Introduction C++ language restrictions and the persistent memory programming paradigm imply serious restrictions on objects which may be stored on persistent medium. A user can access persistent memory with memory mapped files to take advantage of its byte addressability thanks to libpmemobj and …

Introduction vmemcache which we have recently described performs close to optimum when either all keys are approximately equally likely to be queried, or when all key:value pairs fit completely into the fastest form of memory you are willing to use. But, in many workloads, some keys are “hot” and …

Introduction libvmemcache is a volatile key-value store optimized for operating on NVDIMM based space. However, it can work with any filesystem whether it is stored in memory (tmpfs) or on any storage device. Consequently, libvmemcache will be significantly less performant if it is stored on the …

[Note: pmem::obj::vector<> is no longer experimental. The rest of the information in this blog post is still accurate.] Introduction The main idea behind pmem containers is to fully exploit persistent memory potential by designing optimized on-media layouts and algorithms for persistent memory …

Introduction It’s good practice to run persistent memory application under pmemcheck - a tool which is described here and here. In this post, we are going to learn about another tool for persistence correctness checking. As you might already know if you’ve read posts linked above, …
