pyfixest Grid Sharding
Problem
A regression grid (e.g. 2 measures x 3 FE structures x pooled+per-domain x 3
label variants ~ 70 models) on a 327k-row panel with high-cardinality director
FE ran ~55 s/model sequentially — ~65 min wall — on an RTX 5080 machine with
demeaner_backend="cupy64" on every call. The GPU was NOT the bottleneck.
