Intel Optane SSD/IMDT Microbenchmark
Symas Corp., September 2018 As noted above, the Optane SSDs also support a feature known as IMDT, Intel Memory Drive Technology which makes the Optane SSD appear as RAM to the OS. Now we're going to examine the performance of the previous Optane SSD workloads with increased amounts of RAM, and compare that to the performance of IMDT. First we'll continue using the 300GB databases as we operated on

NVMW 2024 - Program NVMW 2024
Abstract: Near data compute is an extension of computational storage to also include near memory compute. Recently, standards organizations have been busy completing standards for computational storage. SNIA created a first version of an architectural document in 2022 and an accompanying API in 2023. NVMe ratified a computational programs command set in early 2024. In addition, there are efforts w

Persistent Memory Development Kit The Persistent Memory Development Kit (PMDK) is a collection of libraries and tools. Tuned and validated on Linux OS, the libraries build on the DAX (Direct Access) feature allows applications to access persistent memory as memory-mapped files, as described in the SNIA NVM Programming Model. The source for PMDK is in this GitHub repository. The PMDK repository on
