Installation OpenFOAM-1.7.x with wmakeScheduler

Hey I am Tobi and a new community member,

first of all. Hello everybody.

I am working with Ubuntu 10.04 an had installed OpenFoam 1.7.1 with the Ubuntu/Debian Pack without problems.

So a good CFD - eng said, that the only version is up to date is the git responsitory.

I had downloaded everything and did all steps in the introductions.
Got so much mistakes and issues with compiling OpenFoam, but hope i have fixed it now. The only thing i can 't fix until now is using wmakeScheduler for compiling OF with my two cores :/

-> export WM_SCHEDULER=wmakeScheduler
-> export WM_HOSTS="shorty:2"
-> export WM_NCOMPPROCS=$($WM_SCHEDULER -count)

after typing echo $WM_NCOMPPROCS I got --> 2

After starting ./Allwmake it will stop at the beginning of line

"SOURCE=..."
"SOURCE=..."

what did i wrong? Sorry but i am new on Ubuntu - Distributions and so on.

Hope someone can help me. Couse i need the new Solver added in the new update.

Thanks
Tobi

Greetings Tobi and welcome to the forum!

Mmm, they should really put up a warning that for single machines, the wmakeScheduler isn't necessary. You can simply just do:

Code:

export WM_NCOMPPROCS=2

Or equal to the number of cores that your machine has. The other two variables aren't necessary.

edit: Wait... but WM_NCOMPPROCS did get set properly, since you said that 'export WM_HOSTS="shorty:2"' !! There was nothing wrong there, as far as I can tell!

Additionally, there are a few packages that you'll need to install to ensure that OpenFOAM will build: Building OpenFOAM1.7.0 from source post #4 and onward
In that thread you'll find the packages needed for building OpenFOAM and the code documentation (a few posts down).

Finally, to keep a log of the building process, run Allwmake like this:

Code:

./Allwmake > make.log 2>&1

You might need it after it's done, since something could go wrong :(

Best regards and good luck!

Hi Bruno,

I have read your thread that you have linked above a hour befor and added all the packages. Think that was my real problem to compile it without issues.

Just, i compile with 1 core :/ although i set WM_NCOMPPROS=2
Don 't know why it don' t work.

Will install OF on my new computer in three day's (6 cores)
I will test it with your Code

Code:

./Allwmake > make.log 2>&1

Thx for answering :)
Couse i need the chtMultiRegionLiquidFoam solver :)

Ooooo, so close... but if you really used that name, it's no wonder it didn't work :( It's:

Code:

export WM_NCOMPPROCS=2

You missed a C before the last S :(

If you want a more self-adapting code for setting that variable, you can use this:

    if [ -r /proc/cpuinfo ]

    then

        WM_NCOMPPROCS=$(egrep "^processor" /proc/cpuinfo | wc -l)

        [ $WM_NCOMPPROCS -le 8 ] || WM_NCOMPPROCS=8

    else

        WM_NCOMPPROCS=1

    fi



    echo "Building on $WM_NCOMPPROCS cores"

Add it to OpenFOAM's bashrc file, or to your own "~/.bashrc" file :)

Best regards,
Bruno

:) no I got the right var. Why it don 't work - don 't know.
Will try your last post and set it into my .bashrc.

Thx. Will make an answer how it work.

Tobi	October 25, 2010 03:44

Okay :)

OpenFoam-1.7.x (git) is now working (jehaaa) (:

if i install it on my new machine i will try to set the "WM_HOSTS" variable to

Code:

export WM_HOSTS="localhost:6"

Maybe this will work.

Greetings Tobi

Hey again,

included your code to my ~/.bashrc

Code:

shorty@shorty:~/OpenFOAM/OpenFOAM-1.7.x$ . $HOME/.bashrc

Building on 2 cores

shorty@shorty:~/OpenFOAM/OpenFOAM-1.7.x$ ./Allwmake

But he worked just with 1 core. Don 't understand why.
Got Ubuntu 10.04. A CFD-eng. said today, that the compiling with more cores doen 't work. He has linux and there it works but on his ubuntu don 't work the Scheduler.

I tested everything. If i build on 2 cores he is working until that code end

Code:

Hmm :/

Any ideas ?

Can make a log if this will help.

Hi Tobi,

Only when building libscotch and OpenMPI, it will only use a single core (the people at OpenCFD forgot about it :( ).

What does this output:

Code:

egrep "^processor" /proc/cpuinfo | wc -l

Additionally, are you building in a real or virtual machine?

-------------------- EDIT:
I think I figured it out - run this:

Code:

echo $HOST

If nothing outputs, then that is the problem! wmakeScheduler assumes that this variable exists, but apparently it depends on the Linux distribution used.
Try running this before you run Allwmake:

Code:

export HOST=$HOSTNAME

And use:

Code:

export WM_HOSTS="$HOSTNAME:6"

Instead of localhost!
Otherwise, you will have to make your ssh sessions passwordless. For example: How to connect with ssh without using a password

EDIT2: Ironically, this has already been fixed a few days ago in OpenFOAM 1.7.x.

Best regards,
Bruno

Hi Bruno,

first of all. Thx for your help.
I 'll got a new mainboard etc. so I have to wait until all is received.

And then I install everything new.

Question: Ubuntu 10.04 or CAE Linux Ubuntu 10.04?

After the installation i will check out your commands and post the output here.

Your question, if i build in a real or virtual machine, i think a real :( but I am not sure what you mean.

Build on my personal computer so i think its real.

Hope my english skills aren 't as bad as i think :(

Best reguards.
Tobi

PS: Think i will start compiling at saturdays.
