Hi,

I'm sorry for opening another issue, but I'm not able to understand why there is a segmentation fault when launching some examples. I tried to ran different examples always obtaining the following message (in this particular case I am running this example https://github.com/kibaekkim/DSPopt.jl/blob/0812121ea8031c3f67a8cf93a8f59ecdfe0ba897/examples/farmer_mpi_stoc.jl):

Segfault
Segfault1

Am I doing something wrong?

Thank you for your help

I will run the example on a linux machine. Did you run the example with mpiexec?

Thank you.

Yes I'm just running the example with julia (version 1.5.4) where I included the package MPI (version 0.16.1) but I don't think the problem is the package MPI because I also tried examples without this package and I obtained the same error.

I don't know if this can be helpful but here's what I recive when I try to run the example written on the README file (without the use of MPI and without considering the quadratic costraints) with julia:

Segfault
Segfault1

Again, thank you very much for your help, I'm really sorry for bothering you.

By making more analysis I was able to find that the problem is given by the line

using DSPopt

I don't know why, but if I use only StructJuMP and I try to build a model, all seems to work. If I simply add using DSPopt (without changing anything in the program, thus without making any optimization) appears the above message from the line

signal (11): ...

I have tried to remove and reinstall the packages but nothing changed.

I was not able to reproduce the segfault. Can you please provide more information in order to reproduce the error?

FYI, this is my testing environment.

This thing is really strange. I'm not able to understand where it comes from.

If I try to run the program in the same way you did, the following message appears:

It seems like I'm able to run the optimization but it ends in a wrong way.

In your example farmer_test.jl, you probably did not use or initialize MPI.jl, if you mean to run in parallel. Please see the example (https://github.com/kibaekkim/DSPopt.ja/blob/master/examples/farmer_mpi_stoc.jl#L6-L9). I may be able to say more if you share with me your example farmer_test.jl.

For the results from test DSPopt, you must have not build DSP with SCIP. Building with SCIP is optional but disables some algorithmic features (e.g., Benders decomposition).

Yes, thank you. Both your observations are correct. I removed the line using MPI in order to try understanding the problem and then I forgot to re-add it.

So do you think that the segmentation fault is caused by the fact that I built DSP without SCIP or is it something different?

No, I don't think so because I also built and tested the code without SCIP. It is interesting that the segfault occurred at the end of the code.

You built DSP with MPICH 3.3.2. Do you know if MPI.jl is using the same library? By default, MPI.jl does not use your system library. Please see https://juliaparallel.github.io/MPI.jl/stable/configuration/#Building You need to build MPI.jl again with the environment variable value set:

ENV["JULIA_MPI_BINARY"]="system"
] build MPI

Yes I built MPI following those guidelines. At this point I think there's something wrong in my configuration of Julia. Thank you very much for your help, I'll let you know if I'll be able to understand something more.
