[Openmp-commits] [PATCH] D143775: [Libomptarget] Implement the host memory allocator with coarse memory

[Jon Chesterfield via Phabricator via Openmp-commits]

JonChesterfield added a comment.

I believe coarse/fine grain and accessibility are orthogonal concepts. If the coarse grain pool happens to have the accessibility properties of "target_host", then it'll work. That may be target specific and even order of pool iteration specific.

Much safer would be to identify a memory pool with the properties that the given allocator specifies and return that. Coarse grain means synchronised on kernel boundaries iiuc.

So what is a target_host_mem allocator?
