Early Evaluation of Intel Optane Non-Volatile Memory with HPC I/O Workloads
Kai Wu, Frank Ober, Shari Hamlin +1
High performance computing (HPC) applications have a high requirement on storage speed and capacity. Non-volatile memory is a promising technology to replace traditional storage de…
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…
High Performance Data Persistence in Non-Volatile Memory for Resilient High Performance Computing
Yingchao Huang, Kai Wu, Dong Li
Resilience is a major design goal for HPC. Checkpoint is the most common method to enable resilient HPC. Checkpoint periodically saves critical data objects to non-volatile storage…
Unimem: Runtime Data Management on Non-Volatile Memory-based Heterogeneous Main Memory
Kai Wu, Yingchao Huang, Dong Li
Non-volatile memory (NVM) provides a scalable and power-efficient solution to replace DRAM as main memory. However, because of relatively high latency and low bandwidth of NVM, NVM…
Application-Level Resilience Modeling for HPC Fault Tolerance
Luanzheng Guo, Hanlin He, Dong Li
Understanding the application resilience in the presence of faults is critical to address the HPC resilience challenge. Currently, we largely rely on random fault injection (RFI) t…
