CORFU: A distributed shared log
Mahesh Balakrishnan, Dahlia Malkhi, John D. Davis, Vijayan Prabhakaran, Michael Wei, Ted Wobber
Article No.: 10
DOI: 10.1145/2535930

CORFU is a global log which clients can append-to and read-from over a network. Internally, CORFU is distributed over a cluster of machines in such a way that there is no single I/O bottleneck to either appends or reads. Data is fully replicated...

A programmable memory controller for the DDRx interfacing standards
Mahdi Nazm Bojnordi, Engin Ipek
Article No.: 11
DOI: 10.1145/2534845

Modern memory controllers employ sophisticated address mapping, command scheduling, and power management optimizations to alleviate the adverse effects of DRAM timing and resource constraints on system performance. A promising way of improving the...

QoS-Aware scheduling in heterogeneous datacenters with paragon
Christina Delimitrou, Christos Kozyrakis
Article No.: 12
DOI: 10.1145/2556583

Large-scale datacenters (DCs) host tens of thousands of diverse applications each day. However, interference between colocated workloads and the difficulty of matching applications to one of the many hardware platforms available can degrade...
