An Analytical Model-based Capacity Planning Approach for Building CSD-based Storage Systems
Hongsu Byun, Safdar Jamil, Jungwook Han +5
The data movement in large-scale computing facilities (from compute nodes to data nodes) is categorized as one of the major contributors to high cost and energy utilization. To tac…
Communication-Computation Efficient Secure Aggregation for Federated Learning
Beongjun Choi, Jy-yong Sohn, Dong-Jun Han +1
Federated learning has been spotlighted as a way to train neural networks using distributed data with no need for individual nodes to share data. Unfortunately, it has also been sh…
Election Coding for Distributed Learning: Protecting SignSGD against Byzantine Attacks
Jy-yong Sohn, Dong-Jun Han, Beongjun Choi +1
Recent advances in large-scale distributed learning algorithms have enabled communication-efficient training via SignSGD. Unfortunately, a major issue continues to plague distribut…
A Class of MSR Codes for Clustered Distributed Storage
Jy-yong Sohn, Beongjun Choi, Jaekyun Moon
Clustered distributed storage models real data centers where intra- and cross-cluster repair bandwidths are different. In this paper, exact-repair minimum-storage-regenerating (MSR…
Capacity of Clustered Distributed Storage
Jy-yong Sohn, Beongjun Choi, Sung Whan Yoon +1
A new system model reflecting the clustered structure of distributed storage is suggested to investigate interplay between storage overhead and repair bandwidth as storage node fai…
Secure Clustered Distributed Storage Against Eavesdroppers
Beongjun Choi, Jy-yong Sohn, Sung Whan Yoon +1
This paper considers the security issue of practical distributed storage systems (DSSs) which consist of multiple clusters of storage nodes. Noticing that actual storage nodes cons…
Capacity of Clustered Distributed Storage
Jy-yong Sohn, Beongjun Choi, Sung Whan Yoon +1
A new system model reflecting the clustered structure of distributed storage is suggested to investigate bandwidth requirements for repairing failed storage nodes. Large data cente…
