Extending memory capacity with PMEM Databases such as Redis (an in-memory key-value open-source database) consume a lot of memory. Since fast access is essential for them, they use DRAM to store their data. DRAM is quite expensive and has limited capacity, so a solution we propose in this blog post …

At a high level, computing solves problems. These problems, even though different and individual, are sometimes somehow related. A new algorithmic challenge can usually be solved by bringing it down to a well-defined problem with an existing solution. Today, we will be talking about one of such …

Miniasync library provides a framework for the composition and execution of asynchronous tasks in C. To accommodate different user-defined tasks and various types of data that they take in, libminiasync makes use of macros. Using libminiasync for the first time can be challenging. There are multiple …

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 …
