Hadi,

I haven't tested the following steps, but it should work:

1. Edit the "~/.bashrc" file and change this line:
   

   source /home/hadi/OpenFOAM/OpenFOAM-2.1.1/etc/bashrc WM_NCOMPPROCS=7 WM_MPLIB=SYSTEMOPENMPI

   to this:
   

   source /home/hadi/OpenFOAM/OpenFOAM-2.1.1/etc/bashrc WM_NCOMPPROCS=7 WM_MPLIB=MPICH

2. Edit the file "etc/config/settings.sh" and search for this block of code:
   

   MPICH)
       export FOAM_MPI=mpich2-1.1.1p1
       export MPI_HOME=$WM_THIRD_PARTY_DIR/$FOAM_MPI
       export MPI_ARCH_PATH=$WM_THIRD_PARTY_DIR/platforms/$WM_ARCH$WM_COMPILER/$FOAM_MPI
   
       _foamAddPath    $MPI_ARCH_PATH/bin
   
       # 64-bit on OpenSuSE 12.1 uses lib64 others use lib
       _foamAddLib     $MPI_ARCH_PATH/lib$WM_COMPILER_LIB_ARCH
       _foamAddLib     $MPI_ARCH_PATH/lib
   
       _foamAddMan     $MPI_ARCH_PATH/share/man
       ;;

3. Change that block to this:
   

   MPICH)
       # Use the system installed MPICH2, get library directory via mpicc
       export FOAM_MPI=mpich2
   
       libDir=`mpicc -link-info | sed -e 's/.*-L\([^ ]*\).*/\1/'`
   
       # Bit of a hack: strip off 'lib' and hope this is the path to MPICH2
       # include files and libraries.
       export MPI_ARCH_PATH="${libDir%/*}"
   
       _foamAddLib     $libDir
       unset libDir
       ;;

4. Start a new terminal window.
5. Build OpenFOAM:
   

   foam
   ./Allwmake > make.log 2>&1

If everything goes well, at the end of the build, it should have everything working as intended.

Best regards,
Bruno

after it in new terminal go to this direction

cd OpenFOAM/OpenFOAM2.1.1

then

./Allwmake > make.log 2>&1

when finished I use

./Allrun

but

It seems that there is no lamd running on the host 172-15-2-53.

This indicates that the LAM/MPI runtime environment is not operating.
The LAM/MPI runtime environment is necessary for the "mpirun" command.

Please run the "lamboot" command the start the LAM/MPI runtime
environment. See the LAM/MPI documentation for how to invoke
"lamboot" across multiple machines.

It seems that [at least] one of the processes that was started with
mpirun did not invoke MPI_INIT before quitting (it is possible that
more than one process did not invoke MPI_INIT -- mpirun was only
notified of the first one, which was on node n0).

mpirun can *only* be used with MPI programs (i.e., programs that
invoke MPI_INIT and MPI_FINALIZE). You can use the "lamexec" program
to run non-MPI programs over the lambooted nodes.

Hi Hadi,

Well, at least it's looking like you're closer to solving this. The problem here is that the MPICH2 service - which responsible for coordinating the communications between the parallel processes - is not running.

How do you launch in parallel the FORTRAN programs that have been built with MPICH2?

Best regards,
Bruno

PS: Please follow the instructions given on the second link on my signature, namely as to how to post code and application outputs here on the forum. The idea is that the correct way is to use [CODE] and not [QUOTE].

Hi Hadi,

OK, I noticed that you updated your post.

Try this:

echo export WM_MPLIB=MPICH > $WM_PROJECT_DIR/etc/prefs.sh

Now try running mpirun again.

Best regards,
Bruno
