20,000 mallocs Under the Sea: Practical C++ PMR

• Ralph J. Steinhagen (GSI Helmholtzzentrum für Schwerionenforschung GmbH(GSI))

Room: C27 3.010 - C27 Ebene 3 Heap allocation isn’t "free" -- tight loops make that painfully obvious. We’ll cover `std::pmr` in practice: what made classic allocators awkward, how type erasure enables runtime memory policies, and when to pick `monotonic` vs `pool` resources. GNU Radio 4.0 examples include cache alignment, leak checks, and exception-safe migration of containers across resources — a pattern that also bridges Host-vs-GPU memory boundaries via `SYCL USM` and `CUDA Unified Memory`.
