UPC++ Memory Kinds Prototype

This page is now obsolete!

This page was devoted to the "memory_kinds" prototype pf UPC++ initially released in Nov 2020 and intended only for use by developers with an interest in the memory kinds feature for CUDA GPU hardware.

The prototype has now been superceded by the latest stable release of UPC++, which incorporates all the prototype features. This includes the new GPUDirect RDMA (GDR) native implementation of memory kinds for NVIDIA-branded CUDA devices with Mellanox-branded InfiniBand network adapters.
