Build cmdstan2.26 with mpi

Hi,

How to build cmdstan2.26 with mpi enabled?
Is it enough in make/local
STAN_MPI=true
CXX=mpicxx
TBB_CXX_TYPE=gcc
all I need more switches?

Thanks for any advice.

Indeed, that should be it. Also see our guide here to double check: 14 Parallelization | CmdStan User’s Guide

Thank you.
Now I have problems when making boost library. Can you please advise?

I wonder if it is possible to use boost library which is already installed instead of making it. Is there a switch?
