Optimal Load Allocation for Coded Distributed Computation in Heterogeneous Clusters
DaeJin Kim, Hyegyeong Park, Junkyun Choi
Recently, coding has been a useful technique to mitigate the effect of stragglers in distributed computing. However, coding in this context has been mainly explored under the assum…

Hierarchical Coding for Distributed Computing
Hyegyeong Park, Kangwook Lee, Jy-yong Sohn +2
Coding for distributed computing supports low-latency computation by relieving the burden of straggling workers. While most existing works assume a simple master-worker model, we c…

LDPC Code Design for Distributed Storage: Balancing Repair Bandwidth, Reliability and Storage Overhead
Hyegyeong Park, Dongwon Lee, Jaekyun Moon
Distributed storage systems suffer from significant repair traffic generated due to frequent storage node failures. This paper shows that properly designed low-density parity-check…
