Creation of CA Parallel version (Ubuntu 16.04 / Code Aster 13.2.0)

nicorannou · 2016-11-08 19:26:00

Hello
I try to create a parallel release of CA but I get an error with the last command (./waf install -p, see https://sites.google.com/site/codeaster … 4-english). The error appears at the step 'build the elements catalog elem.1 using installed aster (from cata_ele.ojb)' and apparently I need ~30GB memory to overcome this step.

Does it mean that I need a machine with more than 30GB to generate a parallel version of CA?

There is probably another problem. Which version do you want to compile?

Regards

Mac

Hello
As you can see in the topic, the CA version to compile is 13.2.0.

Hello,

I think the origin of the problem is an incompatibility with MPI includes (mpi.h).
But I didn't yet search more for the moment...

Hello,

@nicorannou

Which version of openmpi are you using ?

$mpirun --version

Thanks

stephane

nicorannou · 2016-12-29 11:24:19

Hello @stephaneberger,

the mpi version installed on my machine is 1.10.2.

Hello,

Last code_aster compiles without error with openmpi-1.8.8.

The problem occurred since openmpi-1.10.0. I also check that it has not been "fixed" in last 1.10.5.

During the last stage of the build process, code_aster is called directly. If it is called code_aster through mpirun, it works as expected.

A temporary fix is to add:

   self.env['CATALO_CMD'] = 'mpirun'

in the 'configure' function in the file used via --use-config.

Another fix is simply to use openmpi 1.8 wrappers just by changing your PATH environment variables.

Hello Mr Courtois,

thanks a lot! Indeed, parallel CA is well compiled by adding :
self.env['CATALO_CMD'] = 'mpirun' in the configuration file.

So, I ran a job but an error occurs :

Sur les 4041 mailles du maillage MAIL, on a demandé l'affectation de 4041, on a pu en affecter 4041

Indeed, the fix will be to prepend the command with 'mpirun -np 1' (because without argument mpirun may start one process per existing core...).

@nicorannou: send a testcase to reproduce them problem.

nicorannou · 2017-01-13 22:40:02

Hello
here is testcase which shows the problem.
