Just released mori 0.1.0 on CRAN β€” a new R package for sharing R objects across processes via OS-level shared memory.

Parallel R today duplicates your data in every worker's RAM. 8 workers Γ— 1 GB = 8 GB. mori puts it in shared memory once; every worker maps the same physical pages via R's ALTREP framework.

Works with any parallel backend that uses R's standard serialization, including mirai, parallel and callr.
