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…
Sentinel: Runtime Data Management on Heterogeneous Main MemorySystems for Deep Learning
Jie Ren, Jiaolin Luo, Kai Wu +2
Software-managed heterogeneous memory (HM) provides a promising solution to increase memory capacity and cost efficiency. However, to release the performance potential of HM, we fa…
EasyCrash: Exploring Non-Volatility of Non-Volatile Memory for High Performance Computing Under Failures
Jie Ren, Kai Wu, Dong Li
Emerging non-volatile memory (NVM) is promising for building future HPC. Leveraging the non-volatility of NVM as main memory, we can restart the application using data objects rema…
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…
