Uber's Failover Architecture: Reconciling Reliability and Efficiency in Hyperscale Microservice Infrastructure
Mayank Bansal, Milind Chabbi, Kenneth Bogh +21
Operating a global, real-time platform at Uber's scale requires infrastructure that is both resilient and cost-efficient. Historically, reliability was ensured through a costly 2x…
DR.FIX: Automatically Fixing Data Races at Industry Scale
Farnaz Behrang, Zhizhou Zhang, Georgian-Vlad Saioc +2
Data races are a prevalent class of concurrency bugs in shared-memory parallel programs, posing significant challenges to software reliability and reproducibility. While there is a…
EasyView: Bringing Performance Profiles into Integrated Development Environments
Qidong Zhao, Milind Chabbi, Xu Liu
Dynamic program analysis (also known as profiling) is well-known for its powerful capabilities of identifying performance inefficiencies in software packages. Although a large numb…
Unveiling and Vanquishing Goroutine Leaks in Enterprise Microservices: A Dynamic Analysis Approach
Georgian-Vlad Saioc, Dmitriy Shirchenko, Milind Chabbi
Go is a modern programming language gaining popularity in enterprise microservice systems. Concurrency is a first-class citizen in Go with lightweight ``goroutines'' as the buildin…
Protecting Locks Against Unbalanced Unlock()
Vivek Shahare, Milind Chabbi, Nikhil Hegde
The lock is a building-block synchronization primitive that enables mutually exclusive access to shared data in shared-memory parallel programs. Mutual exclusion is typically achie…
A Study of Real-World Data Races in Golang
Milind Chabbi, Murali Krishna Ramanathan
The concurrent programming literature is rich with tools and techniques for data race detection. Less, however, has been known about real-world, industry-scale deployment, experien…
OJXPerf: Featherlight Object Replica Detection for Java Programs
Bolun Li, Hao Xu, Qidong Zhao +4
Memory bloat is an important source of inefficiency in complex production software, especially in software written in managed languages such as Java. Prior approaches to this probl…
Optimistic Concurrency Control for Real-world Go Programs (Extended Version with Appendix)
Zhizhou Zhang, Milind Chabbi, Adam Welc +1
We present a source-to-source transformation framework, GOCC, that consumes lock-based pessimistic concurrency programs in the Go language and transforms them into optimistic concu…
DJXPerf: Identifying Memory Inefficiencies via Object-centric Profiling for Java
Bolun Li, Pengfei Su, Milind Chabbi +2
Java is the "go-to" programming language choice for developing scalable enterprise cloud applications. In such systems, even a few percent CPU time savings can offer a significant…
Pinpointing Performance Inefficiencies in Java
Pengfei Su, Qingsen Wang, Milind Chabbi +1
Many performance inefficiencies such as inappropriate choice of algorithms or data structures, developers' inattention to performance, and missed compiler optimizations show up as…
Redundant Loads: A Software Inefficiency Indicator
Pengfei Su, Shasha Wen, Hailong Yang +2
Modern software packages have become increasingly complex with millions of lines of code and references to many external libraries. Redundant operations are a common performance li…
Language Modeling at Scale
Mostofa Patwary, Milind Chabbi, Heewoo Jun +3
We show how Zipf's Law can be used to scale up language modeling (LM) to take advantage of more training data and more GPUs. LM plays a key role in many important natural language…
Correctness of Hierarchical MCS Locks with Timeout
Milind Chabbi, Abdelhalim Amer, Shasha Wen +1
This manuscript serves as a correctness proof of the Hierarchical MCS locks with Timeout (HMCS-T) described in our paper titled "An Efficient Abortable-locking Protocol for Multi-l…
