All of the pmemobj library functions are thread-safe, with following two exceptions: pool management functions (open, close and friends) and pmemobj_root when providing different sizes in different threads - so as long as you are using this function the way it’s meant to be used you …

This is a topic I intentionally avoided not to introduce too much complexity too fast. The pmemobj library contains an implemented from scratch memory allocator, that was designed with persistent memory in mind. There are two separate APIs: non-transactional and transactional. Transactional …

In all of the previous post the code snippets and examples had persistent pointers (PMEMoid) without any type information - they were simple C structures. Very early in the development of the library we discovered that using something like that was extremely error-prone and generally difficult. …

By now you should be fairly familiar with the basics persistent memory programming, but to make sure the application is always in a consistent state you had to rely on your own solutions and tricks - like the length of a buffer in the previous example. Now, we will learn a generic solution provided …

In the previous post, you learned a little bit about the general concept of the persistent memory programming model, now it’s time to start the coding ;) Memory pools If you’ve read the overview you know that persistent memory is exposed by the OS as memory-mapped files, we call them …
