Beating the I/O Bottleneck: A Case for Log-Structured Virtual Disks
With the increasing dominance of SSDs for local storage, today's network mounted virtual disks can no longer offer competitive performance. We propose a Log-Structured Virtual Disk (LSVD) that couples log-structured approaches at both the cache and storage ...
ASSOC COMPUTING MACHINERY2022HPCache: Memory-Efficient OLAP Through Proportional Caching
Anastasia Ailamaki, Periklis Chrysogelos, Hamish Mcniece Hill Nicholson
Analytical engines rely on in-memory caching to avoid disk accesses and provide timely responses by keeping the most frequently accessed data in memory. Purely frequency- & time-based caching decisions, however, are a proxy of the expected query execution ...
ACM2022On Calculating the Minimum Rate for the Cooperative Data Exchange Problem Over Fully Connected Networks
Michael Christoph Gastpar, Su Li
We study the cooperative data exchange problem for fully connected networks. In this problem, nodes make broadcast transmissions to recover a file consisting of K independent packets. Each node initially only possesses a subset of the packets. We propose ( ...
