Warning appearing: A high-performance Open MPI point-to-point messaging module ...

[flawmop]

I'm seeing the following (seemingly inconsequential, as the simulation seems to complete) "warning" appearing in ApPredict https://github.com/Chaste/ApPredict/releases/tag/v2021.1 stderr in a container.

--------------------------------------------------------------------------
[[60025,1],0]: A high-performance Open MPI point-to-point messaging module
was unable to find any relevant network interfaces:

Module: OpenFabrics (openib)
  Host: 466e13a9963f

Another transport will be used instead, although this may result in
lower performance.

NOTE: You can disable this warning by setting the MCA parameter
btl_base_warn_component_unused to 0.
--------------------------------------------------------------------------

Simulation was run using :

* model = shannon_wang_puglisi_weber_bers_2004_model_updated
* na: no drug effect
* cal: no drug effect
* herg IC50s = 100  uM, Hills = 1, Saturation levels = 0  %.
* iks: no drug effect
* ik1: no drug effect
* ito: no drug effect
* nal: no drug effect
* max free plasma concentration = 100 uM
* min free plasma concentration = 0 uM
* number of plasma concentrations = 13

It'd be an improvement if this wasn't appearing in the logs, so are there any suggestions for adjusting https://github.com/CardiacModelling/appredict-docker/blob/master/appredict-no-emulators/Dockerfile#L40-L47 to include that btl_base_warn_component_unused instruction?

I think this is unavoidable and harmless, does that sound right to you @jmpf ?

This is always run sequentially, and never in parallel, right?

Yep
