Dear Sir,

Now I want GPU Plugin for OpenFOAM 2.1.x
I have downloaded SpeedIT Classic toolkit from this link http://speedit.vratis.com/index.php/...d.html#content
but here it is not mention here for which OpenFOAM version this toolkit we can use.
where it will support OpenFOAM 2.1.x

Thanks
nagendra

Dear Sir,

I am Installing GPU Plugin for OpenFOAM name is 1.2 Classic.
In first step written like
Go to your path for FOAM applications

cd $WM_PROJECT_USER_DIR

But when I am running command cd $WM_PROJECT_USER_DIR
Its giving
cd: /home/others/trainee/OpenFOAM/trainee-2.1.x: No such file or directory
In etc/bashrc file
export WM_PROJECT_USER_DIR=$HOME/$WM_PROJECT/$USER-$WM_PROJECT_VERSION
while I am writing echo $WM_PROJECT_USER_DIR
/home/others/trainee/OpenFOAM/trainee-2.1.x
but there is no trainee-2.1.x directory.
I think need to create trainee-2.1.x directory in /home/others/trainee/OpenFOAM/.

Thanks

Hi Nagendra,

Sorry, I've never used the SpeedIt plugin, so I don't know how it works. But I do have some limited experience with Symscape's GPU plug-in: http://www.symscape.com/gpu-1-0-openfoam

The detail is that you will need to build the Single Precision version of OpenFOAM, instead of the default Double Precision.

There is also Cufflink, but it only works with Extend's variant of OpenFOAM named 1.6-ext: http://code.google.com/p/cufflink-library/


But is the GPU plug-in critical to your work? Because it is still very limited and only in some cases will you be able to draw any performance improvements :( At least AFAIK...

Best regards,
Bruno

Dear Sir,


On echo $WM_PROJECT_USER_DIR giving
/home/others/trainee/OpenFOAM/trainee-2.1.x
but there is not any directory trainee-2.1.x
cd $WM_PROJECT_USER_DIR giving
cd: /home/others/trainee/OpenFOAM/trainee-2.1.x: No such file or directory

echo $FOAM_USER_LIBBIN
/home/others/trainee/OpenFOAM/trainee-2.1.x/platforms/linux64Gcc44DPOpt/lib
cd $FOAM_USER_LIBBIN giving
cd: /home/others/trainee/OpenFOAM/trainee-2.1.x/platforms/linux64Gcc44DPOpt/lib: No such file or directory

while lib directory available in
~/OpenFOAM/ThirdParty-2.1.x/platforms/linux64Gcc44DPOpt$cd lib/

why these things happening.

Thanks
nagendra

Hi Nagendra,

Sorry about that, I didn't see the other details you had posted.
The reason why you're getting those error messages is because:

1. You haven't done the tutorials first: http://www.openfoam.org/docs/user/tu...s.php#x4-30002
   
   Quote:

   They can be easily copied by typing: Code: mkdir -p $FOAM_RUN cp -r $FOAM_TUTORIALS $FOAM_RUN

2. The folders "$FOAM_USER_APPBIN" and "$FOAM_USER_LIBBIN" are usually created only when you build a personal build of an OpenFOAM based application. For example, if you follow these instructions: http://openfoamwiki.net/index.php/Ho...ure_to_icoFoam

Best regards,
Bruno

Dear Sir,

I have followed upto step-6 on running command
my_icoFoam

I am getting FOAM FATAL ERROR.
and one more thing $FOAM_USER_LIBBIN did not create.
cd $FOAM_USER_LIBBIN
cd: /home/others/trainee/OpenFOAM/trainee-2.1.x/platforms/linux64Gcc44DPOpt/lib: No such file or directory

I am attaching make.log file for my_icoFoam command.


Thanks
nagendra

Hi Nagendra,

Sorry about that, I forgot to mention that the example for adding temperature to icoFoam usually only creates the "$FOAM_USER_APPBIN" folder, because it creates only an application.

Nonetheless, if you do want to create the last remaining folder, you can simply run:
But keep in mind that only personally built libraries will be placed in there.

Best regards,
Bruno
