PROV-IO+: A Cross-Platform Provenance Framework for Scientific Data on HPC Systems
Runzhou Han, Mai Zheng, Suren Byna +8
Data provenance, or data lineage, describes the life cycle of data. In scientific workflows on HPC systems, scientists often seek diverse provenance (e.g., origins of data products…
Understanding Persistent-Memory Related Issues in the Linux Kernel
Om Rameshwar Gatla, Duo Zhang, Wei Xu +1
Persistent memory (PM) technologies have inspired a wide range of PM-based system optimizations. However, building correct PM-based systems is difficult due to the unique character…
FS: A Scalable and Elastic Distributed File System Metadata Service using Serverless Functions
Benjamin Carver, Runzhou Han, Jingyaun Zhang +2
The metadata service (MDS) sits on the critical path for distributed file system (DFS) operations, and therefore it is key to the overall performance of a large-scale DFS. Common "…
On Failure Diagnosis of the Storage Stack
Duo Zhang, Om Rameshwar Gatla, Runzhou Han +1
Diagnosing storage system failures is challenging even for professionals. One example is the "When Solid State Drives Are Not That Solid" incident occurred at Algolia data center,…
Nature of System Calls in CPU-centric Computing Paradigm
Viacheslav Dubeyko, Om Rameshwar Gatla, Mai Zheng
Modern operating systems are typically POSIX-compliant with major system calls specified decades ago. The next generation of non-volatile memory (NVM) technologies raise concerns a…
