CosmoMC outputs 1 chain

Post by Rishi Babu » July 23 2020

Hi all
I'm running CosmoMC on ifort version 18.0.5.274 and OpenMpi on a campus server.
The number of processors used in the simulation is 8 but I get the chain output from only one.
Any help/suggestions would be appreciated.
Thanks

Are you using mpirun (or runMPI.py)? Check it is being compiled with MPI.
