The PMI interface is not exposed to directly use outside mpich library. You’ll need directly copy the pmi code from the MPICH source distribution. It is located in `src/pmi` folder. -- Hui Zhou From: kevin--- via discuss <[email protected]> Date: Monday, March 1, 2021 at 9:23 AM To: [email protected] <[email protected]> Cc: [email protected] <[email protected]> Subject: [mpich-discuss] Status of PMI in mpich Hello, I'm interested in using PMI from mpich programs. Can someone tell me what the status of PMI is? Is it usable or is it in an experimental state? Do I need to build mpich with any special flags to take advantage of it? I have a program developed on a Cray that I would like to port to other machines, but I get an error when compiling (using mpicc) about not finding pmi.h.
