In the previous article, I wrote about a new upcoming Xeon platform feature, Data Streaming Accelerator (DSA) - a memory-to-memory DMA engine, and what opportunities and challenges it presents. I outlined the approach we are taking in Persistent Memory Development Kit (PMDK) to expose asynchronous …

One of the greatest benefits of Persistent Memory is that it’s directly accessible by the CPU. But that can also be one of its downsides for specific use cases. For example, if you want to use PMem as an ultra-fast storage device with low access latency. PMem as storage impedance mismatch The …

A software person perspective on new upcoming interconnect technologies. Existing Server Landscape Servers are expensive. And difficult to maintain properly. That’s why most people turn to the public cloud for their hosting and computing needs. Dynamic virtual server instances have been key to …

Introduction In the PMDK team, we focus on the quality of our codebase. One of the standard practices in the software development is a static code analysis, which improves the overall project quality and fixes bugs in the early stage of development. Since there is no silver bullet for avoiding bugs, …

If you are following our mailing group, you’ve probably noticed a stream of release announcements for libraries that are a part of PMDK. Here’s a recap of the most important new features and additions. libpmemkv 1.0 The primary goal of PMDK is enabling adoption of Persistent Memory. We …
