When we, the PMDK team, want to check performance of our library, either to see if there was any regression or if our tweaks did a good job, we run benchmarks. One of them is FIO. It helps us simulate synthetic traffic of reads and writes to a pmem device. In this blog post I will introduce this …

Introduction X86/X64 systems do not typically interleave Persistent Memory Devices (also referred to as ‘modules’ or ‘DIMMs’) across sockets, so a two-socket system will have two separate interleave sets. To use these interleave sets as a single device requires using a …

We’re closing out 2017 with two big improvements to pmemkv: support for multiple storage engines, and an improved benchmarking utility based on db_bench. These changes set the stage for some interesting experiments to come next year, as we continue to add new features and tune performance of …

This is to announce a name change: The NVML project is now known as PMDK, the Persistent Memory Development Kit. Why the name change? The old name, NVML, made it sound like the project produced a single library that applied to Non-Volatile Memory. In reality, the project currently supports ten …

The last quarter was rather… peaceful. But nevertheless there were a few noteworthy things. FreeBSD & ARM We always asserted that our library is multi-platform and hardware agnostic… as long as your platform is a recent distribution of Linux (or Windows) on x86 hardware :) Two …
