Please use only 1 MPI process! We are currently working on the MPI parallelization of model selection. #131

Hello,

I am supporting a user at our University HPC center who is getting the error "Please use only 1 MPI process! We are currently working on the MPI parallelization of model selection." using version 2.2.2.4

The message is self-explanatory, but I was wondering if this has been implemented in the latest versions.

All the best,

Matthew

This is now supported in v2.3.X

Sorry, there was a misunderstanding. In fact, we have implemented MPI for model selection but the version is still under testing. When it is ready, we will release it.

Very similar issue here, a year later. Following the compilation guide for OpenMPI, I cannot even get minor parallelisation to run properly without either one of the processes segfaulting or giving me above error.

Is there any beta branch that I can look into? The only information I was able to find is a news article from that links back to the compilation guide. Blocking a cluster node for a single-CPU calculation is obviously not an option.
