Multisphere Parallel

Hello all,

as I read in the newest release, it is now possible to calculate multisphere simulations with multicore processing.
So I updated the latest version and tried to simulate the multisphere example with mpirun -np 4 liggghts -in in.multisphere.
But it did not work.
Did I somehting wrong?

Public version

The in.multisphere file says:

"PUBLIC version only supports serial execution"

so, you can use :

processors 1 1 1 , with mpirun -np 1
processors 2 2 2 , with mpirun -np 8
processors 3 3 3 , with mpirun -np 27

Depending on the number of

Depending on the number of processors I got with this several different errors.
But as the release says :"Multi-sphere goes parallel: release of the parallel computation module for mult-sphere simulation"
It means a parallel execution is now available or is is not?

No problem for me

I have been able to run a multi sphere simulation using

processors 4 2 1

So, a total of 8 CPUs.
But the test was running a my input file, not the in.multisphere example.

Hi Westbrink,

what was the problem or error message?

Hi Christoph,

Hi Christoph,
attached you will find the error message.
Maybe it is due to the fact that I simulate a huge number of stl-meshes (>500). But with single-core processing it works fine.

Hi Westbrink,

>>Maybe it is due to the fact that I simulate a huge number of stl-meshes (>500). But with single-core processing it works fine.
I assume this might be the case. If you can provide a short, clean case (< 1 screen page) which shows the error in less than a minue, we can have a look before the next release!

thanks and best wishes
Christoph

Hello,

As Westbrink, I installed the last version of LIGGGHTS and tried to run the multisphere stone restitution exemple without success. Here the error message I get:

ERROR: Fix multisphere (id integr): Multisphere parallel execution is not available in your version. See www.cfdem.com for details (/build/liggghts-QCz4in/liggghts-3.3.1+repack1/src/fix_multisphere.cpp:300)
-------------------------------------------------------
Primary job terminated normally, but 1 process returned
a non-zero exit code.. Per user-direction, the job has been aborted.
-------------------------------------------------------
--------------------------------------------------------------------------
mpirun detected that one or more processes exited with non-zero status, thus causing
the job to be terminated. The first process to do so was:
Process name: [[49586,1],0]
Exit code: 1

Could it be a problem with the example file? I also tried for an input file I created but it didn't work either.

Thanks,

Succeed!

I had forgotten to modify the symbolic link when I re-installed the recent version of liggghts, so I continued to run the input file with the ancient compiler.

It works now.
