Towards Aggregated Asynchronous Checkpointing
Mikaila J. Gossman, Bogdan Nicolae, Jon C. Calhoun +2
High-Performance Computing (HPC) applications need to checkpoint massive amounts of data at scale. Multi-level asynchronous checkpoint runtimes like VELOC (Very Low Overhead Checkp…
High-Performance Ptychographic Reconstruction with Federated Facilities
Tekin Bicer, Xiaodong Yu, Daniel J. Ching +5
Beamlines at synchrotron light source facilities are powerful scientific instruments used to image samples and observe phenomena at high spatial and temporal resolutions. Typically…
VELOC: VEry Low Overhead Checkpointing in the Age of Exascale
Bogdan Nicolae, Adam Moody, Gregory Kosinovsky +2
Checkpointing large amounts of related data concurrently to stable storage is a common I/O pattern of many HPC applications. However, such a pattern frequently leads to I/O bottlen…
BlobSeer: How to Enable Efficient Versioning for Large Object Storage under Heavy Access Concurrency
Bogdan Nicolae, Gabriel Antoniu, Luc Bougé
To accommodate the needs of large-scale distributed P2P systems, scalable data management strategies are required, allowing applications to efficiently cope with continuously growi…
Distributed Management of Massive Data: an Efficient Fine-Grain Data Access Scheme
Bogdan Nicolae, Gabriel Antoniu, Luc Bougé
This paper addresses the problem of efficiently storing and accessing massive data blocks in a large-scale distributed environment, while providing efficient fine-grain access to d…
Enabling Lock-Free Concurrent Fine-Grain Access to Massive Distributed Data: Application to Supernovae Detection
Bogdan Nicolae, Gabriel Antoniu, Luc Bougé
We consider the problem of efficiently managing massive data in a large-scale distributed environment. We consider data strings of size in the order of Terabytes, shared and access…
