summary

Eden is a far memory system that combines hardware page guards with a few programmer hints and a user‑level runtime to get app‑integrated performance with low developer effort. The implementation uses Linux userfaultfd plus lightweight software guards, shows 19.4–178% higher performance than Fastswap on memory‑heavy workloads, requires ~100× fewer code changes than AIFM, and needs only about 11 hot locations to capture 95% of far‑memory accesses for typical apps, effectively matching software‑guard performance.
