Demystifying the Performance of HPC Scientific Applications on NVM-based Memory Systems
Ivy Peng, Kai Wu, Jie Ren +2
The emergence of high-density byte-addressable non-volatile memory (NVM) is promising to accelerate data- and compute-intensive applications. Current NVM technologies have lower pe…
UMap: Enabling Application-driven Optimizations for Page Management
Ivy B. Peng, Marty McFadden, Eric Green +5
Leadership supercomputers feature a diversity of storage, from node-local persistent memory and NVMe SSDs to network-interconnected flash memory and HDD. Memory mapping files on di…
Architecture-Aware, High Performance Transaction for Persistent Memory
Kai Wu, Jie Ren, Dong Li
Byte-addressable non-volatile main memory (NVM) demands transactional mechanisms to access and manipulate data on NVM atomically. Those transaction mechanisms often employ a loggin…
Characterization and Comparison of Application Resilience for Serial and Parallel Executions
Kai Wu, Qiang Guan, Nathan DeBardeleben +1
Soft error of exascale application is a challenge problem in modern HPC. In order to quantify an application's resilience and vulnerability, the application-level fault injection m…
Algorithm-Directed Crash Consistence in Non-Volatile Memory for HPC
Shuo Yang, Kai Wu, Yifan Qiao +2
Fault tolerance is one of the major design goals for HPC. The emergence of non-volatile memories (NVM) provides a solution to build fault tolerant HPC. Data in NVM-based main memor…
Performance Evaluation and Modeling of HPC I/O on Non-Volatile Memory
Wei Liu, Kai Wu, Jialin Liu +2
HPC applications pose high demands on I/O performance and storage capability. The emerging non-volatile memory (NVM) techniques offer low-latency, high bandwidth, and persistence f…
