This proves that my accumulation of buffers is a "clean" cache, which Linux can drop immediately when required. In the previous post, I looked at how global memory accesses by a group of threads can be coalesced into a single transaction, and how alignment and stride affect coalescing for various generations of… Hugepages is one of the techniques used in virtual memory management. In a standard environment, CPU allocates memory (virtual) for each process.
