location of PEme

I run some examples which are downloaded in https://github.com/Apress/programming-persistent-memory, I found it use disk instead of NVM to store or keep its persistence, because I use the function pmem_is_pmem to check its type, the function return false showing it is not pmem. I just want to know how to how to keep a file persistent in NVM, or what the persistent file in NVM looks like. I am a new-learner and do not understand its principle, and I would appricate if some body can help me.

Hi @cuichenxu,

Thanks for reading the book.

Q) Do you have a system with physical PMem installed or did you emulate it? Q) If you have physical PMem, do you have NVDIMM-N or Intel Optane Persistent Memory 100 or 200 Series Note: If you have the Intel Optane H10, H20, P4800X, P5800X, or P1600X, those are all block devices and you cannot use them as memory. Q) Are you using Linux or Windows?

Here are some resources to get you going:

• Getting Started Guide
• IPMCTL User Guide - For Intel Optane Persistent Memory Devices only
• NDCTL User Guide - For Linux Only
• Many of the concepts are covered in my Provision Intel® Optane™ Persistent Memory in Linux webinar. You'll find lots of other videos, webinars, and conference recordings on YouTube.
• Intel Optane Persistent Memory Quick Start Guide (QSG)
