I have problem regarding running models on multiple cores using either rstanarm or brms under windows and R 3.4.3… Running the model (simple regression) with 1 core runs fine but as soon as I what to use multiple cores, the “Viewer” opens, but actually nothing happens.
“Click the Refresh button to see progress of the chains starting worker pid=3408 on localhost:11456 at 15:00:36.757”
Has anyone experienced this problem before? The parallel::detectCores() function correctly identifies 8 cores.
Operating System: Windows
Interface Version: rstanarm 2.17.4
Compiler/Toolkit: RTools 3.4
