MPAM-Style Cache Partitioning With ATP-Engine And gem5

The Memory Partitioning and Monitoring (MPAM) Arm architecture supplement allows for memory resources (MPAM MSCs) to be partitioned using PARTID identifiers. This allows privileged software, like OSes and hypervisors to partition caches, memory controllers and interconnects on the hardware level. This allows for bandwidth and latency controls to be defined and enforced for memory requestors. ... » read more

Microarchitectural Side-Channel Attacks And Defenses on NVRAM DIMMs

A new technical paper titled "NVLeak: Off-Chip Side-Channel Attacks via Non-Volatile Memory Systems" was published by researchers at UC San Diego, Purdue University, and UT Austin. This paper was included at the recent 32nd USENIX Security Symposium. Abstract: "We study microarchitectural side-channel attacks and defenses on non-volatile RAM (NVRAM) DIMMs. In this study, we first perform r... » read more
