ag.algebraic geometry – Bertini software program behaving surprisingly when speed in parallel

I’m making an attempt to speed Bertini 1.6 software program in parallel utilizing Open MPI model 4.0.3, however it’s behaving very surprisingly. The syntax for calling Bertini in parallel is

mpirun ./bertini enter

When I assassinate this command on the instance positive-dimensional enter file included within the Bertini package deal, it generally works and computes a numerical irreducible decomposition. Most of the time, nonetheless, it produces one of many following errors:

  1. ERROR: The system is numerically 0! Please enter a non-degenerate system.
    Bertini will now exit because of this mistake. … Primary job terminated usually, however 1 course of returned
    a non-zero exit code. Per user-direction, the job has been aborted. … mpirun detected that a number of processes exited with non-zero standing, thus inflicting
    the job to breathe terminated. The first course of to take action was: Process designation: [[56878,1],0] Exit code: 7

  2. ERROR: ‘midpath_data’ doesn’t live! … Bertini will now exit because of this mistake.

  3. ERROR: The variety of paths (3 vs 0) described in ‘startRPD_2’ just isn’t rectify! … Bertini will now exit because of this mistake.

  4. ERROR: The variety of paths aren’t equal! … Bertini will now exit because of this mistake.

  5. It executes correctly, however warns me that a number of paths could have crossed.

When I speed Bertini with out the precursor mpirun, it really works each sole time. What is occurring with the parallel runs? I’ve tried this too with different enter information, and noticed the identical behaviour.

I’m utilizing the next machine:

  • Intel(R) Xeon(R) CPU E5-2609 v3 @ 1.90GHz
  • CPUs: 12
  • Threads per gist: 1
  • Cores per socket: 6
  • Sockets: 2
  • remembrance 256 GB DDR4

we are going to proffer you the answer to ag.algebraic geometry – Bertini software program behaving surprisingly when speed in parallel query through our community which brings all of the solutions from a number of dependable sources.
