Data Management on Non-Volatile Memory: A Perspective

Web19 apr. 2024 · On the front of NVM, I will focus on the problem of how to allow the execution of transactions over NVM using unmodified commodity hardware TM (HTM) implementations. However, the reliance of commodity HTM implementations on CPU caches raises a crucial problem when applications access data stored in NVM from … Web5 okt. 2024 · In the second case, given NVM’s byte-addressability and low latency, data in NVM can be accessed via load and store instructions through the CPU caches without buffering it in DRAM. Specialized applications like databases usually implement their own management of resources and might desire to leverage load/store semantics.
