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
CosmoMC outputs 1 chain

Re: CosmoMC outputs 1 chain
Are you using mpirun (or runMPI.py)? Check it is being compiled with MPI.

I was able to solve the single output error using MPICH instead of OpenMPI. But the run is really slow while using mpich and even after submitting the run for 1 day the convergence r-1 was bad. Is there a specific reason to why its happening?
Thanks in advance
