Bruno,

it works in parallel with foamJob but it is very very very slow.

I think the problem is linked with something else.

I am not able to recompile the ThirdParty-1.6.x directory !

[111]cfs10-sanchi /shared/OpenFOAM/ThirdParty-1.6.x % ./Allclean
set: Variable name must begin with a letter.
[112]cfs10-sanchi /shared/OpenFOAM/ThirdParty-1.6.x % ./Allwmake
set: Variable name must begin with a letter.

Stephane.

Bruno,

yes I have run the 2 ways in the same terminal.

Hereafter is the error message with the following command :

Stephane,

I've got a feeling that the problem is linked to your Linux box. If I'm not mistaken, OpenFOAM assumes that the application sh is assumed to be the same as dash, thus the weird errors you got from Allwmake and Allclean.

orted: Command not found.

Additionally, also due to the Linux version you've got, the mpirun application found by foamJob and by the command line, are different!

So, I suggest trying to figure out who is seeing what... in other words:

• to know which sh are you using:

  ls -l `which bin`

• to know which mpirun are you using from the command line:

  ls -l `which mpirun`

• to know which mpirun foamJob is using:

  ls -l `findExec mpirun`

These should show you to whom those names are linked to and where they are.
By the way, I missed the findExec command the first time I looked at the code I believe it's an OpenFOAM script for finding its own applications.

Best regards,
Bruno

Hi,
the problem with Allwmake and Allclean is solved. I have switched between tcsh and bash.

ls: cannot access findExec:: No such file or directory
ls: cannot access command: No such file or directory

Do you mean findExec or foamExec ?

Looking at code in a lightning fast way tends to give bad results sometimes Sorry about that, findExec is a function in foamJob. It's a:

# replacement for possibly buggy 'which'

My guess is that this link to orterun doesn't work very well. You can check if that file really exists:

ls -l /shared/OpenFOAM/ThirdParty-1.6.x/openmpi-1.3.3/platforms/linux64GccDPOpt/bin/orterun

You better edit the foamJob script:

which foamJob

and go to the last lines and where is says:

echo "Executing: mpirun

change to

echo "Executing: $mpirun

Run foamJob like you have done before and now you will know who is foamJob really using!

Best regards,
Bruno

[openfoam_user]

Hi Bruno,

the link orterun exists !
ls -l /shared/OpenFOAM/ThirdParty-1.6.x/openmpi-1.3.3/platforms/linux64GccDPOpt/bin/orterun

As suggested I have changed mpirun to $mpirun into the foamJob script:

It is strange because:
the command which mpirun gives
/shared/OpenFOAM/ThirdParty-1.6.x/openmpi-1.3.3/platforms/linux64GccDPOpt/bin/mpirun

and the below command doesn't run :

Like I tried to guess before, for some wicked reason, the link from mpirun to orterun isn't being properly recognized. Could be a problem related to the Linux distribution+version you are using.

Well, there are various possible solutions at hand... you can try these two commands to run mpirun:

• Run the full command, like foamJob does:

  /shared/OpenFOAM/ThirdParty-1.6.x/openmpi-1.3.3/platforms/linux64GccDPOpt/bin/mpirun  -np 6 -hostfile machines /shared/OpenFOAM/OpenFOAM-1.6.x/bin/foamExec  interDyMFoam -parallel | tee log

• Switch to orterun instead of mpirun:

  orterun -np 6 -hostfile machines /shared/OpenFOAM/OpenFOAM-1.6.x/bin/foamExec  interDyMFoam -parallel | tee log

And/or you can try to fix the link that mpirun has:

• By copying orterun to mpirun:

  cp /shared/OpenFOAM/ThirdParty-1.6.x/openmpi-1.3.3/platforms/linux64GccDPOpt/bin/orterun /shared/OpenFOAM/ThirdParty-1.6.x/openmpi-1.3.3/platforms/linux64GccDPOpt/bin/mpirun

• Or by making a full link:

  unlink /shared/OpenFOAM/ThirdParty-1.6.x/openmpi-1.3.3/platforms/linux64GccDPOpt/bin/mpirun
  ln -s  /shared/OpenFOAM/ThirdParty-1.6.x/openmpi-1.3.3/platforms/linux64GccDPOpt/bin/orterun  /shared/OpenFOAM/ThirdParty-1.6.x/openmpi-1.3.3/platforms/linux64GccDPOpt/bin/mpirun

Best regards,
Bruno

[openfoam_user]

Hi Bruno,

Using the commands unlink and then ln -s doesn't work at all !

How it works :
1. Using foamJob -s -p interFoam
2. /shared/OpenFOAM/ThirdParty-1.6.x/openmpi-1.3.3/platforms/linux64GccDPOpt/bin/mpirun -np 4 -hostfile machines /shared/OpenFOAM/OpenFOAM-1.6.x/bin/foamExec interFoam -parallel | tee log

How it doesn't work :
1. mpirun -np 4 -hostfile machines /shared/OpenFOAM/OpenFOAM-1.6.x/bin/foamExec interFoam -parallel | tee log
orted: Command not found.
--------------------------------------------------------------------------

mpirun was unable to launch the specified application as it could not find an executable:

Executable: interFoam

while attempting to start process rank 2.
--------------------------------------------------------------------------

I would like to understand why, if possible.
In the past I have used the following command without problem :
mpirun -hostfile machines -np 4 interFoam -parallel > log

Was it in the very same machine? The very same linux box? Was it with the same OpenFOAM's OpenMPI version?
My guess is still what I've said before, and "unlink and then ln -s" not working are indicative that something just isn't working properly with the linking mechanism of your Linux installation.

Have you tried the copy possibility? Or did you copy first and then tried the linking possibility? I should have listed them in the opposite order... Because after copying, unlink is no longer applicable, since mpirun would no longer be a link!

Best regards,
Bruno

[openfoam_user]

Bruno,

Yes, I have run in parallel with OF-1.6.x. And at least with openSUSE 11.1. Now I have openSUSE 11.2.

Maybe this can help solve my problem.

That's because the OpenFOAM environment isn't working on the opened ssh shell, thus LD_LIBRARY_PATH doesn't have the necessary paths for mpirun to find the necessary libraries.

Like I've asked before, have you tried copying orted to mpirun?

By copying orted to mpirun:

cp /shared/OpenFOAM/ThirdParty-1.6.x/openmpi-1.3.3/platforms/linux64GccDPOpt/bin/orterun /shared/OpenFOAM/ThirdParty-1.6.x/openmpi-1.3.3/platforms/linux64GccDPOpt/bin/mpirun

Bruno,

I have copied *orted* to *mpirun*.

And now even the foamJob command does not work anymore.

Ah %#"#"!$ ... I'm sorry, something went very wrong with my memory It's orterun not orted
To fix it:

cp /shared/OpenFOAM/ThirdParty-1.6.x/openmpi-1.3.3/platforms/linux64GccDPOpt/bin/orterun /shared/OpenFOAM/ThirdParty-1.6.x/openmpi-1.3.3/platforms/linux64GccDPOpt/bin/mpirun

Or by making a full link:

rm /shared/OpenFOAM/ThirdParty-1.6.x/openmpi-1.3.3/platforms/linux64GccDPOpt/bin/mpirun
ln -s /shared/OpenFOAM/ThirdParty-1.6.x/openmpi-1.3.3/platforms/linux64GccDPOpt/bin/orterun /shared/OpenFOAM/ThirdParty-1.6.x/openmpi-1.3.3/platforms/linux64GccDPOpt/bin/mpirun

Or making the same relative link it use to have:

rm /shared/OpenFOAM/ThirdParty-1.6.x/openmpi-1.3.3/platforms/linux64GccDPOpt/bin/mpirun
ln -s orterun /shared/OpenFOAM/ThirdParty-1.6.x/openmpi-1.3.3/platforms/linux64GccDPOpt/bin/mpirun

Hopefully, either one of these should do the trick (maybe except the last solution). Once again, I'm sorry for the typo

I'm going to fix the other posts, just in case someone else tries to run those commands

Best regards,
Bruno

Hi Bruno,

I have installed version 1.7.0. I have run some tutorials (motorbike and mixer2D) in serial and it works.

But I can't run any case in parallel.

[wyldckat]

Hi Stephane,

Well, you changed OpenFOAM version, but not Linux version

OpenFOAM 1.7.0 right now is almost just like 1.6.x, except for a few tweaks and addons. So, try one of steps in my previous post, but this time don't forget it's:

• ThirdParty-1.7.0 and not ThirdParty-1.6.x;
• openmpi-1.4.1 and not openmpi-1.3.3!

Best regards,
Bruno

[openfoam_user]

Bruno,

no it doesn't work.

Always same error message.

foamJob -s -p doesn't neither.

Stephane.

[wyldckat]

OK, that Linux box doesn't seem to want to work with OpenMPI :P

Stephane do me a little favor and post what you get when you run this command:

ls -l  /shared/OpenFOAM/ThirdParty-1.7.0/openmpi-1.4.1/platforms/linux64GccDPOpt/bin

Without seeing some more clues of what the situation looks like, it'll be a lot harder to figure out what is going on!

And what comes out from these commands:

echo MPI_ARCH_PATH=$MPI_ARCH_PATH
echo OPAL_PREFIX=$OPAL_PREFIX
echo PATH=$PATH

Bruno

They changed places... honestly I haven't looked with much attention to OpenFOAM 1.7, although I've already built it in Ubuntu 9.10 without any issues...

OK, as for the problem you're getting... I'm getting kinda stumped as to what is going on The few things that come to mind are:

• The path /opt/mpich/bin in PATH could be conflicting with OpenMPI's binaries for same strange reason.
• Maybe there are other environment variables defined by default that are referent to MPICH and have names that OpenMPI also uses. The commands env or export should give you a list of all defined environment variables.
• Try running some kind of test with OpenMPI that isn't related to OpenFOAM. I know MPICH2 has a parallel pi calculation example, but I don't know if OpenMPI has anything like that with it.
• Have you tried running again the parallelTest application that OpenFOAM has in its test applications? But now with the 1.7 version!?
• What does foamJob output? Is it the same error? And how does it launch mpirun (or orterun or mpiexec)?

Best regards,

Hi Bruno,
The path */opt/mpich/bin* in *PATH* does not exist no more. But still does not run in parallel.

The *foamJob* output is :

[110]cfs10-sanchi /shared/sanchi/OpenFOAM/sanchi-1.6.x/Eole % foamJob -s -p MRFSimpleFoam
Parallel processing using OPENMPI with 4 processors
Executing: mpirun -np 4 -hostfile machines /shared/OpenFOAM/OpenFOAM-1.7.0/bin/foamExec MRFSimpleFoam -parallel | tee log
[111]cfs10-sanchi /shared/sanchi/OpenFOAM/sanchi-1.6.x/Eole %

The log file is empty.

With the *parallelTest* application the results is the same. The log file is empty.[110]cfsfs-sanchi /shared/sanchi/OpenFOAM/sanchi-1.6.x/Eole % foamJob -s -p parallelTest
Parallel processing using OPENMPI with 4 processors
