Description
Summary:
rstan::sbc() seems to be using parallel::mclapply() which is a serialized version on Windows. Thus, a more efficient implementation might be necessary for Windows users. A template might be the parallelization used in rstan::sampling().
Description:
See summary.
RStan Version:
2.19.2
R Version:
3.6.1
Operating System:
Windows 10

Research direction
Start with rstan::sbc() and compare its use of parallel::mclapply() with the parallelization used by rstan::sampling(). Investigate the Windows behavior and determine what implementation would provide effective parallel execution there. Done means SBC parallelization on Windows is no longer serialized and its behavior remains correct.
