What is the outcome of this? I would really appreciate any help.

I have a similar issue on CentOS 7 with openmpi versions 4.0.0 and 1.6.5 to compile OpenFoam4.1.

Here I described what I did to get rid of the missing ptscotch.H file but this does not help me to use OpenFoam.

Segmentation fault with mpi

I attached my log.make file like you suggested in this thread:

v1606+ Compilation error - ptscotch.h not found

I also had a look at:

ThirdParty-3.0.x

My mpiexec and gcc seem good enough.

mpiexec --version
mpiexec (OpenRTE) 4.0.0

gcc --version
gcc (GCC) 4.8.5 20150623 (Red Hat 4.8.5-36)

I could not find tipps on installing OF4.1 for Centos 7 only for Centos 6.8.

Quick answer: Open-MPI 4.0.0 is way too recent to be using it with the old versions of OpenFOAM 4.1 and Scotch 6.0.3.

So please first confirm if you were able to build with Open-MPI 1.6.5 or whichever version that comes with CentOS 7.

Hi Bruno,

thank you for the suggestion.

I am able to build OF4.1 on CentOS 7 with the following Open-MPI Versions:

1.6.5
1.10.7
2.1.5
3.1.3

I cannot build it with

4.0.0.


I have not tried other versions. I was not able to determine the original version that comes with CentOS 7.

There is a problem with OF4.1 built by 3.1.3. Cases which usually run are now crashing.

[27] --> FOAM FATAL IO ERROR:
[27] wrong token type - expected Scalar, found on line 0 the word 'nan'

[27] file: myPATH/processor27/system/data.solverPerformance.p at line 0.

[27]     in file lnInclude/Scalar.C at line 93.
[27]
FOAM parallel run exiting

When I source Open-MPI 4.0.0 with the builded OF4.1 by 3.1.3 the cases are running.

Since I do not like running OF build by 3.1.3 and run with 4.0.0 I will use OF4.1 compiled and run (sourced) with Open-MPI 1.10.7.

Quick answers:

1. Open-MPI 3.1.3 is probably a big no-no, given that 3.1.1 and 3.1.2 have a critical bug in ti, as reported here: https://bugs.openfoam.org/view.php?id=3071
2. Likewise, 2.1.5 is a big NO as well, see the same report...
3. Open-MPI 1.6.5... that's very strange, because I've used that at the office without problems... even with OpenFOAM 5.x...
4. It is preferable to use Open-MPI 1.10.7, if you can use it without problems, given that it's the closest version to the one they reported as the version they tested with for OpenFOAM 4: https://github.com/OpenFOAM/ThirdParty-4.x/#openmpi
5. Open-MPI 4.0.0 is way too much of a new version; the probability of having critical bugs in it are fairly high, given that it's the very first version of a new series. You should only try to use it if you are trying to do some performance tests, in which case you should also use OpenFOAM-dev or at least OpenFOAM 6, both building from source code from the latest git repository.

Hi Bruno,

your post made me try to compile OF4.1 with open-MPI 1.6.5 again.

I was able to compile it with the versions

1.6.5
1.10.7
2.1.5
3.1.3

Hence 1.6.5 is working. I probably sourced the wrong path when I tried to compile OF4.1 with 1.6.5 and 2.1.5.

Thanks!

Hi Lukas,


Could you tell me how you compiled OpenFOAM with your locally compiled OpenMPI on the cluster?



I've been trying to do the same without much success (anymore).

[lukasf]

Hi,


which OpenFOAM version on which operating system are we talking about?


Which OpenMPI Versions are available on your system?
