Cobaya running issue computing convergence extended DE and massive neutrino models

Post by Helena Garcia » October 05 2021

The Cobaya code gets stuck when computing the convergence and learn new proposal covmat with extended dark energy and massive neutrino models. There are six chains, and five python processes are ongoing. Debug=true is on, but output isn’t very revealing. Output for recent representative run is below.

[2 : mcmc] Ready to check convergence and learn a new proposal covmat (waiting for the rest...)

What may be a possible solution for this problem? Thank you in advanced!
