We propose a new framework for computing the embeddings of large-scale graphs on a single machine. If you submit a paper to either of those venues, you may not also submit it to OSDI 21. However, the existing one-size-fits-all GNN implementations are insufficient to catch up with the evolving GNN architectures, the ever-increasing graph size, and the diverse node embedding dimensionality. The biennial ACM Symposium on Operating Systems Principles is the world's premier forum for researchers, developers, programmers, and teachers of computer systems technology. We propose PET, the first DNN framework that optimizes tensor programs with partially equivalent transformations and automated corrections. Calibrated interrupts increase throughput by up to 35%, reduce CPU consumption by as much as 30%, and achieve up to 37% lower latency when interrupts are coalesced. While verifying GoJournal, we found one serious concurrency bug, even though GoJournal has many unit tests. Welcome to the 16th USENIX Symposium on Operating Systems Design and Implementation (OSDI '22) submissions site. A graph neural network (GNN) enables deep learning on structured graph data. We present application studies for 8 applications, improving requests-per-second (RPS) by 7.7% and reducing RAM usage 2.4%. Sat, Aug 7, 2021 3 min read researches review. Devices employ adaptive interrupt coalescing heuristics that try to balance between these opposing goals. Our evaluation on the SPEC benchmarks shows that SanRazor can reduce the overhead of sanitizers significantly, from 73.8% to 28.062.0% for AddressSanitizer, and from 160.1% to 36.6124.4% for UndefinedBehaviorSanitizer (depending on the applied reduction scheme). Consensus bugs are extremely rare but can be exploited for network split and theft, which cause reliability and security-critical issues in the Ethereum ecosystem. Artifact Evaluation - Systems Research Artifacts NSDI 2021 - Research.com USENIX Security '21 Summer Accepted Papers | USENIX Just using Lambdas on top of CPU servers offers up to 2.75 more performance-per-dollar than training only with CPU servers. A scientific paper consists of a constellation of artifacts that extend beyond the document itself: software, hardware, evaluation data and documentation, raw survey results, mechanized proofs, models, test suites, benchmarks, and so on. Papers accompanied by nondisclosure agreement forms will not be considered. will work with the steering committee to ensure that the symposium program will accommodate presentations for all accepted papers. We particularly encourage contributions containing highly original ideas, new approaches, and/or groundbreaking results. To adapt to different workloads, prior works mix or switch between a few known algorithms using manual insights or simple heuristics. My paper has accepted to appear in the EuroSys2020; I will have a talk at the Hotstorage'19; The Paper about GCMA Accepted to TC; USENIX ATC '21 - HotCRP.com PDF Why Has Personality Psychology Played an Outsized Role in the Sam Kumar, David E. Culler, and Raluca Ada Popa, University of California, Berkeley. The conference papers and full proceedings are available to registered attendees now and will be available to everyone beginning Wednesday, July 14, 2021. We implement DeSearch for two existing decentralized services that handle over 80 million records and 240 GBs of data, and show that DeSearch can scale horizontally with the number of workers and can process 128 million search queries per day. See the Preview Session page for an overview of the topics covered in the program. Pollux is implemented and publicly available as part of an open-source project at https://github.com/petuum/adaptdl. Instead of choosing among a small number of known algorithms, our approach searches in a "policy space" of fine-grained actions, resulting in novel algorithms that can outperform existing algorithms by specializing to a given workload. Here, we focus on hugepage coverage. News Baris Kasikci's Home Page - Electrical Engineering and Computer Performance experiments show that GoNFS provides similar performance (e.g., at least 90% throughput across several benchmarks on an NVMe disk) to Linuxs NFS server exporting an ext4 file system, suggesting that GoJournal is a competitive journaling system. Concretely, Dorylus is 1.22 faster and 4.83 cheaper than GPU servers for massive sparse graphs. If you are uncertain about how to anonymize your submission, please contact the program co-chairs, osdi21chairs@usenix.org, well in advance of the submission deadline. Welcome to the 2021 USENIX Annual Technical Conference (ATC '21) submissions site! The blockchain community considers this hard fork the greatest challenge since the infamous 2016 DAO hack. First, Fluffy mutates and executes multi-transaction test cases to find consensus bugs which cannot be found using existing fuzzers for Ethereum. This paper addresses a key missing piece in the current ecosystem of decentralized services and blockchain apps: the lack of decentralized, verifiable, and private search. For example, traditional compute resources are replenishable while privacy is not: a CPU can be regained after a model finishes execution while privacy budget cannot. Authors of each accepted paper must ensure that at least one author registers for the conference, and that their paper is presented in-person at the conference. In this paper, we present P3, a system that focuses on scaling GNN model training to large real-world graphs in a distributed setting.

Ethereum is the second-largest blockchain platform next to Bitcoin. OSDI 2021 papers summary. Metadata from voice calls, such as the knowledge of who is communicating with whom, contains rich information about peoples lives. After request completion, an I/O device must decide either to minimize latency by immediately firing an interrupt or to optimize for throughput by delaying the interrupt, anticipating that more requests will complete soon and help amortize the interrupt cost. Session Chairs: Sebastian Angel, University of Pennsylvania, and Malte Schwarzkopf, Brown University, Ishtiyaque Ahmad, Yuntian Yang, Divyakant Agrawal, Amr El Abbadi, and Trinabh Gupta, University of California Santa Barbara. This fast path contains programmable hardware support for low latency transport and congestion control as well as hardware support for efficient load balancing of RPCs to cores. As the emerging trend of graph-based deep learning, Graph Neural Networks (GNNs) excel for their capability to generate high-quality node feature vectors (embeddings).

This talk will discuss several examples with very different solutions. Jiang Zhang, University of Southern California; Shuai Wang, HKUST; Manuel Rigger, Pinjia He, and Zhendong Su, ETH Zurich. She also has made contributions in network security, including scalable data expiration, distributed algorithms despite malicious participants, and DDOS prevention techniques. Based on the observation that real-world workloads always feature skewed access patterns, Nap introduces a NUMA-aware layer (NAL) on the top of existing concurrent PM indexes, and steers accesses to hot items to this layer. For conference information, see: . In particular, I'll argue for re-engaging with what computer hardware really is today and give two suggestions (among many) about how the OS research community can usefully do this, and exploit what is actually a tremendous opportunity. OSDI brings together professionals from academic and industrial backgrounds in a premier forum for discussing the design, implementation, and implications of systems software.

Four months after we reported the bugs to Geth developers, one of the bugs was triggered on the mainnet, and caused nodes using a stale version of Geth to hard fork the Ethereum blockchain. We also welcome work that explores the interface to related areas such as computer architecture, networking, programming languages, analytics, and databases. Poor data locality hurts an application's performance. Paper abstracts and proceedings front matter are available to everyone now. DeSearch then introduces a witness mechanism to make sure the completed tasks can be reused across different pipelines, and to make the final search results verifiable by end users. When registering your abstract, you must provide information about conflicts with PC members. However, a plethora of recent data breaches show that even widely trusted service providers can be compromised. OSDI takes a broad view of the systems area and solicits contributions from many fields of systems practice, including, but not limited to, operating systems, file and storage systems, distributed systems, cloud computing, mobile systems, secure and reliable systems, systems aspects of big data, embedded systems, virtualization, networking as it relates to operating systems, and management and troubleshooting of complex systems. Therefore, developers typically find data locality issues via dynamic profiling and repair them manually. Authors should email the program co-chairs, osdi21chairs@usenix.org, a copy of the related workshop paper and a short explanation of the new material in the conference paper beyond that published in the workshop version. We observe that scalability challenges in training GNNs are fundamentally different from that in training classical deep neural networks and distributed graph processing; and that commonly used techniques, such as intelligent partitioning of the graph do not yield desired results. USENIX Security '21 has three submission deadlines. USENIX, like other scientific and technical conferences and journals, prohibits these practices and may, on the recommendation of a program chair, take action against authors who have committed them. In this paper, we show how to address this inefficiency without requiring pages to be rewritten or browsers to be modified. Secure Computation (SC) is a family of cryptographic primitives for computing on encrypted data in single-party and multi-party settings. And yet, they continue to rely on centralized search engines and indexers to help users access the content they seek and navigate the apps. Despite having the same end goals as traditional ML, FL executions differ significantly in scale, spanning thousands to millions of participating devices. This paper describes the design, implementation, and evaluation of Addra, the first system for voice communication that hides metadata over fully untrusted infrastructure and scales to tens of thousands of users.

Sijie Shen, Rong Chen, Haibo Chen, and Binyu Zang, Institute of Parallel and Distributed Systems, Shanghai Jiao Tong University; Shanghai Artificial Intelligence Laboratory; Engineering Research Center for Domain-specific Operating Systems, Ministry of Education, China. We present NrOS, a new OS kernel with a safer approach to synchronization that runs many POSIX programs. Hence, CLP enables efficient search and analytics on archived logs, something that was impossible without it. We present selective profiling, a technique that locates data locality problems with low-enough overhead that is suitable for production use. Existing algorithms are designed to work well for certain workloads. Report - Systems Research Artifacts Software Systems Laboratory Wins Best Paper Award at OSDI 2022 2019 - Present. The experimental results show that Penglai can support 1,000s enclave instances running concurrently and scale up to 512GB secure memory with both encryption and integrity protection. PET discovers and applies program transformations that improve computation efficiency but only maintain partial functional equivalence. We first introduce two new hardware primitives: 1) Guarded Page Table (GPT), which protects page table pages to support page-level secure memory isolation; 2) Mountable Merkle Tree (MMT), which supports scalable integrity protection for secure memory. Instead, we propose addressing the root cause of the heuristics problem by allowing software to explicitly specify to the device if submitted requests are latency-sensitive. DMons targeted optimizations provide 16.83% speedup on average (up to 53.14%), compared to a baseline that uses the highest level of compiler optimization. AI enables principled representation of knowledge, complex strategy optimization, learning from data, and support to human decision making. We present DPF (Dominant Private Block Fairness) a variant of the popular Dominant Resource Fairness (DRF) algorithmthat is geared toward the non-replenishable privacy resource but enjoys similar theoretical properties as DRF.
