Speeding up Distributed Request-Response Workflows
MSR, Bing, UIUC, Steklov Math Inst.

We show how to improve the tail latency of datacenter services which are built as workflows over many components by appropriately allocating additional resources across the various stages in the workflow. Also, even a small amount of incompleteness (i.e., returning partial results) can improve latency by a lot if used well.

Leveraging Endpoint Flexibility in Data-Intensive Clusters
UC Berkeley, MSR

Some network traffic in DCs does not care about where it is sent modulo some constraints. We consider using such traffic to better balance network load.

Achieving High Utilization with Software-Driven WAN

We show that given responsive networks and responsive applications adapting who gets to send how much, when, and along which network paths can improve network utilization without losing out on business priorities.
Virtualizing Traffic Shapers for Practical Resource Allocation
MSR, UC Berkeley

Can we make a switch with a few (4-8) traffic shapers (WFQs, Priority Queues) mimic the shaping behavior of a switch that has 100s-1000s of shapers?

Act for Affordable Data Care

Is there a market of data breach insurance, i.e., one that risk assesses users and businesses, incents better behavior from both and, pays out damages to recover from accidental data breaches?

Re-optimizing Data Parallel Computing
MSR, Bing, UCBerkeley
This ships in Bing's Cosmos clusters since December 2011.

How would execution plans for jobs in big data clusters change if given additional information about properties of the user code, data and how the code and data interact? Can we extract such properties at scale?

PACMan: Coordinated Memory Caching for Parallel Jobs
Ganesh Anantharanayanan, Ali Ghodsi, Andrew Wang, Dhruba Borthakur, Srikanth Kandula, Scott Shenker, Ion Stoica

How to build an input cache spanning a cluster of machines to speed-up parallel executions? Hint: Not LRU.

Recurring Job Optimizations in Scope
Bing, MSR
Industrial Track Paper

This describe how we gather statistics about code and data and use them to improve execution plans in SCOPE.

Scarlett: Coping with Skewed Content Popularity in MapReduce Clusters
UCBerkeley, MSR, Bing

Popularlity skew in input datasets slows down jobs, and a fix.

Sharing the Datacenter Network
MSR, Cornell, Azure, Bing

Adversarial network control, i.e., despite the traffic profile used by selfish or misbehaving tenants, how to ensure desired network allocation across entities?

Profiling Network Performance for Multi-tier Data Center Applications
Minlan Yu, Albert Greenberg, Dave Maltz, Jennifer Rexford, Lihua Yuan, Srikanth Kandula, Changhoon Kim

The many ways in which a vanilla network config is unsuitable for datacenter applications.

SideCar: Building Programmable Datacenter Networks without Programmable Switches
Alan Shieh, Srikanth Kandula, Emin Gun Sirer.

Can we programmatically process a non-trivial fraction of packets in the middle of the network? Then what?
