Can Calculix run across multiple nodes?

1

I work in the Scientific Consulting Group at NAS. I need to install Calculix locally for one of my users. He wants to use it on our HPC Cluster. Can we use Calculix across nodes? I don’t see any MPI calls in the source. How does this work?

I have not yet tried it, but I believe precice should help with that: https://precice.org/fundamentals-literature-guide.html#parallel-and-high-performance-computing

Excellent! Many thanks! Now all I need is a little example which does not require the guy. I am not a calculix user myself, just building and optimizing for my users.

It can use MPI with a version I wrote using Intel’s cluster sparse solver . One can expect 10-30% speedup when running on two compute nodes vs. one node. See:
