osdi 2021 accepted papers

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. This motivates the need for a new approach to data privacy that can provide strong assurance and control to users. When uploading your OSDI 2021 reviews for your submission to SOSP, you can optionally append a note about how you addressed the reviews and comments. This change is receiving considerable attention in the architecture and security communities, for example, but in contrast, so-called OS researchers are mostly in denial. Editor in charge: Daniel Petrolia . She also invented the spanning tree algorithm, which transformed Ethernet from a technology that supported a few hundred nodes, to something that can support large networks. OSDI '22 Technical Sessions | USENIX 64 papers accepted out of 341 submitted. We implement a variant of a log-structured merge tree in the storage device that not only indexes file objects, but also supports transactions and manages physical storage space. For general conference information, see https://www.usenix.org/conference/osdi22. Upon these two primitives, our system can scale to thousands of concurrent enclaves with high resource utilization and eliminate the high-cost initialization of secure memory using fork-style enclave creation without weakening the security guarantees. While several new GNN architectures have been proposed, the scale of real-world graphsin many cases billions of nodes and edgesposes challenges during model training. A graph embedding is a fixed length vector representation for each node (and/or edge-type) in a graph and has emerged as the de-facto approach to apply modern machine learning on graphs. ), Program Co-Chairs: Angela Demke Brown, University of Toronto, and Jay Lorch, Microsoft Research. Our evaluation shows that PET outperforms existing systems by up to 2.5, by unlocking previously missed opportunities from partially equivalent transformations. Welcome to the SOSP 2021 Website. SanRazor adopts a novel hybrid approach it captures both dynamic code coverage and static data dependencies of checks, and uses the extracted information to perform a redundant check analysis. We present TEMERAIRE, a hugepage-aware enhancement of TCMALLOC to reduce CPU overheads in the applications code. 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 is unfortunate because good OS design has always been driven by the underlying hardware, and right now that hardware is almost unrecognizable from ten years ago, let alone from the 1960s when Unix was written. Welcome to the 16th USENIX Symposium on Operating Systems Design and Implementation (OSDI '22) submissions site. Widely used log-search tools like Elasticsearch and Splunk Enterprise index the logs to provide fast search performance, yet the size of the index is within the same order of magnitude as the raw log size. USENIX Security '21 Summer Accepted Papers | USENIX We compare Marius against two state-of-the-art industrial systems on a diverse array of benchmarks. The wire-to-wire RPC response time through the nanoPU is just 69ns, an order of magnitude quicker than the best-of-breed, low latency, commercial NICs. Novel system designs, thorough empirical work, well-motivated theoretical results, and new application areas are all . It then feeds those invariants and the desired safety properties to an SMT solver to check if the conjunction of the invariants and the safety properties is inductive. Session Chairs: Dushyanth Narayanan, Microsoft Research, and Gala Yadgar, TechnionIsrael Institute of Technology, Jinhyung Koo, Junsu Im, Jooyoung Song, and Juhyung Park, DGIST; Eunji Lee, Soongsil University; Bryan S.

Acm Ccs 2022 - Sigsac His work has included the Barrelfish multikernel research OS, as well as work on distributed stream processors, and using formal specifications to describe the hardware/software interfaces of modern computer systems. 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. Reviews will be available for response on Wednesday, March 3, 2021. This budget is a scarce resource that must be carefully managed to maximize the number of successfully trained models. Evaluations show that Vegito can perform 1.9 million TPC-C NewOrder transactions and 24 TPC-H-equivalent queries per second simultaneously, which retain the excellent performance of specialized OLTP and OLAP counterparts (e.g., DrTM+H and MonetDB). Camera-ready submission (all accepted papers): 2 April 2021; Main conference program: 27-28 April 2021; All deadline times are . 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. We particularly encourage contributions containing highly original ideas, new approaches, and/or groundbreaking results. However, your OSDI submission must use an anonymized name for your project or system that differs from any used in such contexts. The chairs will review paper conflicts to ensure the integrity of the reviewing process, adding or removing conflicts if necessary. If in doubt about whether your submission to OSDI 2021 and your upcoming submission to SOSP are the same paper or not, please contact the PC chairs by email. Graph Neural Networks (GNNs) have gained significant attention in the recent past, and become one of the fastest growing subareas in deep learning. 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. Existing frameworks optimize tensor programs by applying fully equivalent transformations, which maintain equivalence on every element of output tensors. In some cases, the quality of these artifacts is as important as that of the document itself. These scripts often make pages slow to load, partly due to a fundamental inefficiency in how browsers process JavaScript content: browsers make it easy for web developers to reason about page state by serially executing all scripts on any frame in a page, but as a result, fail to leverage the multiple CPU cores that are readily available even on low-end phones. OSDI 2021 papers summary | hacklog Jaehyun Hwang and Midhul Vuppalapati, Cornell University; Simon Peter, UT Austin; Rachit Agarwal, Cornell University.

Mothy received a PhD in 1995 from the Computer Laboratory of the University of Cambridge, where he was a principal designer and builder of the Nemesis OS. This talk will discuss several examples with very different solutions. GoJournals goal is to bring the advantages of journaling for code to specs and proofs. Second, it innovates on the underlying cryptographic machinery and constructs a new private information retrieval scheme, FastPIR, that reduces the time to process oblivious access requests for mailboxes. The paper review process is double-blind. To evaluate the security guarantees of Storm, we build a formally verified reference implementation using the Labeled IO (LIO) IFC framework. OSDI is "a premier forum for discussing the design, implementation, and implications of systems software." A total of six research papers from the department were accepted to the . With her students, she had led research in AI, with a focus on robotics and machine learning, having concretely researched and developed a variety of autonomous robots, including teams of soccer robots, and mobile service robots. Distributed Trust: Is Blockchain the answer? DistAI generates data by simulating the distributed protocol at different instance sizes and recording states as samples. Papers so short as to be considered extended abstracts will not receive full consideration. 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. By submitting a paper, you agree that at least one of the authors will attend the conference to present it.

The 15th USENIX Symposium on Operating Systems Design and Implementation (OSDI '21) will take place as a virtual event on July 1416, 2021. The hybrid segment recycling chooses a proper block reclaiming policy between segment compaction and threaded logging based on their costs. A significant obstacle to using SC for practical applications is the memory overhead of the underlying cryptography. Today, privacy controls are enforced by data curators with full access to data in the clear. Publications | Mosharaf Chowdhury Artifact Evaluation - Systems Research Artifacts We present Nap, a black-box approach that converts concurrent persistent memory (PM) indexes into NUMA-aware counterparts. Copyright to the individual works is retained by the author[s]. We evaluate PrivateKube and DPF on microbenchmarks and an ML workload on Amazon Reviews data. Because DistAI starts with the strongest possible invariants, if the SMT solver fails, DistAI does not need to discard failed invariants, but knows to monotonically weaken them and try again with the solver, repeating the process until it eventually succeeds. Authors may upload supplementary material in files separate from their submissions. With the help of thousands of Lambda threads, Dorylus scales GNN training to billion-edge graphs. We propose PET, the first DNN framework that optimizes tensor programs with partially equivalent transformations and automated corrections. CLP's gains come from using a tuned, domain-specific compression and search algorithm that exploits the significant amount of repetition in text logs. Finding the inductive invariant of the distributed protocol is a critical step in verifying the correctness of distributed systems, but takes a long time to do even for simple protocols. Hence, kernel developers are constantly refining synchronization within OS kernels to improve scalability at the risk of introducing subtle bugs.

VLDB 2021 - 47th International Conference on Very Large Data Bases However, a plethora of recent data breaches show that even widely trusted service providers can be compromised. For general conference information, see https://www . In experiments with real DL jobs and with trace-driven simulations, Pollux reduces average job completion times by 37-50% relative to state-of-the-art DL schedulers, even when they are provided with ideal resource and training configurations for every job. This paper presents Zeph, a system that enables users to set privacy preferences on how their data can be shared and processed. See www.cs.cmu.edu/~mmv/Veloso.html for her scientific publications. First, it enables a caller to push a message to a callee in two hops, using a new way of assigning mailboxes to users that resembles how a post office assigns PO boxes to its customers. Used Zotero to organize papers about the stress and diffusion between anode and electrolyte and made a summary . Conference site 49 papers accepted out of 251 submitted.

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. Paper abstracts and proceedings front matter are available to everyone now. The abstractions we design for the privacy resource mirror those defined by Kubernetes for traditional resources, but there are also major differences. She developed the technology for making network routing self-stabilizing, largely self-managing, and scalable. There is no explicit limit to the response, but authors are strongly encouraged to keep it under 500 words; reviewers are neither required nor expected to read excessively long responses. Academic and industrial participants present research and experience papers that cover the full range of theory and practice of computer . 1 Acknowledgements: Paper prepared for the post-conference workshop on Food for Thought: Economic Analysis in Anticipation of the Next Farm Bill at the Agricultural and Applied Economics Association annual meeting, Austin, TX . This is especially true for DPF over Rnyi DP, a highly composable form of DP. Researchers from the Software Systems Laboratory bagged a Best Paper Award at the 16th USENIX Symposium on Operating Systems Design and Implementation (OSDI 2021). 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. If the conference registration fee will pose a hardship for the presenter of the accepted paper, please contact conference@usenix.org. Existing systems that hide voice call metadata either require trusted intermediaries in the network or scale to only tens of users. Just using Lambdas on top of CPU servers offers up to 2.75 more performance-per-dollar than training only with CPU servers. Concurrency control algorithms are key determinants of the performance of in-memory databases. USENIX discourages program co-chairs from submitting papers to the conferences they organize, although they are allowed to do so. Fortunately, we observe that the backups for high availability in modern distributed OLTP systems can be retrofitted to bridge the analytical queries and transactions in HTAP workloads. Despite having the same end goals as traditional ML, FL executions differ significantly in scale, spanning thousands to millions of participating devices. For more details on the submission process, and for templates to use with LaTeX, Word, etc., authors should consult the detailed submission requirements. After three years working on web-based collaboration systems at a startup in North Carolina, he joined Sprint's Advanced Technology Lab in Burlingame, California, in 1998, working on cloud computing and network monitoring. Only two types of supplementary material are permitted: source code described in the paper and formal proofs sketched in the paper. To resolve the problem, we propose a new LFS-aware ZNS interface, called ZNS+, and its implementation, where the host can offload data copy operations to the SSD to accelerate segment compaction. Many application domains can benefit from hybrid transaction/analytical processing (HTAP) by executing queries on real-time datasets produced by concurrent transactions. For conference information, see: . Accepted papers will be allowed 14 pages in the proceedings, plus references. The file system performance of the proposed ZNS+ storage system was 1.33--2.91 times better than that of the normal ZNS-based storage system. We present the results of a 1% experiment at fleet scale as well as the longitudinal rollout in Googles warehouse scale computers. P3 exposes a simple API that captures many different classes of GNN architectures for generality. We develop a prototype of Zeph on Apache Kafka to demonstrate that Zeph can perform large-scale privacy transformations with low overhead. When further combined with a simple caching strategy, our evaluation shows that P3 is able to outperform existing state-of-the-art distributed GNN frameworks by up to 7. Software Systems Laboratory Wins Best Paper Awards at the OSDI and Authors must limit their responses to (a) correcting factual errors in the reviews or (b) directly addressing questions posed by reviewers.
